EBR74796470 LG Refrigerator Main Control Board, the Assembly Where Every Reference Number Sits One Digit From a Different Board
Part EBR74796470 is an LG main PCB assembly, and four independent parts records describe it in exactly those words. What makes it awkward to buy has nothing to do with what it does. It has to do with what it is called. The assembly for the cabinet next along is EBR74796471, its retailer reference number is one higher, its stocking reference is one higher, its vendor code is one higher, and the refrigerator it belongs in wears a model code one higher too. Then the pattern turns around: the cabinet whose model code ends 25974 takes the board ending 470, while the cabinet ending 25973 takes the board ending 471. Nine numbers move together and one moves against the rest. That inversion is what this guide is written around.
What Does a Failing EBR74796470 Look Like From the Kitchen?
An EBR74796470 becomes a candidate when a French door LG cabinet holds power and lighting but stops getting cold, when frost seals the rear freezer wall because defrost never finishes, when the compressor circuit refuses to start on a proven outlet, and when several unrelated functions slide together over a couple of weeks.
Every cooling decision in these cabinets originates here. Sensor values arrive at this assembly, the schedule that governs defrost lives on it, and its outputs reach the compressor circuit, the evaporator and condenser fans, the ice hardware and the panel the owner touches. One arbitrator with that many duties rarely fails tidily. What owners describe instead is a spread of complaints with no mechanical relationship to one another, appearing close together in time.
- Interior lighting and panel both alive while neither compartment holds its set temperature
- Rear freezer wall growing a solid sheet of frost until airflow is choked off
- No sound at all from the machine compartment although the outlet has been proven live
- Fans running continuously, or never coming up at all, regardless of what the panel is set to
- Readouts appearing at the panel and clearing themselves, then returning within a day or two
- Ice production and cooling degrading during the same short period

Why Is a Cross-Reference Number Useless as a Second Check on This Board?
Because the neighbouring assemblies carry references that run consecutively. Published records give EBR74796470 an AP number ending 470, a stocking number ending 601 and a retailer catalogue number ending 022, while the board beside it holds 471, 602 and 023. Every layer increments together, so no layer can confirm another.
The video above shows where the applied label sits on an appliance control board and how to read it before packaging is opened. On this family that habit is the whole defence. Buyers are often told to confirm a purchase using an AP or PS reference from an old invoice, and here that advice quietly fails, because three consecutive assemblies were issued three consecutive references at every level of the catalogue. A transposed digit anywhere in the chain lands you on a real board for a real refrigerator, just not yours.
Which Faults Belong to the Assembly and Which Belong to What It Drives?
Ask how many separate systems have gone wrong. A single dead function with everything around it healthy describes the hardware that performs that function. Several unrelated functions drifting inside one short period describes the thing they all report to. On these cabinets that count settles most of the question before a meter comes out.
Treat every row as a testing direction and not as a verdict. These are French door refrigerators in which one assembly answers for two compartments, a defrost schedule, an ice supply and a through-door water path, which is why complaints originating in half a dozen places converge on this part far more often than the evidence supports.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Lights on, panel accepts settings, neither compartment cools | A cooling call that is never issued, or is issued and never acted on | Confirm the demonstration setting is off, then read each thermistor at its plug and watch every fan start. Impossible sensor values produce behaviour identical to a dead assembly. | Common |
| Freezer wall behind the rear panel packed hard with frost | Defrost is being scheduled and never completing | Meter the defrost heater, the thermal fuse and the defrost sensor first. Only the schedule belongs to the board; three inexpensive parts have to survive for the cycle to finish. | Defrost parts first |
| Freezer cold, fresh food side warm, air barely moving upstairs | Airflow between compartments, a damper or the fresh food fan | Look for a blade held by frost, then at the damper assembly. One compartment succeeding while the other fails is an airflow story before it is an electronic one. | Airflow first |
| Machine compartment silent, outlet proven live, panel lit | Either the switching stage on the assembly or the compressor start circuit | Listen for a start attempt that fades away against no attempt whatsoever. Those two sound similar at the door and point in opposite directions. | Separate the two |
| Cooling, defrost and ice all degrading across the same fortnight | A shared point of command rather than three coincidences | Clear thermistors and fans, confirm the defrost path, then weigh the assembly seriously. Simultaneous unrelated faults are the strongest argument this part ever gets. | Board-related |
Which Panel Readouts Argue for This Board and Which Argue Against It?
