John for Model Number GSS25QGTABB A few weeks ago our ice and water dispenser quit working but we could still control the temp. Now the entire control panel does not work. I checked at the bottom of the door to see if there was a pinched or broken wire on the wiring but it appers to be ok. There is a connector in the wiring harness that has nothing plugged into to it but I could not find any empty plug. Your phone rep (Tom who was very helpful) suggested that it might be part number AP4362900 that may need to be replaced. Is there a way to check that board? Do you have any ideas or suggestions? The temperature in the fridge seems to be holding at 37 degrees. Is that part difficult to replace? Thank you very much for your assistance. Have a great 2013.
Answer John, You can check for 12 VDC at the J4 connector pin 1(black) to pin 2(red) on the dispenser board. If you have the voltage, then the dispenser board WR55X10859 has failed. No low voltage would indicate a faile main control board WR55X10942C or loose/broken wire connection. It does sound like an issue in the dispenser board, It may have a degrading circuit in the board tracers or transformer. Read More... Answered by AppliancePartsPros.com | Monday, January 14, 2013
