Adan for Model Number WRF560SEYM00 Coils are icing up. Opened the back panel and checked for continuity on the defrost heater assembly, was working. I checked the thermistor and get a reading of 2ohms in room temperature and about 8-9 ohms in a cup of water with ice. Seems to go higher the colder the water would get. I checked both items and seems to appear in working order. What other item can cause icing up in the coils?? Please advise.
Answer Adan, If the heater and the defrost thermostat check ok then the issue would be caused by a faulty control board. The control board is located on the back of the unit and is part number W11034366. Read More... Answered by AppliancePartsPros.com | Thursday, May 28, 2015