Sort them by what they name. A readout naming a fan, a sensor or a defrost attempt describes a component being observed, and replacing that component usually closes the job. A readout describing a relay, a lost conversation or a compressor circuit describes the observer. Meanings shift between LG series and revisions, so confirm yours in your own documentation.
That sorting exercise is worth doing before any lookup. No refrigerator reports which part has failed. It reports which circuit stopped answering as expected, and very often the silent circuit is a component this assembly merely watches. Two readouts deserve separate mention. One indicates a refrigerant problem that no electronics can address and needs certified equipment. Another is not a fault at all, and is described below.
| Group | What It May Indicate | Is It This Board? |
|---|---|---|
| Readouts naming a freezer or fresh food evaporator fan | Rotation feedback did not arrive. Frost against a blade, a worn motor or an open feed raises this well before cabinet logic would | Fan first |
| Readouts naming a compartment or defrost sensor | A shorted, open or physically impossible value. Published LG sequences for this generation begin at the plug, move to resistance, and reach the assembly last | Sensor first |
| Readouts describing a defrost attempt that timed out | The cycle ran its allotted window without the evaporator reaching temperature. Heater, thermal fuse and defrost sensor all sit between instruction and outcome | Test the defrost circuit |
| Readouts naming ice maker hardware | An ice fan, ice sensor or ice motor that stopped reporting. These are common and inexpensive on cabinets carrying a dedicated ice section | Ice parts first |
| Readouts describing communication lost with the display | Two assemblies that can no longer hear one another. The loom crossing the hinge gives out considerably more often than either board it joins | Harness before board |
| Readouts naming a condenser fan feedback signal | The machine compartment fan is not confirming that it turned. Dust packed into the condenser area and worn bearings both produce this | Clean and check first |
| Readouts describing a compressor relay problem | A switching stage this assembly owns. Of everything in the table this group leans furthest toward the board, though a start device and the compressor itself still deserve elimination | Board-related |
What Has to Be Cleared Before an EBR74796470 Is Worth Buying?
Six checks decide it: read all eleven characters on the label rather than the last three, confirm your model code and its production run against the documented fitment, prove the demonstration setting is off, meter both compartment thermistors, test the defrost heater with its thermal fuse, and turn every fan blade by hand.
This is the single check that matters most on this particular assembly. Three boards issued consecutively serve three different cabinets, and their catalogue references were issued consecutively as well. Nobody misreads a part number by accident when the neighbours are far apart. They misread it constantly when the neighbours are adjacent. Read the number left to right, out loud, and write it down before you shop.
Two of the cabinets documented against this number are named at one production run only. That trailing pair of digits after the slash on your rating plate is not decoration, and on this family it can be the difference between the right assembly and a board that mounts perfectly and behaves oddly afterwards. Copy the model code complete, including anything printed after the slash.
Nothing else feeds this assembly its picture of the cabinet. Give it a shorted or open reading and the cooling decisions it makes turn into nonsense, and nonsense from cabinet logic is indistinguishable from absent cabinet logic at the kitchen door. There is a reason the published LG diagnostic order for refrigerators of this era arrives at the board last. Thermistors are inexpensive and they fail with some regularity.
A freezer icing itself shut is among the most frequent complaints on cabinets of this size, and the assembly is seldom the reason. It schedules defrost; it does not generate heat. Completing a cycle requires current through a heater, a thermal fuse that has not operated, and a sensor still willing to report a temperature. Remove any one of those three and airflow strangles in precisely the same way.
Cooling can stop outright with no electronic fault involved when a blade is gripped by frost or a bearing has worn out of round. Each fan leaves its own fingerprint. A freezer side fan held by ice yields a cold freezer above a warming fresh food section. A condenser fan that has given up yields a refrigerator that runs without pause and never arrives at temperature.
A machine compartment that stays quiet is the complaint most often blamed on this assembly, and it is genuinely ambiguous. A failed start device, a seized compressor and a switching stage that no longer closes all produce the same silence at the kitchen door. What separates them is what happens in the first seconds after power returns.
How Much Work Is an EBR74796470 Replacement?
Our own product records place the EBR74796470 behind the rear access panel at the back of the refrigerator and put the job itself under thirty minutes for a confident owner. An independent parts record gives the same family a fifteen to thirty minute rating. Access, rather than skill, is what usually sets the pace.
