EBR41956418 LG Refrigerator Main Control Board, the LFX French Door Assembly Whose Cross References Now Lead Only to Closed Listings
Part EBR41956418 is the LG main board documented against the LFX21971, LFX21975, LFX25971 and LFX25975 French door refrigerators and a long list of Kenmore cabinets LG built on the same platform. Its paperwork is not contested and its fitment is not ambiguous. What is unusual is where every trail ends. Three independent parts records carry it, all three describe it as ended, none offers a successor, and the distributor channel LG itself supplies no longer returns a record for the number at all. The references stamped against it still resolve, so a search looks productive right up to the moment the page loads and says nothing can be ordered. This guide is for owners who have already hit that wall.
What Does a Failing EBR41956418 Look Like on an LFX French Door Cabinet?
An EBR41956418 becomes the suspect when an LFX21971 or LFX25971 class cabinet warms across both compartments while the dispenser panel still lights, when the freezer rear wall packs with ice because defrost stops finishing, when the compressor never audibly attempts a start on a live outlet, and when cooling, defrost and ice all drift together.
On this platform one assembly carries the whole cabinet. Compartment sensors report to it, defrost timing originates in it, and its outputs reach the compressor circuit, the fans, the damper, the ice hardware and the panel on the door. That concentration gives a failure here its shape. A single broken part usually breaks a single function, whereas an assembly that arbitrates everything takes several unrelated functions with it.
- Fresh food and freezer both climbing while the dispenser panel accepts settings normally
- Ice sheeted across the rear freezer wall until air stops reaching the fresh food side
- A machine compartment that stays silent on an outlet already proven live
- Ice and dispensed water stopping alongside a temperature complaint
- A cabinet that runs without pause and never reaches a set point
- Behaviour that changes after a power interruption and never settles back

Why Do the Reference Numbers for This Board Lead Only to Closed Listings?
Because the number has been retired without a replacement being named. Three separate parts records list EBR41956418 as no longer supplied by the manufacturer, and each states plainly that no substitute is available rather than naming a newer assembly. A fourth channel, the route LG itself feeds, returns no entry at all. AP4671992, PS3533844 and EAP3533844 still resolve to pages, but those pages exist to record that ordering has ended.
That changes how you should shop. On most LG boards a retired number hands you a successor: you search the old reference, a catalogue names something newer, you order that instead. Buyers arrive here expecting the same courtesy and do not get it. One record states the manufacturer no longer sells the part and that no substitute is available to it. A second reports it is no longer stocked and that none exists. A third calls it discontinued and suggests nothing in its place. Three catalogues reaching the same conclusion by three routes is about as firm as a negative finding gets.
So your cross references have stopped doing the work they normally do. An AP or PS number is usually a shortcut, a way of confirming the right assembly without squinting at a worn label. Here they identify the board correctly and still cannot buy you one through the original channel. That leaves the applied label as the only key that still functions, which is why the exercise in the video below matters more on this part than on most.
The video shows where the applied label sits on a control board and how to read it before packaging is opened. On a number in this position that reading is the whole verification. There is no successor to fall back on, and the four neighbouring assemblies sharing the first nine characters sit in the same supply position, so a mistake cannot be fixed by ordering a newer version. Photograph the label, read all eleven characters, and buy against the photograph.
Which Complaints Belong to Cabinet Logic and Which Belong to Cheaper Hardware?
Count the systems involved. One dead function surrounded by healthy ones describes the hardware that performs it. Several unrelated functions sliding together describes the assembly they all report to. On a refrigerator of this age that arithmetic matters more than usual, because the parts around the board have had many years to wear out on their own.
Read each row as a testing instruction, never a verdict. Cabinets of this generation are old enough that two genuine faults can be present at once, and a board condemned on a symptom that belonged to a sensor is an expensive way to learn that.
| What the owner reports | What it tends to mean | Where to test first | Board? |
|---|---|---|---|
| Both sections warming, panel lit and taking settings | Cooling is either not being requested or not being delivered | Watch each evaporator fan spin up, then read the compartment sensors at their plugs. A board fed impossible values behaves exactly like a board that has stopped working. | Common |
| Freezer rear wall solid with frost, airflow choked | Defrost is being scheduled but never completing | Meter the defrost heater, thermal fuse and defrost sensor before anything electronic. The board sets the schedule; three cheap parts have to survive for the cycle to finish. | Defrost parts first |
| Freezer cold, fresh food section warm | Air is not being moved or the damper is not opening | Check the fresh food evaporator fan and the damper travel by hand. An airflow fault produces a temperature split that looks convincingly like a logic fault. | Airflow first |
| Compressor never attempts a start although the outlet is live | Either the assembly is not commanding a start, or the start circuit cannot answer | Listen for repeated attempts that fade out versus complete silence. Those two sounds separate a drive problem from a command problem. | Board-related |
Do Cabinets of This Generation Give You a Readout Worth Trusting?
