What Is the W10516800 Whirlpool Refrigerator Main Control Board Replacement?
The W10516800 is the genuine OEM Whirlpool refrigerator main control board for Whirlpool refrigerators. This board manages temperature regulation, compressor operation, fan control, and defrost cycle timing. FailSafe Certified™ and backed by a 1-year warranty from Appliance Pro USA.
What Problems Does This Board Fix?
This is the main control board — the module that manages temperature regulation, compressor operation, fan control, and defrost cycle timing. When it fails, your refrigerator loses the function it controls. If your Whirlpool refrigerator is showing any of these symptoms, this board is the most likely cause.
- Refrigerator not cooling or cooling inconsistently
- Defrost cycle failures or frost buildup behind the rear panel
- Compressor or fan not cycling on correctly
- Freezer section too warm or too cold
- Unresponsive controls or error codes on the display
- Refrigerator not starting or intermittent power failures
These symptoms point to the main control board as the most likely cause — but refrigerators are complex systems, and the same symptoms can occasionally stem from a thermistor, door switch, wiring harness, or compressor issue. If a technician has identified the control board specifically, or if you've already ruled out other components, this is your part. When in doubt, a quick diagnostic by a local appliance technician before purchasing can save time and money.
How Do I Know If This Is the Right Board for My Refrigerator?
Match the part number on the sticker on your original board to W10516800. Your Whirlpool refrigerator part number is on a sticker on the board — look for the W10 or WPW10 prefix. Not sure? Contact us before purchasing and we'll verify for free — same business day.

Board Type and Function
Main Control Board — the central electronic module responsible for every primary function of your refrigerator. Cooling logic, defrost cycle timing, compressor operation, fan control, and sensor input processing all run through this board. When it fails, no individual component is at fault — the system loses its central command.
