What Is the EBR44361503 LG Refrigerator Main Control Board Replacement?
The EBR44361503 is the main control board for LG refrigerators, mounted behind an access panel either at the rear of the unit or up near the top of the fridge compartment behind the control housing. It runs the compressor, manages defrost timing, and regulates temperature across the fridge and freezer sections. If your original board is failing, this replacement control board restores those functions. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the EBR44361503 Fix on a LG Refrigerator?
If your refrigerator is showing any of these problems, a failing control board is a likely cause.
- Refrigerator won't power on or keeps shutting off on its own
- Fridge running warm or not cooling at all
- Compressor kicking on and off with no clear pattern
- Control panel unresponsive or display completely dead
- Error or fault codes showing up on the display
- Defrost cycle not kicking in when it should
These symptoms point to the refrigerator control board as the most likely cause - but appliances are complex systems, and the same symptoms can occasionally stem from a sensor, switch, wiring harness, or motor issue. If a technician has identified the control board, or you've ruled out those components yourself, this board is your fix. When in doubt, contact us before you order - we're happy to walk you through some troubleshooting, and a photo of your board is usually all we need. A diagnosis from a local appliance technician works too.
How Do I Know If This Is the Right Board for My Refrigerator?
Before you order, pull the access panel and check the sticker on your existing board - that's the number that matters, not just the fridge's model number. Look for EBR44361503 printed on the label. If that number is on your board, this is the correct replacement. Your LG refrigerator part number is on the sticker on the original board - look for the EBR or CSP prefix.

Compatible Refrigerator Models
This board is ordered by part number, not by appliance model. Send us your full model number and a photo of your board's sticker and we will confirm fitment before you buy - same business day.
This model list is for reference only. LG may change boards between production runs, so two appliances with the same model number can use different boards. Always order by the part number printed on your original board - it is the only identifier that decides.

Board Type and Function
This board is the brain of the refrigerator's cooling system. It reads temperature signals and decides when to run the compressor, when to trigger a defrost cycle, and how to hold both compartments at the right temperature. It also manages power distribution to fans and other components tied into the cooling cycle. When it fails, the whole system loses coordination - which is why symptoms range from warm food to a dead control panel.
Common LG Refrigerator Error Codes
If your LG refrigerator is displaying an error code, the list below describes what it typically indicates. These are general LG codes and can vary by your exact model, so use this as a general guide. Codes labeled Board Related are the ones most directly associated with main control board failure. Always confirm the exact meaning in your model's owner's manual or service guide before ordering any part.
-
CO - Board Related - Communication failure between main control board and display board
-
Er CF / CF - Board Related - Condenser fan feedback signal error - board not receiving fan confirmation signal
-
22 - Board Related - Compressor relay problem - board-managed compressor circuit fault
-
dH - Board Related - Defrost cycle timed out - evaporator did not reach target temperature within 1 hour
-
Er FF - Freezer evaporator fan failure - fan not circulating cold air in freezer
-
Er rF - Refrigerator evaporator fan failure - fan not circulating air on fresh food side
-
Er FS - Freezer temperature sensor failure
-
Er rS / r2 - Refrigerator temperature sensor failure - upper (rS) or lower (r2) section
-
dS - Defrost temperature sensor short or disconnection
-
Er IF / IS / It - Ice maker fan (IF), temperature sensor (IS), or motor (It) failure
-
CH E / CL E - Refrigerant leak detected - high-side (CH E) or low-side (CL E). Requires professional service

OF F - Demo mode active - cooling disabled. Not an error. Deactivate via control panel hold sequence
This list is general reference material. Error code definitions vary by LG model series. Always confirm the exact meaning in your refrigerator's owner's manual or service guide before purchasing any part.
How to Install a LG Refrigerator Main Control Board
Unplug the refrigerator before you touch anything. Remove the screws holding the access panel and set it aside, then take a good look at how the wiring connectors are seated on the old board before pulling any of them loose - a quick photo helps here. Move the connectors over to the new board one at a time so you don't mix up the orientation. Handle the board by its edges and keep it away from static-prone surfaces while you work. Most people with basic hand tools are done in under 30 minutes. Once it's back together and plugged in, give the fridge a few hours to stabilize before you judge whether the repair worked.
Shipping
Every board is physically in stock - no backorders, no drop shipping. Orders placed before 4:00 PM EST ship the same business day. Tracking provided on every order.
Warranty
Backed by a 1-year warranty from Appliance Pro USA (registration required - the card is in the box). If the board fails due to a defect within the warranty period, we'll repair or replace it at no charge (shipping fees may apply). Warranty coverage is determined at Appliance Pro USA's discretion. Boards that have been tampered with, or with the verification seal (hologram or tamper-evident sticker) removed or damaged, are not eligible for warranty coverage. Damage caused by improper installation, electrical surges, or physical damage is not covered.
Returns
Returns are accepted within 30 days of delivery. Boards that are unopened and uninstalled, in original condition with the verification seal (hologram or tamper-evident sticker) intact, qualify for a full refund. If the board has been opened or installed, contact us before sending it back with a photo of the board you received, the reason for the return, and a photo of your original board's part-number label so we can verify fitment and approve the return. Boards returned used, altered, damaged, or with the verification seal missing may receive a partial refund in line with our return policy. Exchanges for the correct part are always available.
Not sure it's the board? Before you order, and before you return, contact us. We offer free troubleshooting help and can usually tell from a photo of your board and its symptoms whether this is the right part. Only a technician can fully diagnose your appliance.