Mechanically this asks very little. A few screws, harnesses released at their latches, an assembly lifted clear of its standoffs. The time goes into pulling a loaded French door cabinet far enough out to stand behind, and into remembering which plug belongs on which header. Give yourself room to work square to the back panel, and photograph the populated assembly before a single connector moves.
Does the EBR74796470 Fit Your LG or Kenmore Refrigerator?
A model lookup helps here, with one condition attached. The documented fitment reaches across three LG cabinet families and two Kenmore badges, and on two of those cabinets only a named production run is listed. Enter your code below, then confirm the result against the label on your existing assembly.

Which LG and Kenmore Models Are Documented Against the EBR74796470?
Independent parts records document the EBR74796470 against the LFX25974SB, LFX25974ST and LFX25974SW, the LFXS24626D and LFXS24626S at production run 00, the LFX21976ST at production run 07, and two Kenmore codes beginning 795.70322. A group of GC-L258V export designations appears in one record only.
Documented Fitment, Confirm Against Your Label
Three things are worth drawing out of that list. First, this assembly reaches across cabinets of genuinely different sizes, roughly twenty one, twenty four and twenty five cubic feet, so a capacity match proves nothing here. Second, the LFXS24626 pair and the LFX21976ST each appear at a single named production run, and our own product record names the same runs, so copy the digits after the slash on your rating plate. Third, the GC-L258V designations, quoted as GC-L258VQXD, GC-L258VSXD and GC-L258VSXM, turned up in one record only and are treated here as unconfirmed. Rating plate close but not exact?

Certified to meet or exceed original LG factory specifications. Tamper-evident hologram applied. Anti-static packaged and sealed for shipping.
EBR74796470 Specifications and Cross-Reference Part Numbers
LG catalogues the EBR74796470 as a main PCB assembly, and independent records describe it as the refrigerator main control board. The references recorded against it are AP5977470, PS11710601 and EAP11710601, plus vendor stocking codes and a retailer catalogue number in the 4119 series.
| Manufacturer part number | EBR74796470. Catalogued through LG parts channels under the assembly name PCB Assembly Main, and described in independent parts records as a refrigerator main control board for LG and Kenmore cabinets |
| Board type | Main control board. Four separate parts records describe it in those terms, and our own product record agrees. It is not a display assembly, not a dispenser panel, and not a compressor inverter module |
| What it controls | Compartment sensor inputs, cooling calls and compressor operation, evaporator and condenser fans, defrost scheduling, ice hardware, and communication with the display the owner touches |
| Cabinets served | Three LG French door platforms rather than one, spanning roughly twenty one to twenty five cubic feet, together with two Kenmore badged cabinets built on the same design |
| Cross references | AP5977470 is recorded against this number, with PS11710601 and EAP11710601 as its pair, alongside vendor codes ALG557842 and PD00057024 and a retailer catalogue number in the 4119 series. Every one of those has a near neighbour belonging to a different board |
| The neighbouring assemblies | EBR74796471 serves the LFX25973 family and EBR74796472 serves a group of bottom-mount cabinets. Their references increment in step with this one at every level, which is exactly why a reference number cannot be used to confirm a purchase here |
| Supply status | Two independent retailers list this number as currently supplied under its own identity, one of them in stock at the time we checked. No supersession is recorded in either direction. One national parts database returned no record for the number at all, which is a cataloguing gap rather than a discontinuation signal |
| Sibling caution | The EBR747964 group is large and its members are distinct boards with their own model lists. Sharing the first eight characters proves nothing about fitment, and here the shared characters run to the ninth |
| APU status | FailSafe Certified, 1-year warranty (registration required), same-day shipping* |
Is an EBR74796470 Worth Buying for a French Door LG Cabinet?
Once thermistors, fans, the defrost path and the compressor start circuit have been eliminated and the assembly is genuinely at fault, an EBR74796470 is usually the least expensive route back to a working refrigerator, because the appliance around it costs an order of magnitude more to replace.
What your options typically cost
What Goes Wrong After the Correct Board Has Been Fitted?
Four things undo an EBR74796470 repair: shopping from a reference number instead of the label, ignoring the production run printed after the model code, leaving a sensor or defrost fault in place that was the real cause, and returning a harness to a header it did not come from.
