12920710: What Number Do You Order By on This Whirlpool Board?
Whirlpool prints the production number on a white label attached to the board. Match every character, since a single digit off means a different board.
A later production run can ship with a slightly different label or layout. Size, connector layout and mounting points should still match the board you took out. If anything looks off, stop before installing and 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 12920710 Main Control Board?
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.
The board sits at the back of the unit, behind the rear panel. 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 12920710 and check it character by character.
Whirlpool Refrigerator Dead or Clicking: Is It the 12920710 Main Control Board?
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 has no customer-readable fault code, so diagnosis relies on the symptom pattern rather than a display error.
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 sticker number
Read the production number on the board before you open any packaging. If it matches 12920710, you have the right part.
Check for power at the control housing
Confirm voltage is reaching the back of the unit before you blame the board. No power there points to the outlet, the cord or the breaker, not the board.
Check the temperature sensors
A shorted or open sensor feeds the board bad information, and that is not the board's fault. Compare each reading against the wiring and test chart packed inside the appliance.
Defrost heater and thermal fuse
Both should pass a continuity check. Frost built up behind the panel with a good board usually traces back to one of these parts.
Start relay, overload and the fans
A struggling relay or a dragging fan motor can mimic a failing board. Check that both spin freely and that the relay is not rattling.
Once the power, the sticker, the sensors and the start and defrost components check out, the board is what is left. You need a replacement main control board, and buying the right one the first time saves a second wait. A sensor or relay that has been failing quietly for months often puts extra strain on the board driving it. Keep a spare on the shelf so a dead refrigerator becomes a short repair instead of a week without one.
How Do You Replace the 12920710 Whirlpool Main Control Board?
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 fully, then move the refrigerator away from the wall for access to the back panel.
Take out the screws holding the panel in place and set them aside.
Shoot the board with all wiring still attached before you unplug anything, so you have a map for reinstall.
Touch the metal frame first to drain static, then release each connector and lift the old board free.
Set the replacement board in place and reconnect every plug using your photo as a guide.
Replace the rear access panel and its screws, then push the refrigerator back into position.
- ✓I read the full number on the sticker and it matches 12920710
- ✓I confirmed power is reaching the control housing
- ✓I checked the temperature sensors against the tech sheet
- ✓I ruled out the defrost heater, thermal fuse and start relay
- ✓I photographed every connector before I disconnected anything
On this board it goes in as a straight swap. We have no programming step on record for this part. Give the refrigerator a few hours at a normal setting before you judge it. 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.
Whirlpool Refrigerator Still Not Cooling After You Replace the 12920710?
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.
Check the new board against your photo
Size, connector layout and mounting points should match the board you removed. Send us a photo if they do not line up.
Reseat every connector
A plug pushed back one position off can make a good board act dead. Match each one to your photo.
Go back to the temperature sensors
A sensor that was already failing hands the new board the same bad reading it gave the old one.
Confirm the ground connection
A loose or missing ground at the board housing can read as a dead board.
Give it time
Allow several hours at a normal setting before judging the result. A refrigerator does not reach temperature right away after a repair.
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 the 12920710 Live a Long Life?
Surge protection
A power outage or surge can damage the new board just as it damaged the old one. A basic surge protector on the outlet is cheap insurance.
Clean behind the unit
Dust and lint around the back panel trap heat near the control housing. Keep the area clear so air can move.
Check for moisture
A leaking water line or blocked drain can send moisture into the control area. Wipe the housing dry and watch for staining.
What Else Is Worth Checking While the 12920710 Is Exposed?
Temperature sensors Do it now
Inexpensive and already exposed once the panel is off. A bad sensor can make a good board look like it failed.
Defrost heater and thermal fuse On frost
Already accessible with the rear panel open. Replacing both now saves a second trip if either is close to failing.
Start relay and overload On clicking
Sits at the compressor and causes symptoms that mimic a failing board. Worth a quick check while things are open.
Door switches Quick check
A stuck switch can disable functions the same way a board fault does. Check that each one actuates cleanly.

What Else Do People Ask About the 12920710?
Why does searching 12920710 bring up so little?
Whirlpool has not issued a separate service number for this board, so the production number is the only one to search by. 12920710 is printed directly on the sticker attached to your old board. Match that number and you have the right part.
What ships in the box with the 12920710?
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.
A replacement board arrived that does not look like my old one. Is it wrong?
Stop before installing. Compare size, connector layout and mounting points against the board you took out. 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 12920710 need programming or setup after it is installed?
We have no programming step on record for this board. On this platform it goes in as a straight swap. Give the refrigerator a few hours before you judge it. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
My refrigerator is completely dead. Is it the board?
Check the outlet, the cord and the breaker first. If power is confirmed and nothing responds, the control board is a strong candidate.
Can I install the 12920710 myself?
Most people complete this swap in under 30 minutes with basic hand tools. Photograph every connector first so reinstall is straightforward.
