EBR87463764 LG Refrigerator Main Control Board, the L268 Assembly Chosen by the Last Character of a Model Suffix
Part EBR87463764 is the LG main control board documented against the L268 cabinet, a platform LG publishes under two model stems at once. Its records carry GM-L268N designations on one side and GR-L268N designations on the other, and no other assembly in this run spans both. That would be a curiosity and nothing more, except that neighbouring assemblies serve the same L268 stems under a different destination suffix. Three separate boards therefore appear against model codes that look identical until the final character. This guide is built around that character, because here it is the whole of the decision.
What Does an EBR87463764 Fault Look Like Before Anyone Opens the Back?
An EBR87463764 fault usually shows as several unrelated functions slipping at once on an L268 cabinet: compartments drifting warm while the panel stays lit, a defrost cycle that never completes, fans that do not start with the compressor, or a refrigerator with power and no cooling call at all. Independent parts records and our own product record both describe this number as the main control board.
Everything this cabinet decides passes through one assembly. Sensors report into it, cooling calls originate from it, and its outputs reach the compressor circuit, the fans, the defrost schedule, the ice hardware and the panel the owner reads. A part carrying that many jobs rarely fails cleanly. What people describe instead is a refrigerator that has turned unreliable across several systems inside a few weeks, none of which share a wire with any of the others.
- Both compartments losing temperature together while the display still accepts settings normally
- Frost packing the freezer rear wall because a defrost cycle keeps starting and never finishes
- A fan that should run with the compressor staying silent, or running when nothing is calling for it
- Readouts appearing on the panel for circuits that measure correctly when they are tested
- A refrigerator with a live outlet, a lit panel and no attempt at cooling whatever the setting
- Ice, water and cooling all becoming intermittent inside the same short window
Three assemblies in this run answer to L268 model stems. The letters after the dot decide which one is yours.
Why Does the Character After the Dot Decide This Board and the Model Stem Not?
On the L268 platform the model stem is shared and the destination suffix is not. Records document GR-L268NSSM and GR-L268NKSM cabinets ending ASTCNAA, ASTCNAB and ASBCNAA against the EBR87463764, while the same two stems ending ASTCNA2 and ASBCNA2 are documented against two different assemblies. The letter or digit closing that suffix is the only published discriminator.
Set the published fitment for this group beside itself and the shape of it becomes obvious. A GR-L268NSSM cabinet whose suffix ends in a letter belongs here. One whose suffix ends in the digit 2 does not, and two candidate assemblies wait for it rather than one. Nothing earlier in the model code separates them: same prefix, same capacity figure, same finish letters, same everything up to the final character of a suffix that plenty of listings simply drop.
What lifts this above coincidence is that the identical split repeats one capacity class down. The L228 cabinets in the same run divide the same way, suffixes ending in 2 against one assembly and suffixes ending in A or B against another. Two platforms, one rule, applied consistently. That is a pattern rather than a filing accident, and it is why this guide asks you to read to the end of the suffix rather than the end of the stem.
The video shows where the applied label sits on an appliance control board and how to read it before packaging is opened. Do the same on your rating plate, because the two documents answer different halves of the question here. The plate carries the prefix, stem and suffix that decide which assembly LG specified for your cabinet. The board label carries the eleven characters of whatever assembly is actually fitted, which after a previous repair is not always the same thing. Photograph both and buy against the pair.
Which Complaints Justify Suspecting This Assembly and Which Do Not?
A complaint justifies suspecting the EBR87463764 when systems that share nothing but this board degrade together. A single failed function on an otherwise healthy L268 cabinet almost always belongs to the component that performs it, not to the assembly that schedules it. The table below sorts the common presentations into those two groups.
Read every row as a direction for testing and not as a verdict. The exercise is arithmetic rather than electrical: count how many independent systems are misbehaving, then ask what they have in common. One system in trouble points at that system. Four point at whatever they all report to.
