Looking for help in fixing a problem with a WRF989SDAM03 fridge. The ice maker stopped making ice and the water dispenser stop working. If I power cycle the fridge, both will work for a while. The water dispenser will work for maybe an hour and the ice maker will work for a day. The dispenser switch always operates the ice motor so it seems good.
I ran the diagnostics on both of them and they pass. The Dispenser switch passes the diagnostic test. If I use the diagnostic code to manually operate the water valve, it will dispense water. Exit diagnostic mode and the water dispenser doesn't work. Cycle the power and both work for a while.
I'm thinking that this is a main board issue. However, that is a very expensive part to swap out as a test. I want to rule out other causes first.
I appreciate any help in trying to fix this.
Thanks,
Cary
