What Is the WR55X10942 GE Refrigerator Main Control Board Replacement?
The WR55X10942 is the main control board for GE refrigerators, mounted behind the rear access panel where it manages the compressor, condenser and evaporator fans, defrost cycle, and temperature regulation for both the fresh food and freezer sections. This replacement control board restores full electronic control of the cooling system when the original unit fails. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
WR55X10942 was one of several original production numbers GE used for this board before consolidating them into the current service replacement, WR55X10942C, also cross-referenced as WR55X10942P. If your old board carries any of these three numbers, it is the same board and this unit is a correct match.
What Does the WR55X10942 Fix on a GE Refrigerator?
This board is the usual fix for the following complaints:
- Refrigerator or freezer not cooling, or not starting at all
- Fridge or freezer running warmer than it should
- Fridge or freezer running colder than it should
- Freezer not defrosting properly, with frost building up inside
- Clicking or unusual noise coming from behind the rear panel
- Ice maker not making ice, or the dispenser not working
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 ordering, check the sticker on your original board rather than just the refrigerator's model number. Unplug the fridge, pull it away from the wall, and remove the rear access panel to find it. A white or silver label reading WR55X10942, WR55X10942C, or WR55X10942P confirms this is your board. Your GE refrigerator part number is on the sticker on the original board - look for the WR55-, 200D-, or WR49- prefix.
Not sure? Send us a photo of your board and its sticker before you order and we'll verify it for free - same business day.
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.
Also reported to fit: DSD26DHWABG, GSS25WSTISS, GSS25SGRBSS, HSS22IFPACC, PSW26SGPA, GSS25WSTASS. This is general reference material - confirm by the part number on your board's sticker before ordering.
This model list is for reference only. GE 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 electronic brain of the refrigerator's cooling system. It reads input from the temperature sensors and controls, then switches power to the compressor and fans to keep both compartments at the set temperature. It also runs the defrost cycle on a schedule, cutting in the defrost heater at the right intervals to keep the evaporator coil clear of frost. When it fails or misreads a signal, the whole cooling system can stall, run erratically, or stop responding to the controls entirely.
Common GE Refrigerator Error Codes
If your GE refrigerator is displaying an error code, the table below describes what it typically indicates. These are general GE codes and can vary by your exact model, so use this as a general guide. Codes marked ★ are 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.
| Code |
What It Means |
| ★ HRS |
Main control board failure - system crashed or stuck in defrost. Most severe GE error |
| ★ CC |
Cooling / compressor circuit fault - board cannot communicate with compressor |
| ★ EC / E0 |
Communication error between main control board and user interface |
| ★ E4 / Er |
Defrost system error or temperature sensor fault - board-controlled cycle |
| FF |
Freezer fan failure or freezer temperature too high for 2+ hours |
| dE / DF |
Defrost system not operating properly in last 24 hours (dE) or no defrost circuit current in 48 hours (DF) |
| E2 / E3 |
Evaporator fan (E2) or condenser fan (E3) communication error |
| CI |
Ice maker fault - check for jammed ice, water supply, or ice maker assembly issue |
| PF |
Power failure detected - press System Check button to clear. Not a board fault |
| tC / tF |
Turbo Cool / Turbo Freeze active - normal function modes, not error codes |
This table is general reference material. Error code definitions vary by GE (Profile, Café, standard) 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 GE Refrigerator Main Control Board
Unplug the refrigerator before you touch anything. Remove the screws holding the rear cover panel, usually with a 1/4-inch nut driver or socket, and take a photo of the wiring before you disconnect anything so reconnection is straightforward. Release the old board from its 4 to 6 plastic mounting pins with gentle pressure or a pair of needle-nose pliers, then snap the new board into place. Reconnect each plug-in connector and the ground wire in the exact positions shown in your photo, and reinstall the cover panel. Some models require cutting a jumper or green wire per the included instruction sheet depending on the serial number prefix, so check that before closing things up. Most people finish this in under 30 minutes with basic hand tools, and once it's back together, give the unit a few hours to reach temperature before judging 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 our verification stickers or holograms removed or damaged, are not eligible for warranty coverage. Damage caused by improper installation, electrical surges, or physical damage is not covered.
Returns
Returns accepted within 30 days of purchase. Items must be returned in original condition. All returns may be subject to deductions for original and return shipping fees. Restocking and retesting fees may apply to opened or installed boards - these fees are waived for exchanges, though reshipping costs and any price difference between products will apply. Boards returned with physical damage, missing components, missing or damaged hologram stickers, or signs of improper installation may not be eligible for a full refund.
Important Installation Notes
This is not a universal control board - it is a direct replacement for the part number printed on your original board. Boards that look identical can be programmed differently, so always match the number on the sticker.
Some models may require a firmware update after installation; firmware updates and configuration changes should be performed by a qualified technician. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
Installation is performed at your own risk. By installing this part yourself you assume all risk of the repair, and Appliance Pro USA is not responsible for damage to your appliance or property, lost or spoiled food, or injury occurring during or after installation. If you are not comfortable working around electrical components, have a qualified technician install this part. If there is ever an issue with the part itself, your remedy is repair, replacement, or refund under our warranty and return policies.
Even if you end up calling a pro, knowing your part number and symptoms before the tech arrives usually shortens the visit and the bill.