| What the owner describes | What that generally indicates | Where to look first | Weight |
|---|---|---|---|
| Fresh food and freezer warming together, panel still bright and accepting settings | Cooling is being requested and not delivered, or was never requested at all | Confirm each evaporator fan spins up, then read the compartment thermistors at their plugs. An assembly handed impossible values acts exactly like one that has quit thinking. | Common |
| Freezer back wall carrying heavy ice, airflow almost stopped | Defrost keeps beginning without completing, or its heating path has opened | Meter the defrost heater, its thermal fuse and the defrost sensor first. Scheduling is what this board contributes; three low cost parts have to survive for the cycle to finish. | Defrost parts first |
| Ice production stops while water still dispenses and temperatures hold | The ice maker assembly, its fill valve or its own sensor | Verify the ice compartment reaches temperature and the water path is not frozen before considering cabinet logic. One failed subsystem on a healthy refrigerator is a local story. | Ice hardware |
| Panel dark or unresponsive while cooling continues normally | The display assembly or the loom that bends at the hinge | Inspect the door harness at its flex point, then the panel. Wire that articulates thousands of times gives out ahead of the electronics at either end of it. | Harness first |
| Cooling, defrost and ice all deteriorating inside the same few weeks | A shared point of command rather than three coincidences | Clear the sensors and fans, then weigh this assembly seriously. Unrelated systems slipping together is the closest thing to a signature this fault has. | Board-related |
What Is an LG Panel Readout Actually Naming on a Cabinet This Size?
An LG readout names the circuit that stopped answering as expected, not the part that failed. Most readouts on an L268 cabinet point at a sensor, a fan, a heater or a length of wire that the EBR87463764 monitors rather than at the assembly itself. Confirm every meaning in your own model's documentation before buying anything.
That distinction is worth carrying into any code lookup. A refrigerator cannot tell you which component has failed. It can only report which circuit returned an answer it did not accept, and very often that circuit belongs to an inexpensive part sitting some distance from the board. Where a readout describes lost communication rather than a bad reading, wiring is at least as likely a cause as electronics.
| Family of readout | What it generally describes | Weight |
|---|---|---|
| Readouts naming an evaporator fan | Rotation was not confirmed. Ice touching a blade, a tired motor or an open feed raises this long before cabinet logic would | Fan first |
| Readouts naming a compartment sensor | A value that is open, shorted or physically impossible. Published LG sequences for cabinets of this generation begin at the plug, move to resistance, and arrive at the board last | Sensor first |
| Readouts naming the defrost attempt or its sensor | Defrost ran its window without reaching temperature. Heater, thermal fuse and defrost sensor all sit between the instruction and the result | Test the defrost circuit |
| Readouts naming ice compartment hardware | An ice fan, ice sensor or ice motor that stopped reporting. These are common, cheap, and unrelated to how the cabinet cools | Ice parts first |
| Readouts describing lost contact with the door panel | Two assemblies that can no longer hear each other. The loom crossing the hinge fails considerably more often than either end of the conversation | Harness before board |
| Readouts describing a compressor relay or a sealed system fault | Either a switching stage this board owns, or a refrigeration problem no electronics can solve. Sealed system work requires certified equipment and a qualified technician | Separate the two |
| No readout at all while the cabinet stays warm | A refrigerator that has quietly stopped asking for cooling and does not regard that as a fault. This leans further toward the assembly than anything else in the table | Board-related |
What Has to Be Eliminated Before Ordering an EBR87463764?
Before ordering an EBR87463764, settle the suffix on your rating plate, then eliminate the compartment sensors, the defrost heater with its thermal fuse and sensor, every fan, and the ice hardware. Each of those costs a fraction of a main control board and each can imitate one convincingly on an L268 cabinet.
The stem alone cannot choose between three assemblies. The suffix can.
A false reading produces a false decision, every time.
Three cheap parts stand between the instruction and the outcome.
Ice contact and worn bearings both stop heat transfer with no electronics involved.
It runs hardware that has nothing to do with how the cabinet cools.
How Demanding Is an EBR87463764 Replacement in Practice?
Our own product record puts this replacement under 30 minutes with basic hand tools, working at the rear access panel with the refrigerator unplugged and pulled clear of the wall. The mechanical work is straightforward. The care goes into the connector positions and into confirming the suffix before the anti-static bag is opened.
A handful of screws, harnesses released at their latches, an assembly lifted from its standoffs. Nothing in that sequence is difficult. Time goes instead into moving a heavy full depth cabinet forward far enough to stand square behind it, and into tracking which plug belonged to which header. Photograph the populated board before a connector is touched and reassembly takes care of itself.
Does the EBR87463764 Fit Your LG Refrigerator?
The EBR87463764 is documented against GM-L268NKSM and GM-L268NSSM cabinets with ASBCNA2 and ASTCNA2 suffixes, and against GR-L268NSSM and GR-L268NKSM cabinets with ASTCNAA, ASTCNAB and ASBCNAA suffixes. One record also names the LFXS26973S. Enter your model code below, then confirm against the label on your board.