Never order this one from a reference number alone
An AP or PS number copied off an old invoice is normally a fine second check. On this assembly it is not, because the boards either side of it carry references that increment in lockstep. A single transposed digit lands you on a genuine LG board for a genuine LG refrigerator that happens not to be yours.
Copy the digits after the slash on your rating plate
Two of the cabinets documented against this number appear at one production run each. Skipping that suffix is easy, since most people read a model code as a word and stop at the letters. It is also the fastest route to a board that mounts correctly and then controls the refrigerator strangely.
Go back to the sensors before blaming the replacement
A thermistor stuck open or short hands the new assembly the same impossible value it handed the old one, and the cabinet behaves exactly as it did before the work started. Nothing on this list sends more perfectly good boards back to sellers.
Put every harness back where it came from
Neighbouring connectors on this assembly are similar in size and keying, and a plug seated one position across produces behaviour nobody can distinguish from a dead board. The photograph taken before removal is the quickest way out of that.
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 Imitate an EBR74796470 Fault?
Parts capable of impersonating this fault include the compartment thermistors, the defrost heater with its thermal fuse and defrost sensor, the evaporator and condenser fan motors, the damper assembly that meters air between compartments, and the compressor start device in the machine compartment.

EBR74796470 LG Refrigerator Main Control Board, Frequently Asked Questions
These answers cover how to separate this assembly from the two issued immediately after it, why the production run on your rating plate matters, whether a reference number can confirm the purchase, how the Kenmore codes relate, whether the number is still supplied, and what a lit but warm cabinet is really saying.
How do I tell the EBR74796470 apart from the EBR74796471?
By the model family, and by reading your label all the way through. Published records put this number on LFX25974 cabinets and the neighbouring number on LFX25973 cabinets. Notice which way that runs, because it is the opposite of what most people assume: the higher model code takes the lower part number. If you are working from memory, or from a number someone read to you over the phone, you have a one in two chance of getting it backwards. Photograph the applied label and order from the photograph.
My rating plate says LFX21976ST slash 07. Does that suffix matter?
On this assembly it does. The record that names the LFX21976ST names it at run 07, and our own product record does the same. The LFXS24626D and LFXS24626S are likewise named at run 00 in both places. That does not automatically mean other runs take a different board, but nobody has documented them here, and an undocumented run is not worth spending money against. If your suffix reads differently, send us the rating plate photograph before you order.
Can I confirm this board using an AP or PS number?
Not safely, and this is the unusual part. AP5977470, PS11710601 and EAP11710601 are the references recorded against this number, and the assemblies on either side carry references that increment by exactly one at every level, including the catalogue numbers used by individual retailers. Three consecutive boards, three consecutive references, three different refrigerators. On most parts a reference is a useful second opinion. Here it repeats the same risk in different digits.
My refrigerator is a Kenmore. Why is an LG part number on the board?
Because the cabinet was built by LG and sold under the Kenmore badge, which was ordinary practice for this class of refrigerator. Records name two Kenmore codes beginning 795.70322 against this assembly, and the leading 795 identifies the maker behind the badge. Read the label all the same, since neighbouring Kenmore codes in the same series belong to other assemblies in this group.
Is the EBR74796470 discontinued or superseded?
Nothing we found records a supersession in either direction. Two independent retailers list the number under its own identity, one of them showing stock at the time we looked. One large national parts database returned no record for the number at all, which reads as a cataloguing gap rather than a discontinuation, since the other sources carry it with no end-of-life note. Practically, you are buying a part that still exists under its own name.
A listing showed a GC-L258V code against this number. What is that?
It is an export designation for the same cabinet sold outside the United States, quoted as GC-L258VQXD, GC-L258VSXD and GC-L258VSXM. Only one of the records we consulted carried them, so we treat the group as unconfirmed rather than documented, and we have said so in the fitment list instead of quietly dropping it. If your rating plate carries a GC-L258V code, send it over with a photograph of the board label and we will verify the pairing before you spend anything.
My cabinet has lights, a working panel and no cooling. Is that enough to condemn the board?
On its own, no, although it is a reasonable starting point. Check three things first. Confirm the demonstration setting is off, because it lights everything and disables cooling completely by design. Read both compartment sensors at their plugs, since a wild value produces exactly this picture. Then stand at the machine compartment when power returns and listen for a start attempt. A refrigerator that is fully awake, has healthy sensors and never attempts to start makes a genuine case for the assembly. One that tries and fades is arguing about the compressor circuit instead.
