Brad for Model Number Whirlpool GX5SHDXVQ02 Hello, Refer just under 3 years old. Last month had a similar issue as many people writing in; temp controls no longer working: freezer too cold (-10 to -20) and refer too warm (50 -60). Called repair guy and he removed ice buildup on evaporator coil. He said the problem was due to a defective "check valve". No electrical tests of any circuits performed. Everything normal for a month, until the ice returned and temp controls no longer responding, as before. On the phone he said it was probably the "control board" and would have to order one. However, while waiting for the part, in the last day the refer began working again as normal (I realize that it did not repair itself). Now after reading other peoples comments, I'm wondering if the problem may be an "intermittent" defrost thermostat or heater? Any advise before he comes out again with a part that may not be required, or may not solve the problem? (He also has a 3 hour round-trip drive) Brad
Answer Hello Brad. If it started working again, after failure, it sounds like a bad board on the unit. Read More... Answered by AppliancePartsPros.com | Saturday, May 4, 2013