Model Number Check
Enter your refrigerator's model number to check it against our EBR87463764 compatibility records. Include the suffix if your plate carries one, because on this platform it decides the answer. Not found? Use the buttons below to reach our team directly.
Aggregated listings routinely publish the model stem and drop the suffix after it, which here removes the deciding character. The applied white label carries all eleven characters of the assembly actually fitted. Click the image to zoom in.
Which LG Model Codes Are Published Against the EBR87463764?
Independent parts records publish this number against five full model codes on two stems: GM-L268NKSM and GM-L268NSSM ending in ASBCNA2 and ASTCNA2, and GR-L268NSSM and GR-L268NKSM ending in ASTCNAA, ASTCNAB and ASBCNAA. A second record adds the United States cabinet LFXS26973S without a suffix.
Documented Fitment, Confirm Against Your Label
Two points are worth spelling out. First, this is the only assembly in its run published under both the GM and the GR stem, so a search that assumes one naming stream misses half its fitment. Second, the LFXS26973S entry is genuinely contested: one record names that cabinet here without a production suffix, while another assigns the same cabinet with an 02 production suffix to a neighbouring assembly. We list it because a record supports it and flag it because a record disagrees. If your plate reads LFXS26973S, do not order on the model code alone. Photograph the applied label on your board and send it over, and we will read it with you. No verifiable Kenmore code appeared against this number in any record we reached, so none is listed.
How Is the EBR87463764 Restored to Spec? The FailSafe Precision Protocol
Every EBR87463764 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 EBR87463764 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.
EBR87463764 Specifications and Cross-Reference Part Numbers
Records catalogue the EBR87463764 as a main PCB assembly and carry the references PS16621828 and EAP16621828 against it, together with an LG internal number in the 4983 series. That internal number is the trap on this platform, because the same four digit reference is also printed against a neighbouring assembly serving the same cabinets.
| Manufacturer part number | EBR87463764. Catalogued through LG parts channels under the assembly name PCB Assembly Main, and described in independent parts records as the refrigerator main control board |
| Board type | Main control board. Three separate parts records and our own product record all describe it in those terms. It is not a display assembly, not an ice maker board, and not a compressor inverter module |
| What it controls | Sensor inputs, cooling calls and compressor operation, evaporator and condenser fans, defrost scheduling, the ice compartment and water path, and communication with the door panel |
| Platform served | LG's L268 cabinet, published under GM-L268N designations on one stem and GR-L268N designations on the other, with one record additionally naming the United States LFXS26973S |
| Cross references | PS16621828 and EAP16621828 are the pair recorded against this number, with a FIX and an OEM series equivalent alongside them and the LG internal reference 4983826. Vendor stock codes in the ALG and PD series also appear, but those identify a seller's shelf rather than the part, so never buy from one |
| The shared internal number | That same 4983826 reference appears against a neighbouring assembly that serves overlapping L268 cabinets. Two distinct boards therefore answer to one LG internal number, which means matching that number proves nothing about which assembly you need. The PS and EAP references do separate the two; the internal one does not |
| The AP series | No AP reference appeared against this number in any record we reached. Two of its immediate neighbours do carry one, so an absence here is a gap in aftermarket indexing rather than evidence of anything about the part. Shop by the manufacturer number and the label |
| Supply status | Three independent records list this number as currently supplied under its own identity, with no supersession recorded in either direction. Worth noting because one neighbouring assembly covering overlapping cabinets is listed on an extended restocking window of several weeks |
| Sibling caution | Assemblies in the EBR874637 group are distinct boards with their own model lists and references. Sharing the first eight characters proves nothing about fitment, and three of them answer to L268 model stems |
| APU status | FailSafe Certified, 1-year warranty (registration required), same-day shipping* |
Is an EBR87463764 a Sensible Spend on an L268 Cabinet?
Once the sensors, fans, defrost hardware and ice components have been cleared and this assembly is genuinely at fault, an EBR87463764 is normally the least expensive way back to a working refrigerator, because the appliance around it is a full size French door cabinet costing many times more to replace.
What your options typically cost
What Undoes This Repair After the Right Part Has Arrived?
Four things undo an EBR87463764 repair: buying against a model stem with the suffix ignored, trusting a shared internal reference number as proof of fitment, leaving the sensor or defrost fault that caused the original complaint in place, and judging the result before the cabinet has had time to pull down.
Never buy an L268 board on the stem alone
A listing that shows GR-L268NSSM and stops there has published the half of the code that decides nothing. Three assemblies answer to L268 stems and the suffix separates them. A board bought this way often mounts perfectly and then runs the cabinet strangely, which is the signature of exactly this error.
