What Is the W10438707 Whirlpool Refrigerator Main Control Board Replacement?
The W10438707 is a replacement control board built for Whirlpool refrigerators, mounted inside a control box or housing either near the compressor compartment at the back or behind a panel at the top or bottom of the unit depending on the model. It manages cooling cycles, defrost timing, and temperature regulation so the fridge and freezer sections run the way they're supposed to. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
Whirlpool updated the production number on this board to W11035752, so if your unit shipped with that number it's the same board with a newer part number.
What Does the W10438707 Fix on a Whirlpool Refrigerator?
If your refrigerator is showing any of these problems, a failing control board is a common cause.
- Refrigerator isn't cooling or the freezer won't get cold enough
- Control panel display is blank or not responding
- Some or all of the buttons on the control panel stopped working
- Temperature readings are inconsistent or don't match actual conditions
- Frost is building up from a defrost cycle that's not running right
- Unit resets on its own or throws an error code
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?
Open the control housing or rear access panel and look for the white or silver sticker on the board itself - that's what confirms the match, not the model number printed on the fridge. If that sticker reads W10438707, W11035752, or WPW10438707, this is your board. Your Whirlpool refrigerator part number is on the sticker on the original board - look for the W10 or WPW10 prefix. This listing is for revision C - the sticker should read W10438707 Rev C. A different revision letter can be a different board, so match it.
Other part numbers used for this board: W11035752, WPW10438707. Retailers and parts catalogs list the same board under these numbers.

Reported fit is general reference material - confirm by the part number on your board's sticker before ordering.
This model list is for reference only. Whirlpool 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 the temperature sensors and tells the compressor and fans when to run, controls how often and how long the defrost heater cycles, and keeps the fridge and freezer sections at the temperatures you've set. When it fails, you'll usually see it show up as cooling problems, a dead control panel, or the unit resetting and throwing codes on its own.

How to Install a Whirlpool Refrigerator Main Control Board
Start by unplugging the refrigerator and clearing out anything perishable, since the unit will be without power for a bit. Locate the control housing or rear access panel and remove the cover to expose the board - take a photo of the wiring harness before you unplug anything so you know exactly where each connector goes back. Remove the mounting screws, swap the old board for the new one, and reconnect the harness in the same positions you photographed. Handle the new board with anti-static precautions since it's sensitive electronics. Most people finish this job in under 30 minutes with basic hand tools. Once it's buttoned back up and plugged in, give the refrigerator a few hours to settle into its cooling cycle 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.
