Questions & Answers

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

1 Answer

Robert, You will want to pull the unit out and pull the drain tube off and check to make sure that it is not clogged up. This will be the most likely cause for the unit to keep freezing the water in the drain trough.

Hello Andrew, I'm sorry but this appears to be an export unit and the parts list for it will have to be looked up by an export dealership. Thank you for your patience and understanding in this matter.

Jed, For this issue it sounds likely that the cause of the fan not working and the dispenser not working would be a faulty main control board WR55X10942C.

Juan, This issue will be a defrost issue. You will need to check the defrost heater and defrost limiter to make sure that they have continuity. If there is continuity then you will need to check the defrost thermostat for resistance of 10K ohms at room temp. If this checks ok then the issue will be a faulty control board.

Steve, the evaporator fan in your refrigerator is a DC voltage fan motor WR60X10185. to determine where the issue is access the fan motor and disconnect the wire harness from the fan. Start the refrigerator and check for 8 to 12 VDC across the red and white wires in the wire harness connector. if you have the voltage the fan motor has failed. If you don't have the voltage recheck for the voltage out of the motherboard, then check the wiring to see if there's a damaged, loose or broken wire.

William, This issue would be either something not connected properly on the board or the board that was received has a defective icemaker circuit.

Fei for Model Number GSH25JSTASS

My refrigerator stopped working after a power outage. NOTHING seems to run at all except the lights inside cabinet. No light on the control display, fans don't run, compressor doesn't seem to want to start. I didn't hear any clicking sound or anything. The refrigerator is just completely dead. My guess is motherboard, but I am not sure. I visually checked the motherboard, I didn't see anything obvious (no burned marks). Could anything else cause this symptom? Thanks

1 Answer

Hello Fei, This sounds like either a harness issue or the main board WR55X10942C has failed. You will need to verify voltage to the main board. If 120Vac is getting to the board, it will be the problem.