Do not treat the internal reference number as a fitment check
The four digit LG internal number carried against this assembly is also carried against a neighbouring one that serves overlapping cabinets. On many boards a cross reference works as a useful second opinion. Here that particular number cannot tell the two apart, so leaning on it produces false confidence rather than a check.
Go back to the sensors before blaming the replacement
A sensor stuck open or short hands the new assembly the same impossible value it handed the old one, and the refrigerator behaves precisely as it did before the work started. Nothing on this list sends more sound boards back to us.
Return every harness to the header it came off
Neighbouring connectors on this assembly are close 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 it.
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 Less Expensive Parts Impersonate This Fault?
Parts capable of impersonating an EBR87463764 fault include the compartment sensors, the defrost heater with its thermal fuse and defrost sensor, the evaporator and condenser fan motors, the ice compartment fan and ice maker assembly, and the door display together with the loom that flexes at the hinge.

EBR87463764 LG Refrigerator Main Control Board, Frequently Asked Questions
These answers cover how the suffix separates this assembly from its neighbours, why the same number appears under two model stems, what the shared LG internal reference does and does not prove, whether the LFXS26973S belongs here, whether the number is still supplied, and what a silent L268 cabinet is really reporting.
How do I tell the EBR87463764 apart from the other L268 boards?
By the destination suffix on your rating plate, read all the way to its final character. Published records put GR-L268NSSM and GR-L268NKSM cabinets ending ASTCNAA, ASTCNAB and ASBCNAA against this number, while the same two stems ending ASTCNA2 and ASBCNA2 belong to two different assemblies entirely. Nothing earlier in the code separates them, so a listing that shows the stem and drops the suffix has removed the only published discriminator. Read the suffix, then confirm against the label on your existing board before you order.
Why does this number appear under both GM-L268N and GR-L268N model codes?
Because LG publishes this cabinet in two naming streams and this assembly is documented in both. It is the only number in its run that spans them. The practical consequence is that the suffix rule works inside a stream rather than across the pair: on a GM stem the suffixes recorded here end ASBCNA2 and ASTCNA2, while on a GR stem a suffix ending in 2 points at a different board and the letters A and B point here. Read the prefix and the suffix as one unit, never the suffix on its own.
My old board carries the LG reference 4983826. Does that confirm this part?
No, and this is the trap on this platform. That four digit internal reference is published against a neighbouring assembly as well as against this one, so two distinct boards share it. On many LG families an internal or aftermarket number works as a genuine second opinion alongside the label. Here that particular reference cannot separate the two candidates, and relying on it produces confidence rather than proof. The PS16621828 and EAP16621828 references do belong to this number specifically, and the applied label remains the deciding document.
My rating plate reads LFXS26973S. Is the EBR87463764 my board?
That one is genuinely contested and we would rather say so than guess. One parts record names the LFXS26973S against this number without a production suffix. A different record assigns the same cabinet, carried with an 02 production suffix, to a neighbouring assembly instead. Both records are otherwise consistent, so this is not a case of one being obviously wrong. If your plate reads LFXS26973S, do not order on the model code. Photograph the applied label on the board in your refrigerator and send it to us, and we will read it with you before anything ships.
Is there an AP number for the EBR87463764?
None appeared against this number in any record we were able to reach, although PS16621828 and EAP16621828 are both published for it along with equivalents in two other series. Two of its immediate neighbours do carry AP references, which makes this a gap in aftermarket indexing rather than anything meaningful about the part. If you are shopping with an AP number in hand, treat it as a lead and confirm the manufacturer number on the label first.
Is the EBR87463764 discontinued or superseded?
The records we consulted list it as currently supplied under its own number, with no supersession recorded in either direction and no replacement offered. Three independent records showed it available at the time of writing. That is a better position than one of its neighbours occupies, since an assembly covering overlapping L268 cabinets sits on a restocking window measured in weeks. None of that changes which board you should buy, only how quickly a wrong order could be put right.
My L268 refrigerator is completely silent. Is that enough to condemn the board?
On its own, no. Silence is equally consistent with cabinet logic that has stopped issuing cooling calls and with a compressor circuit that will not start, and from the kitchen the two are indistinguishable. Listen at the machine compartment and note which you hear: repeated start attempts that fade out, or no attempt whatsoever. Prove the outlet, inspect the harness feeding that compartment, and eliminate the sensors and fans. Read your paperwork too, because the compressor and sealed system on LG refrigerators of this generation often carry longer coverage than the rest of the appliance.
