water dispenser Whirlpool WRF989SDAM03 Ice Maker and Water Dispenser problem

[Doc99]

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

I have changed out the HV board to correct your condition. Several times actually...

[Doc99]

Which is the HV board? Is it the power supply?

[Koi Guy]

Yes, the big board on the back of unit.

Thank you for your help and patience. You are talking about the control circuit board (in the middle section of the board area) which is the largest board? I was confused by HV.  HV to me  means high voltage which would be a power supply. 

The control circuit board is the logical culprit. Also the most expensive. I was hoping it would be something else.

I was surprised to find it cheapest at Sears $108.05. Marcone $265.54. Repair Clinic $311.70.