Less than you would hope. The dispenser panels on this generation can show a short set of two character indications, but the published set is thin compared with later LG platforms, several faults that matter most produce no readout at all, and reaching the diagnostic display needs a sequence that varies between series. Treat measurement and observation as the primary evidence and any readout as a hint that needs proving.
This matters because most published error code material for LG refrigerators describes platforms that arrived years after these cabinets were built. Owners find a table, look up a code their model never generates, and reason toward a conclusion the appliance never offered. The table below is organised around observations instead. Where your unit does surface an indication, confirm its meaning against documentation for your own series, since the same two characters carry different meanings across LG revisions.
| What you can observe without tools | What that observation narrows it to | Is it this board? |
|---|---|---|
| Panel lights, accepts settings, cabinet never gets cold | Either cooling is never being commanded, or a showroom setting has switched it off. The second costs nothing to rule out | Check the setting first |
| Heavy frost on the freezer rear wall with a warm fresh food side | Defrost is not completing. Heater, thermal fuse and defrost sensor stand between the instruction and the result | Test the defrost circuit |
| Displayed temperatures that a thermometer in the cabinet contradicts | A sensor reporting values that are wrong rather than absent, the failure mode most often mistaken for a failing board | Sensor first |
| Panel readable and responsive, machine compartment entirely silent | A refrigerator with power that has stopped asking for cooling and does not treat that as a fault | Board-related |
| Repeated clicking from the machine compartment every few minutes | A compressor attempting a start and being dropped by its overload. A drive side story that no board will change | Compressor circuit |
What Has to Be Cleared Before an EBR41956418 Is Worth Buying?
Five things: the eleven characters on your existing label, the compartment sensors read at their plugs, continuity through the defrost heater and thermal fuse, free rotation on every fan, and an honest listen at the compressor. With no successor published, the label check carries more weight than usual.
Four other assemblies begin EBR419564, serve different cabinets in the same LG generation, and sit in the same closed supply position. On a part with an active successor a misread digit costs you a return. Here it costs you a second search through a secondary market, because there is no current number anybody can send instead.
Nothing else feeds this assembly. Hand it a shorted, open or physically implausible reading and its cooling decisions become nonsense, and nonsense from cabinet logic is indistinguishable from dead cabinet logic at the kitchen door. The published LG diagnostic order for this era reaches the board last for a reason.
A freezer sealing itself shut with ice is the most frequent complaint on this platform, and cabinet logic is rarely the reason. The board schedules a defrost; it does not produce heat. Completion needs current through a heater, an intact thermal fuse, and a defrost sensor still willing to report a temperature. Remove any one and airflow strangles the same way every time.
Cooling can fail outright with no electronic fault at all when a blade is gripped by ice, a bearing has worn out of round, or a damper has stopped travelling. Each leaves its own fingerprint. A freezer side fan held by frost gives a cold freezer above a warm fresh food section. A condenser fan that has quit gives a refrigerator that runs without pause and never arrives.
How Much Work Is an EBR41956418 Swap on a French Door Cabinet?
Modest. Our own product record places the assembly behind a rear access panel and puts the swap under half an hour for a confident owner, and owner accounts published against this number describe completions from a quarter of an hour to an hour with nothing more than a screwdriver. The constraint is access: a full depth cabinet must be walked clear of the wall first.
Mechanically there is very little to it. A handful of screws, harnesses released at their latches, an assembly lifted off its standoffs. Time goes into getting a full depth cabinet forward enough to stand behind, and into remembering which plug belonged to which header. Photograph the populated board before touching a single connector.
Does the EBR41956418 Fit Your LG or Kenmore Refrigerator?
A model lookup is genuinely useful here. The documented fitment is broad and well recorded, covering four LG model families across their finishes and production runs plus more than thirty Kenmore cabinets LG built on the same platform. Check your model below, then confirm against the label on your existing board.

