Ronnie for Model Number KUIS155HBL3 not sure can't seem to find it. its a kitchenaid undercounter ice maker with a smart water valve and optional waste water pump. The ice maker will make ice just fine for about 1/2 a day to maybe 2 days then the entire unit shuts down. no panel lights or ice bin light. So far the board , the ice bin thermistor and wiring harness has been replaced. the unit shows to have main power to the unit , the transformer both in and out, and power to the control board. I'm wondering if the smart valve is being told that the water level is too high and shuts the unit down completely like that. Just seems unlikely that the control lights and the bin light would go off even on a error .
Answer Hello Ronnie. You will need to check the power coming to the unit. Make sure it is correct and make sure the house breaker is not failing. Only thing left is a board issue. But if it is new, I would start with these other test first. Read More... Answered by AppliancePartsPros.com | Thursday, June 4, 2015
