Johnrue for Model Number PFS22SISBSS Had clicking and compressor not starting replaced the original relay and overload with wr07x10097. Worked for 3 days freeezer and fridge at correct temps then realized freezer started to ice up (never had happened) and fridge started heating up and compressor was hot to the touch. When I rechecked install of wr07x10097 realized I had not connected the ground wire back to the overload housing. Just reconnected it and am letting everything de-ice. Could this failing to have grounded the capacitor/overload have cause the malfunctions just described?
Answer Johnrue, No the ground wire not being attached would not cause the coils for the evaporator to ice up. You will want to check the defrost limiter and defrost thermostat for continuity. If they have continuity then test the defrost sensor for resistance. If they do not have continuity then the part would need replaced. If you need to test the sensor the resistance readings should be as follows, at 77 degrees resistance 5K ohms, 37 degrees resistance 14.4K ohms and at 0 degrees resistance 42.2K ohms. If outside of these readings then the sensor is bad and if this checks ok then the control board would be the issue. Read More... Answered by AppliancePartsPros.com | Wednesday, July 15, 2015
