Hello,
I have a 14 month old Whirlpool GX5FHDXVY04 that has recently started accumulating significant frost on the coils. I am trying to troubleshoot the issue and have used the control panel service tests to determine the thermistors in both the freezer and fresh food panels are OK. We did a forced defrost using the control panel and water started dripping from the coils - so I believe the defrost heater is working. However, the response from the service test on the defrost heater/thermostat is hard to decipher. It showed as Shorted/Closed. Can anyone help me know if that is the expected response? Also, does anyone have the service manual guide for this model? The wiring diagram would be much appreciated. It sounds like this model turns on the defrost based on compressor run time - so what could cause the defrost cycle not to start? Any advice would be appreciated - and a service guide/wiring diagram if you have it?
Thanks,
Andy