Which LG and Kenmore Models Are Documented Against the EBR41956418?
Published records document EBR41956418 against the LG LFX21971, LFX21975, LFX25971 and LFX25975 French door refrigerators in their recorded finishes and production runs, plus two groups of Kenmore cabinets built by LG, one in the 795.787 range and a larger one in the 795.797 range. The Kenmore entries outnumber the LG entries by a wide margin.
LG Models, Confirm Against Your Label
Kenmore Models Built by LG on the Same Platform
The Kenmore fitment runs wider than the grid shows. In full it also includes 795.78753802, 795.78759802, 795.78763802, 795.78764802, 795.79732900, 795.79733900, 795.79737900, 795.79742900, 795.79743900, 795.79747900, 795.79752901, 795.79752902, 795.79753901, 795.79753902, 795.79754900, 795.79754901, 795.79754902, 795.79757901, 795.79757902, 795.79757903, 795.79759900, 795.79759901, 795.79759902, 795.79759903, 795.79762900, 795.79763900, 795.79764900 and 795.79769900. Two points are worth flagging. The trailing run digits reach 903 on two stems, so read your whole number rather than stopping at the stem. And our own product record carries a narrower Kenmore list than the independent record does, missing 795.78753802, 795.78759802 and several deeper run digits, which is why the fuller list appears here.

How Is the EBR41956418 Restored to Spec? The FailSafe Precision Protocol
Every EBR41956418 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.
FailSafe Precision Protocol
Failure Pattern Analysis
Known failure patterns for the EBR41956418 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.
EBR41956418 Specifications and Cross-Reference Part Numbers
LG catalogues this assembly under the factory name PCB Assembly Main. Independent records describe it variously as a main control board and as a power control board assembly, which is one reason searches return inconsistent results. The references carried against it are AP4671992, PS3533844, EAP3533844, AH3533844, EA3533844 and the legacy number 1528401.
| Manufacturer part number | EBR41956418, catalogued through LG parts channels as PCB Assembly Main |
| Board type | Main control board for the cabinet. It is not a dispenser display assembly, not an ice maker board, and not a compressor inverter module. Records disagree about what to call it, not what it does, and the competing descriptions send you to different search results. Search the eleven character number instead |
| What it controls | Compartment sensor inputs, cooling calls and compressor operation, evaporator and condenser fans, damper operation, defrost scheduling, the ice and water hardware, and communication with the dispenser panel |
| Cross references | AP4671992, paired with PS3533844 and EAP3533844, alongside AH3533844 and EA3533844 in the same numeric series, a legacy reference 1528401, and vendor specific stock codes. Every one identifies the board correctly. None can currently be used to order it through the original channel |
| Supply status | Retired. Three independent parts records list the number as no longer supplied by the manufacturer, and all three state that no substitute is available rather than naming a successor. A fourth channel returns no record for the number at all. Boards in circulation are therefore original assemblies recovered and restored rather than new stock |
| The neighbouring assemblies | EBR41956415, EBR41956416, EBR41956417 and EBR41956419 all carry the factory name PCB Assembly Main and serve different cabinets in the same generation, including the LMX four door models and separate Kenmore ranges. All are recorded in the same retired position, and sharing the first nine characters proves nothing about fitment |
| APU status | FailSafe Certified, 1-year warranty (registration required), same-day shipping* |
Is an EBR41956418 the Right Spend on a Refrigerator of This Age?
It usually is, provided the sealed system is sound and the cheaper causes have been eliminated. These cabinets are old enough that the question deserves asking honestly, but a French door refrigerator restored for the price of a board is a different proposition from a new appliance and an old one to dispose of.
What your options typically cost
One caveat belongs here rather than buried below. If the compressor itself is failing, or a refrigerant leak is suspected, the arithmetic changes completely and no board will rescue it. That is where a conversation with a technician about the whole appliance is worth more than any part.
What Goes Wrong After a Correct Board Has Been Fitted?
Four things undo an EBR41956418 repair: buying against a neighbouring number in the same EBR419564 block, leaving in place the sensor or defrost fault that was the real cause, returning a harness to the wrong header, and judging the result before the cabinet has pulled down.
