EBR73093617 LG Refrigerator Main Control Board, the 31 Cubic Foot French Door Assembly No Catalogue Still Sells Under Its Own Number
Part EBR73093617 is the LG main control board fitted to the 31 cubic foot class French door refrigerators built around the LFX31945ST and LFX31995ST, together with their Kenmore badged twins in the 795.72062, 795.72063 and 795.72069 groups. If you have been searching that number and finding nothing that matches it, there is a reason. It was retired as a saleable line. Every parts route we followed, including the manufacturer's own model parts list for these refrigerators, now prints a single service assembly in the main board position instead, and that assembly stands in for a short run of neighbouring production numbers rather than for this one alone. This guide covers what the board is, which label numbers it answers to, how to tell a board fault from the far more expensive fault this platform is known for, and how to confirm fitment before anything is opened.
What Does a Failing EBR73093617 Look Like on a 31 Cubic Foot LG French Door?
This assembly comes under suspicion when both compartments drift warm while the panel stays lit and responsive, when ice output stops during a temperature complaint rather than on its own, when fan and sensor codes keep returning after frost is cleared, when the panel and the board stop talking to each other, and when a refrigerator on a proven live outlet makes no sound at all.
One assembly behind the rear cover runs almost everything on this platform. Compartment and defrost sensors report into it, every cooling and defrost decision originates there, and its outputs reach the compressor circuit, the condenser fan, the evaporator fans, the ice compartment hardware and the user panel. That concentration produces a recognisable pattern: instead of one clean casualty, several unrelated functions start slipping inside the same short window.
- Fresh food and freezer warming together while the panel lights up and accepts new settings
- Ice output stopping at the same time as a temperature complaint rather than on its own
- Fan or sensor codes returning within days of clearing frost and resetting the refrigerator
- A lit panel that no longer responds, or a communication code shown on the display
- Rear freezer panel glazing over because the defrost cycle starts and never completes
- No sound at all from the machine compartment once the outlet has been proven live

Why Does the Label on the Board Settle This Purchase Instead of the Model Plate?
Because the model plate route no longer returns this number. The manufacturer parts list for these refrigerators now shows the current service assembly in the main board position, not EBR73093617. Working from the characters printed on the board you removed is the only route that still lands on a definite answer.
The video above shows where the applied label sits on an appliance control board and how to read it before any packaging is opened. On this number that matters more than usual. A model lookup for these refrigerators returns the current service assembly, so a buyer who starts at the model plate never sees EBR73093617 at all and can easily conclude the part is wrong. A buyer who starts at the label sees the retired number, checks it against the short run of production numbers the service assembly stands in for, and has the answer in one step. Photograph the label while the board is still mounted and buy against the photograph.
Which Complaints on This Platform Point at the Board, and Which Point Somewhere Far More Expensive?
Count the failing systems first, then decide whether the fault sits upstream or downstream of the board. One dead function on an otherwise healthy refrigerator usually describes that function's own hardware. A total loss of cooling on this platform is the one complaint that most often turns out not to be the board at all.
Treat each row as a testing instruction rather than a verdict. This platform has a specific trap in it. A refrigerator that has gone completely warm looks electronic from the kitchen door, and on these 31 cubic foot French door cabinets that complaint leads to the compressor and the sealed system at least as often as it leads to the assembly behind the rear cover.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Both compartments warm, panel lit and taking settings | Cooling is either never requested, or requested and not delivered | Force a run with the board's own test function and watch what follows. If the compressor is being commanded and still will not run, the fault sits downstream of the board. | Test before deciding |
| Cabinet completely warm, compressor attempts a start and gives up | The compressor, its start device, or the sealed system rather than control logic | This platform carries a linear compressor with its own extended manufacturer parts term. Check what remains of that coverage before buying any part. | Compressor side first |
| Rear freezer panel iced over, weak airflow | A defrost cycle that starts and does not complete | Meter the defrost heater, the thermal fuse and the defrost sensor. Scheduling is the board's contribution, and three cheaper parts sit between the instruction and the result. | Defrost parts first |
| Ice output stops while both compartments hold temperature | Ice compartment hardware, the fill valve, or a frozen section of supply line | Confirm the freezer is reaching temperature, then check the fill valve and the ice compartment fan before treating the fault as electronic. | Ice hardware first |
| Panel lit but unresponsive, or a communication code shown | Two assemblies that can no longer hear each other | Inspect the loom between the panel and the board where it flexes, then the panel itself. Wire that moves on every door opening rarely outlasts the boards it joins. | Wiring before board |
| Cooling, defrost, ice and panel all slipping within the same few weeks | A shared point of control rather than four coincidences | When unrelated systems degrade together, what they share becomes the leading candidate. Clear the sensors and fans, then take the assembly seriously. | Board-related |
Which Display Codes on These Models Describe the Board, and Which Describe a Part It Only Watches?
