Rick for Model Number GSS25PSMFBS Hi - I'm having the same problem as everyone else with my evaporator coils icing up. I read through the answers to the other questions and I can confirm that the evaporator fan is working. I also checked the defroster/heater with an ohm meter and it shows a complete circuit, but it looks bad with black and white patches across the tube. I'm not sure if that matters. I live overseas and will be in the US this summer so I need to bring back the most likely parts to fix it. What do you suggest? Should I try replacing the defroster/heater? Anything else that I should check first?
Answer Hello Rick, you'll want to test the defrost thermostat for continuity while it is inside the freezer. If both the thermostat and heater show continuity, you'll want to replace board WR55X10942C as this controls your defrost cycle. Thanks! Read More...
