Questions & Answers

For Ge Board Asm Main Control (Part Number: OEM21564309)

1 Answer

Greg, The display operates on 12 VDC supplied from the J4 connector on the "motherboard" on the back of the refrigerator{J4 connector, across brown and red wires should read 12 VDC). You can also lower/remove the display assembly and check for the 12 VDC across the red and brown wires. No voltage would indicate no power from the motherboard WR55X10942C Control Board. If the voltage is present, you'll need the WR55X10522 PWB Assembly Display. Thanks,

Rich, this main control board [WR55X10942P] is correct for your model. As controls are updated and revised, they become usable in multiple appliances and may have an extra connector for additional parts that may be found on another model.

Bill for Model Number GSS25WGSBWW

I just replaced # AP3861346 Interface Display Asm Wh and it did not solve my problem. The ice maker continues to make ice as normal. When I press the push tabs the lights work but the water solenoid and auger motor will not energize. I get no drinking water or ice. The micro switch attached to the paddle has continuity and the solenoid that operates the flapper works when the paddle is pushed. I operated the auger Assy. solenoid by hand and goes up and down freely. The auger motor is not bound up. Whatever the problem is it just affects the dispenser water valve and the auger motor. This problem was intermittent at first and then just quit altogether. Thanks Bill

Bill, There is a wire harness that runs out the bottom of the door. Remove the kick-plate and give each wire a tug test to make sure they are still intact. If no issues aree found there then the main control needs to be checked to see if voltage is supplied when the paddle is depressed. Test points for auger motor on main control are J7-1 [beige wire] to J7-9 orange wire. Water dispenser is J7-3 [silver wire to the same orange wire. And you are looking for 120 vac.

Bill, you may want to check the micro switch WR23X10783 in the dispenser assembly. When in the normal state, there should not be continuity, and when the button on the switch is engaged you should be able to read continuity between the two terminals. If the micro switch tests good, then most likely the display board WR55X10521 would be the issue.

Gordon, control [WR55X10942P] is the direct replacement for the original board WR55X10037. You may want to check to ensure that the thermistors are reading appropriately. If either of the freezer thermistors [WR55X10025] are not reading the appropriate temperature (more than likely the one that would have failed would have been in the lower portion of the freezer) then it would certainly cause this issue.

Andrew, this is an indication that the unit is in a self diagnostics. To exit the self diagnostics, unplug the refrigerator for 10 seconds and then plug it back in. This will stop the self diagnostics and the unit should run properly by that point.

Jesse, This issue will most likely be caused by a faulty main control board that is causing the display to not operate.

Anita, You will want to test the black and orange wires at your compressor for voltage [120 vac]. If you don't have voltage your control needs replaced. If the voltage is present and compressor runs then check the coils in the freezer for a frost pattern. No frost pattern then you have a sealed system issue or compressor not pumping and you would need a certified refrigeration technician to finish the repair.