Most codes on this platform name a component the board monitors, a fan, a sensor, a defrost attempt or the sealed system, and those close out by replacing that component. Only a small group describes the assembly itself or a conversation it takes part in. Published meanings shift between LG series and revisions.
Codes are read on the display of these models, and the sequence used to bring them up varies by model and series, so follow the instructions published for your own unit rather than a generic key combination. Sort what you find into two piles before spending anything. The larger pile names something the board is only reporting on. The smaller pile describes lost contact, or a switching stage inside the assembly. Where a code describes lost contact rather than a failed part, the loom is at least as likely a cause as the electronics.
| Code | What It May Indicate | Is It This Board? |
|---|---|---|
| Er CO | Communication lost between the main board and the display board. Board related, but the loom joining the two assemblies gives out more often than either board does. | Board or wiring |
| Er CF | No rotation signal coming back from the condenser fan. Inspect the fan, its wiring and the condenser itself before the board. | Condenser fan first |
| Er FF | Freezer evaporator fan not confirmed running. Ice against the blade is the most frequently reported cause on cabinets of this age. | Fan and frost first |
| Er rF | Fresh food evaporator fan not confirmed running. Owner accounts exist of this code being answered with a main board while the fault stayed. | Fan first |
| Er IF | Ice compartment fan or its motor not reporting. Frequently a blade frozen in place, which clears with a full defrost. | Ice fan first |
| Er FS / Er rS | A compartment sensor reading shorted, open or physically impossible. Testing starts at the connector and reaches the board last. | Sensor first |
| Er dH | A defrost cycle that ran its window without reaching temperature. Heater, thermal fuse and defrost sensor all sit between instruction and result. | Test the defrost circuit |
| dS | Defrost sensor shorted or disconnected. A cheap part, and one that makes healthy control logic behave badly. | Sensor first |
| CH E / CL E | A sealed system fault reported on the high or low side. No control board repairs this, and the work needs certified equipment. | Not the board |
| OF F | Display or demo mode is active and cooling is switched off. This is a setting rather than a fault. | Not a fault |
| 22 | Commonly reported as a compressor relay complaint, often heard as repeated clicking. It may describe a switching stage the board owns, and it may equally describe the compressor start circuit. | Separate the two |
What Should Be Ruled Out Before Ordering an EBR73093617?
Four checks decide it. Does your label read EBR73093617 or one of the neighbouring production numbers the current service assembly stands in for. Does the compressor run when the board's test function commands it. Do the sensors, defrost heater and thermal fuse measure in range. Is the ice fault arriving alone or alongside a temperature complaint.
This is the most important rule out on this platform and the reason boards in this position get replaced for nothing. These 31 cubic foot cabinets use a linear compressor, and the owner documentation published for them carries a ten year parts term on that compressor and a seven year parts term on the sealed system, far longer than the one year term covering the rest of the appliance. A compressor that has stopped producing takes the whole cabinet warm, which reads as an electronic failure from the kitchen door. The manufacturer's own symptom to part guidance for a warm refrigerator and freezer on this model leads with the compressor rather than the board.
Boards of this generation carry a test button on the assembly, behind the rear cover, and stepping through it forces states the refrigerator will not otherwise enter. That is the cheapest way to separate control logic from the hardware it commands. Published descriptions agree on the shape of the sequence: one state drives the compressor and fans continuously, another closes the damper, and a third turns the compressor and fans off while driving the defrost heater. Button position and any front panel alternative vary between models, so follow the instructions published for your unit rather than a generic sequence.
