W10438707 or W11035752: Which Number Do You Order By?
Whirlpool prints the full production number on the white sticker on the board. Match every character, including any letters, before you order.
This number has been superseded, so a later board can arrive with a different connector layout or printing than the one you removed. Size, connector layout and mounting points should still line up. If they do not, send us both photos: the board that came out with all of its stickers, and the one that arrived.
This is not a universal main 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.
Which Whirlpool Refrigerators Use the W10438707?
Not listed? A missing model is not the same as incompatible. Go by the sticker on your old board, or use the check above and send us a photo.
Main control boards like this one sit inside a control box behind a rear panel near the compressor compartment, or behind a panel at the top or bottom of the unit, depending on the model. This model list is for reference only. Whirlpool may change boards between production runs, so two refrigerators 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.
Opened or installed boards may carry a restocking and retesting fee, so compare the sticker before you open the anti-static bag. Hold yours next to W10438707 and check it character by character.
Whirlpool Refrigerator Not Cooling: Is It the W10438707 or Something Else?
These checks help you rule out the common causes before you order. Only a qualified technician on site can confirm the fault in your refrigerator. Unplug the refrigerator before you take any panel off, and stop at any step you are not comfortable with.
This board does not have error codes on record, so diagnose it by symptom rather than a flashing code.
Let's verify it is the board by checking the common parts that contribute to these failures. They are inexpensive, easy to check, and ruling them out means you order once, with confidence.
Confirm the number on your sticker
Read it off the board before anything else. If it matches W10438707 exactly, or the newer W11035752, you are looking at the right part.
Check the outlet and cord
Make sure the refrigerator is actually getting power. A tripped breaker or a loose plug can look exactly like a dead board.
Test the temperature sensors
When a sensor drifts or fails, the board reacts to bad information, and that is not the board's fault. Compare its reading against the tech sheet, the wiring and test chart packed inside the appliance, before you blame the board.
Check the defrost heater and fuse
Heavy frost behind the rear panel with a good board often traces back to one of these parts instead.
Spin both fans by hand
A fan that drags or sticks works the board harder and can mimic a cooling failure on its own.
Once the power, the sticker, the sensors and the defrost parts all check out, the board is what is left. You need a replacement main control board, and you order it once. A sensor or fan that quietly failed for weeks can push the board harder than it was built for. Keep a spare on the shelf so a warm fridge becomes a short repair instead of a lost weekend of food.
How Do You Replace a Whirlpool Refrigerator Main Control Board (W10438707)?
Repair times and difficulty levels are general estimates and may vary by model, tool availability, and experience. This is provided as general guidance only and is not a substitute for professional service. Food is normally fine during a typical install, but we highly recommend moving it to a cooler with ice as a precaution - Appliance Pro USA is not responsible for lost or spoiled food.
Disconnect power at the wall. Set aside any food that might spoil during the repair.
Take off the rear access panel or control housing cover to reach the board.
Shoot a photo of every harness connector before you pull it loose.
Touch the chassis to ground yourself, release each connector, then remove the mounting screws.
Hold it by the edges and set it aside until the new board is confirmed working.
Set it in place and reconnect each harness to the spot shown in your photo, then replace the screws.
- ✓I photographed my sticker and matched every character against W10438707 or W11035752
- ✓I checked the outlet and cord before suspecting the board
- ✓I tested the temperature sensors and they read in range
- ✓I checked the defrost heater and fuse and both are good
- ✓I spun both fans by hand and neither one drags
On this board, it goes in as a straight swap. Reconnect each harness to the position it came from and there is nothing to program afterward. Give the refrigerator a few hours at a normal setting before you judge the result. The 5-mil nitrile gloves in the box give grip and some protection, but they are not cut-proof. Hold the board by its edges and mind the sheet-metal edges of the cover.
Why Is Your Whirlpool Refrigerator Still Not Cooling After Installing the W10438707?
Clicks and relay sounds are normal. The compressor may stay off for several minutes as a protection delay.
Fans run, compressor hums, and cold air shows up in the freezer first.
Both sections reach near set temperature. Do not load warm groceries before this.
Temperatures stabilize and the ice maker resumes. Now decide whether anything is wrong.
Once power is back on, the board compartment is live. Do not reach into it or reseat a plug with the refrigerator plugged in. Unplug first, every time.
Compare the new board to your photo
Line it up against the photo you took before removal. Size, connector layout and mounting points should match.
Recheck the ground connection
A loose or skipped ground can make a good board act dead. Make sure it sits the way the old one did.
Go back to the temperature sensors
A sensor stuck out of range feeds the new board the same bad reading it gave the old one.
Reseat every harness connector
A connector pushed in one position off can look exactly like a dead board. Match each one to your photo.
Still stuck? Contact us before you return anything
Give the refrigerator a few hours at a normal setting, then reach out with the symptom and your photos. Troubleshooting is free.
The troubleshooting steps above are general guidance only and may not apply to every model or situation. If you are unable to resolve the issue after following these steps, we recommend contacting our team or consulting a qualified appliance technician before taking further action.
How Do You Help Your New W10438707 Control Board Last?
Surge protection
A power outage or a lightning strike sends a spike straight through the board. Repeated short outages wear on it more than one long one.
Clean the condenser coil
A dusty coil makes the compressor and fans run longer and hotter, and the board runs hot right along with them.
Check the door seals and drain
A blocked drain or a weak door seal lets moisture reach the control housing. Wipe the area dry and look for staining before you close it up.
Which Parts Are Worth Replacing While the Refrigerator Is Open?
Temperature sensors Do it now
Inexpensive and sitting behind the same access panel. A sensor near the end of its life can make a good board look like the problem.
Defrost heater and fuse On frost
Already exposed if you are working near the back panel. Worth a look if frost keeps building up.
Door gaskets If worn
A loose seal lets warm air in and makes the system run longer than it should.
Evaporator and condenser fans If noisy
A fan with a failing bearing runs hot and makes the new board work harder than it needs to.

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. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.

What Else Do People Ask About the W10438707?
Why does searching W10438707 turn up limited results?
Whirlpool has moved current production to the W11035752 number, so many searches turn up more hits under that one. A parts distributor still lists the original as a special-order number, WPW10438707. Match the number on your own sticker rather than relying on search results.
What ships in the box with the W10438707?
The board sealed in an anti-static bag, the Quick Start Guide, a pair of 5-mil nitrile install gloves, and the warranty registration card.
My replacement board looks different from the one I took out. Is it wrong?
Stop before you install it. Compare size, connector layout and mounting points against the board you removed. If anything is different, send us a photo of the board you removed with all of its stickers and a photo of the one that arrived.
I ordered the wrong board. What now?
Leave the bag sealed and contact us first. An exchange is the fastest path. Opened or installed boards may carry a restocking fee.
Does the W10438707 need programming or setup after it is installed?
No programming is needed. It goes in as a straight swap, so power it up and give the refrigerator a few hours before you judge the result. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
My model is not on the reported list. Will the W10438707 still fit?
Ten models are reported for this board so far, across Whirlpool, Kenmore, Maytag and Amana. If yours is not listed, match the number on your own sticker before you order, since that is the final word on fit.
My refrigerator still runs warm after the new board is installed. What should I check?
Go back to the sensors, the ground connection and every harness plug before you assume the new board is bad. A loose connector or a failed sensor can make a good board look faulty.