Check the number you ordered against the number you removed
Five assemblies share the first nine characters of this reference and serve different cabinets in the same LG generation. Because none has a published successor, a mistake here is slower to unwind than usual. Removed board and new board should read identically through all eleven characters.
Go back to the sensors and the defrost circuit before blaming the replacement
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 sends more sound boards back.
Return every harness to the header it came from
Adjacent connectors 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 fastest way back.
Give a full size cabinet time to recover
A French door refrigerator that has stood open, warm and emptied does not reach temperature in twenty minutes. Judging too early leads people to pull a perfectly good board back out. Close the doors, leave the settings alone, and come back hours later.
Still not working after all of the above?
Contact our team before returning anything. A brief conversation resolves most 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 This Cabinet Imitate a Board Fault?
Parts capable of impersonating an EBR41956418 fault include the compartment and defrost sensors, the defrost heater with its thermal fuse, the evaporator and condenser fan motors, the fresh food damper, and the compressor start components on a cabinet of this age.
Share your model number and a photo of your board's label. Our team will confirm the right part before you spend a dollar. No pressure, no obligation.

EBR41956418 LG Refrigerator Main Control Board, Frequently Asked Questions
These answers cover whether the number has been superseded, why the cross references still resolve to unavailable listings, what the Kenmore run digits mean, whether the neighbouring EBR419564 assemblies interchange, why records cannot agree what to call this board, and what a silent French door cabinet is telling you.
Has the EBR41956418 been superseded by a newer part number?
No successor has been published anywhere we could check. Three independent parts records list the number as no longer supplied by the manufacturer, and each says explicitly that no substitute is available rather than naming a replacement. A fourth channel, the one carrying current LG service stock, returns no entry at all. Most retired LG references hand you a newer number instead. This one does not, which is why boards in circulation are restored originals.
Why do AP4671992 and PS3533844 still return results if the part is discontinued?
Because those references identify the assembly, and identification does not expire when ordering does. AP4671992, PS3533844 and EAP3533844 still resolve to catalogue entries, and those entries exist to record what the number is and that it can no longer be bought through the original channel. The same goes for AH3533844, EA3533844 and the legacy 1528401. Treat them as confirmation you have the right board, not a route to ordering one.
My model is a Kenmore 795 number. Is this really an LG board?
Yes. These Kenmore cabinets were built by LG, which is why an LG assembly number sits inside them and why the Kenmore entries outnumber the LG ones. The verified list spans two ranges, seven cabinets in the 795.787 group and more in the 795.797 group. Read your full model number including the trailing run digits, which reach 903 on two stems. If your number is close to one on our list without matching exactly, send it to us first.
Will an EBR41956417 or EBR41956419 work in place of this one?
There is no published basis for treating them as interchangeable. Those two, with EBR41956415 and EBR41956416, carry the same LG factory assembly name and serve different cabinets in the same generation. One belongs to the LMX four door models rather than the LFX French door models at all, and the rest are documented against their own Kenmore ranges. Sharing nine characters is a manufacturing convenience, not a compatibility statement, and all four sit in the same retired position anyway.
Is this a main control board or a power board? Different listings call it different things.
It is the cabinet's main board, and the disagreement is over vocabulary rather than function. LG catalogues it as PCB Assembly Main. One independent record calls it a main control board, another a power control board assembly, a third simply a PCB assembly. All describe the same part behind the rear access panel, handling sensor inputs, cooling calls, fan and defrost control and the dispenser panel link. Search the eleven character number rather than a description and the confusion resolves itself.
Do these refrigerators show error codes I can look up?
Only to a limited extent, and less than the published material for newer LG refrigerators would suggest. The dispenser panel on this generation can show a small set of two character indications, but the set is thin, the sequence needed to reach it varies between series, and several of the faults that matter most produce no indication at all. Work from what you can measure and hear instead. Sensor resistance, continuity through the defrost heater and thermal fuse, free rotation on every fan, and whether the compressor attempts a start tell you more than a code table for another platform.
My LFX cabinet is completely silent. Is that enough to condemn the board?
On its own, no. Silence is equally consistent with an assembly that has stopped commanding cooling and with a compressor circuit that can no longer start, and the two are indistinguishable from across the kitchen. Listen at the machine compartment through several cycles. Repeated attempts that click and fade point at the drive side and its start components, prime suspects on a cabinet this old. No attempt at all, on a proven outlet with sensors and fans eliminated, makes a reasonable case for the board.