Sensors are the only inputs this assembly has. Hand it a shorted, open or implausible resistance and its cooling decisions turn to nonsense, and nonsense from a main board is hard to tell apart from a dead one at the kitchen door. Sensor codes appear on this platform for the freezer, the fresh food section, the defrost circuit and the ice compartment, and the published diagnostic order reaches the board last rather than first.
A freezer that ices itself shut is one of the commonest complaints on cabinets of this age, and the board is seldom the reason. The board schedules the cycle and supplies no heat itself. Completion needs current through a heater, a thermal fuse that has not operated, and a defrost sensor still reporting. Frost then chokes the evaporator fans, which raises fan codes that get misread as electronic faults.
How Much Work Is an EBR73093617 Replacement on a French Door Cabinet This Size?
The assembly sits behind the rear board cover at the back of the refrigerator, and the mechanical work is light: a short list of screws, connectors released at their latches, an assembly lifted clear. What takes the time is walking a full depth 31 cubic foot cabinet far enough out from the wall to stand square behind it.
The job itself is undemanding once you can reach it. The two things that cost time are floor space and memory. A cabinet this size is heavy and deep, and it has to come forward far enough to work square to the back panel. Then there is the wiring: this assembly carries a high connector count, and a plug returned one header across behaves exactly like a dead board. Photograph the populated assembly before releasing a single latch, and photograph the label at the same time. If you are not comfortable working with electronic components, a qualified appliance technician is always the right call.
Does the EBR73093617 Fit Your LG or Kenmore French Door Refrigerator?
Documented fitment is a small and consistent block: the LFX31945ST and LFX31995ST, three global GR-J318 designations, and a Kenmore badged run in the 795.72062, 795.72063 and 795.72069 groups. Records tie individual production runs to specific model suffixes, so the label on your existing board remains the deciding check.

Model lookups for these refrigerators now return the current service assembly rather than this number, so the applied white label on the board you removed is the one place EBR73093617 still appears in full. Click the image to zoom in.
Which LG and Kenmore Models Are Documented Against the EBR73093617?
Published fitment covers the LG LFX31945ST and LFX31995ST, the global designations GR-J318LQTP, GR-J318LSJP and GR-J318LSTP, and a Kenmore badged run numbered from 795.72062111 through 795.72069111. Records also pair the Kenmore short codes with the GR-J318 designations by production suffix, which is why the same board appears under both badges.
LG French Door, 31 Cubic Foot Class
LG Global and Export Designations
Kenmore Badged Twins, 795 Series
Short Catalogue Forms of the Same Models
Three things are worth knowing about this list. First, the LG and Kenmore entries are not separate designs. One record pairs the short code 72062 and GR-J318LQTP under the same production suffix, and pairs 72063 with GR-J318LSTP under another, so the badge on the door says nothing about the board inside. Second, coverage is recorded against particular production runs of these models rather than against the model number alone, so two cabinets wearing the same LFX31945ST plate can carry different assemblies. Third, one record carries a longer Kenmore list than another, and none of them publishes what the trailing digits encode, so we have not guessed. If your plate is close but not exact, photograph your board label and send it over before ordering.
How Is the EBR73093617 Restored to Spec? The FailSafe Precision Protocol
Every EBR73093617 sold by Appliance Pro USA goes through the FailSafe Precision Protocol, a proprietary 4-step process covering failure pattern analysis, precision diagnostic testing, proactive component replacement using equal or higher-rated parts, and final certification before the board ships.

Known failure patterns for the EBR73093617 are mapped before any board enters the process, so we know exactly which components to focus on for this specific board type.
Precision Diagnostic Testing
Multi-point diagnostic testing identifies faults and confirms overall board condition. Boards that do not pass diagnostic testing do not advance.
Proactive Component Replacement
Components identified through failure pattern analysis as common weak points are replaced using equal or higher-rated parts, before the board is cleared to ship.
Final Certification
Certified to meet or exceed original LG factory specifications. Tamper-evident hologram applied. Anti-static packaged and sealed for shipping.
EBR73093617 Specifications and Cross-Reference Part Numbers
LG catalogues this assembly as PCB Assembly Main, and it is the refrigerator main control board rather than a display module or a standalone inverter. Its own retired references are AP5688957, PS8690500 and EAP8690500. The current service assembly carrying this position is CSP30021077, with AP6978835 and PS12750330 alongside it.
| Manufacturer part number | EBR73093617. Catalogued by LG as PCB Assembly Main and described by independent parts records as the refrigerator main control board |
| Board type | Main control board. Four separate parts records describe it in those terms and none disagrees. It is not a display module, not an ice maker board, and not a standalone compressor inverter |
| What it controls | Compartment and defrost sensor inputs, cooling requests and compressor operation, condenser and evaporator fans, defrost scheduling, ice compartment hardware, and communication with the display board. One record specifically ties this assembly to power distribution for the ice maker |
| Appliance served | 31 cubic foot class LG French door refrigerators and their Kenmore badged twins, including cabinets sold with the door within a door compartment and the large in-door screen |
| Board location | Behind the rear board cover at the back of the refrigerator. Commonly reported at roughly eleven inches by six and a half inches, with a high connector count |
| Onboard diagnostics | A test function on the assembly steps the refrigerator through forced states covering compressor and fans, damper, and defrost. Button position and any front panel alternative vary by model, so follow the instructions published for your own unit |
| Current catalogue status | Retired as a saleable line. Every route we followed resolves to CSP30021077, the service assembly LG supplies for this position, and the manufacturer model parts list for these refrigerators prints CSP30021077 in the main board slot |
| What the service assembly absorbs | Records agree it stands in for EBR73093608 and EBR73093611 as well as EBR73093617. EBR73093603 appears in two records and EBR73093614 in one, so treat those two as likely rather than settled |
| Current generation references | CSP30021077, AP6978835 and PS12750330. The factory description carried against it is SVC PCB Assembly, Onboarding |
| Retired generation references | EBR73093617, AP5688957, PS8690500 and EAP8690500, plus a seven digit retail catalogue number beginning 2703 and assorted vendor stock codes |
| A caution about the word replaces | Aggregated listings mix the two generations together under one heading. AP6978835 and PS12750330 are not parts this board replaces, they are the current assembly's own identifiers in other catalogues |
| APU status | In stock, FailSafe Certified, 1-year warranty (registration required), same-day shipping* |
Is an EBR73093617 the Right Spend on a 31 Cubic Foot French Door Refrigerator?
Once the compressor, sealed system, sensors, defrost circuit and ice hardware have been eliminated, replacing the board is normally the least expensive route back to cooling. The current OEM service assembly for this position commonly lists in the mid three hundreds or above, a large share of what some replacement cabinets cost.
What your options typically cost
What Undoes an EBR73093617 Repair After the New Board Is In?
Four things undo this repair: leaving the compressor or sealed system fault that caused the complaint in place, leaving a failed sensor to hand the new assembly the same impossible reading, returning a connector to the wrong header on a board with this many of them, and judging the result before a cabinet this size has pulled down.
Go back to the compressor side before blaming the replacement
If the cabinet was completely warm before the swap and is completely warm after it, the most likely reading is that the board was never the fault. On this platform a total loss of cooling points at the compressor and the sealed system at least as often as at control logic, and that fault survives a board change untouched.
Re-check every sensor before declaring the new board faulty
A sensor stuck open or short hands the new assembly the same impossible reading it handed the old one, and the refrigerator behaves exactly as it did before the work started. Nothing on this list sends more good boards back to us.
Put every connector back where it came from
This assembly carries a lot of headers and neighbouring plugs are close in size and keying. A connector seated one position across, or seated without its latch engaging, produces behaviour nobody can tell apart from a dead board.
Give a cabinet this size time to recover
A 31 cubic foot refrigerator that has stood open, been emptied and gone warm does not reach temperature in twenty minutes. Judging the repair too early is how working boards get pulled straight back out. Complete a full power off reset, close the doors, leave the settings alone, and come back several hours later. Ice output can take longer still.
Still not working after all of the above?
Contact our team before returning anything. A brief conversation resolves the majority of post-install situations. We stand behind every board we sell and are here to help you get the result you need.
Which Cheaper Parts on These Refrigerators Imitate a Board Failure?
Components capable of impersonating an EBR73093617 fault include the linear compressor and its start device, the compartment and defrost sensors, the defrost heater and thermal fuse, the condenser and evaporator fan motors, the ice compartment fan and fill valve, and the display board with the loom that reaches it.

EBR73093617 LG Refrigerator Main Control Board, Frequently Asked Questions
These answers cover why no catalogue still sells this number, which neighbouring production numbers the current service assembly stands in for, how to separate a board fault from the compressor on this platform, what the test function on the board is for, which display codes actually point here, and whether a replacement needs any setup.
My board is labelled EBR73093617 but every listing shows CSP30021077. Are they the same part?
They occupy the same position, and CSP30021077 is what the catalogue now supplies for it. EBR73093617 is a production number printed on the assembly itself. CSP30021077 is the service assembly LG supplies in its place, carried under the factory description SVC PCB Assembly, Onboarding, with AP6978835 and PS12750330 as its matching references. Five independent records route this number to that assembly, and the manufacturer model parts list for these refrigerators now prints CSP30021077 in the main board position. What matters for your purchase is that your label appears in the group the service assembly stands in for, not that the digits match a current catalogue line.
My label reads EBR73093608, EBR73093611 or EBR73093603 instead. Does that change anything?
For the first two, no. Every record we consulted groups EBR73093608 and EBR73093611 with EBR73093617 under the same service assembly, so all three route to the same replacement position. EBR73093603 appears in that group in two records and EBR73093614 in one, which is weaker evidence, so treat those two as likely rather than settled and send us a photograph of the label before ordering. The rest of the EBR730936 range is a different matter. Sharing the first eight characters proves nothing, and neighbouring numbers in that range serve other cabinets with their own model lists.
The refrigerator is completely warm. How do I tell the board from the compressor before I spend anything?
This is the question that matters most on this platform, because a total loss of cooling here leads to the compressor and the sealed system at least as often as to the board. Two checks separate them cheaply. First, find your warranty documentation: the owner documentation published for these models carries a ten year parts term on the linear compressor and a seven year term on the sealed system, well beyond the one year covering everything else, so the expensive part may still be covered. Second, use the test function on the board to force a run and watch what follows. If the compressor is being commanded and still will not run, the fault is downstream of the board and a new board will not change it.
What is the test button on the board for, and should I use it?
It puts the refrigerator into forced operating states it will not enter on its own, which is the cheapest way to separate control logic from the hardware it commands. Published descriptions agree on the shape of it: one state runs the compressor and fans continuously, another closes the damper, and a third turns the compressor and fans off while driving the defrost heater. It is genuinely useful before buying a board. Two cautions apply. Button position and any front panel alternative vary between models, so follow the instructions published for your own unit rather than a generic sequence, and disconnect power before removing the rear cover or reaching near the assembly.
My display shows Er rF, Er FF or Er IF. Does that point at this board?
Usually not. Those three name an evaporator or ice compartment fan that has not confirmed rotation, and on cabinets of this age the most frequently reported cause is frost holding a blade rather than a failed assembly. There is a documented owner account of one of these codes being answered with a main board while the fault continued afterwards. Clear the frost completely, turn each blade by hand, check the fan wiring, and only then consider the board. The codes that lean toward the board on this platform are the communication code between the main board and the display, and the compressor relay complaint often heard as repeated clicking.
Ice output stopped but both compartments are holding temperature. Is that this board?
It can be, and this is one of the few places where the board is a reasonable early suspect rather than a last resort, because one parts record ties this assembly specifically to power distribution for the ice maker. It is still not the first thing to check. Confirm the freezer is genuinely reaching temperature, look for a blade frozen in the ice compartment fan, check the fill valve and the supply line for a frozen section, and inspect the ice module itself. If ice output failed on its own with everything else healthy and those parts test good, the assembly moves up the list. If ice output failed alongside a temperature complaint, treat it as one symptom of a larger fault rather than an ice problem.
Does a replacement need programming, and why does the factory name say onboarding?
Onboarding is LG's own description for this service assembly rather than an instruction to the installer, and no source we consulted publishes a required programming step for it. One record describes the installation as straightforward. That said, some LG units can call for a firmware or configuration step after a board change, and that work should be handled by a qualified technician. A board that has been flashed or reprogrammed is generally not returnable, so confirm the board resolves your fault before anything is altered. Follow the instructions published for your model rather than a sequence borrowed from another brand.
