Stephen for Model Number TX21VW MFG NO P1315905WW Had a issue of fridge and freezer intermitently warming up cleaned condensor coils and it started working fine again then a week or 2 later it started giving me problem I checked the defrost circuit and when I moved the defrost thermostat it started working again so I replaced it. Then it started working yet again had the temps all th way to 7 both fridge and freezer. When I put 4 ice cub trays in would freeze them fine tried 6 and it took forever and temp raised up again. now the temp is raising again the evaporator and condenser fan are on but the compressor was not turning on. I turned the defrost timer into and out of defrost and still didn't kick on. Then I moved the temp controls fridge didnt turn fans off but the freezer turned fans off and on. But the compressor still didn't turn on it turned on after about 5 mins. I didn't hear the relay kick in. Turned the defrost timer in and out of defrost again turned compressor and fans off when came out turned fans on but not compressor can. The defrost timer turn the fans on and not the compressor? Or would it be the run or start relays? Do those just pertain to the compressor? Or can it be a issue with the temp sensors? Not reading correctly. Do you have wiring schematics anyplace to run down the power output from the temp controls defrost timers to compseer or relays? I am a mechanic and can check the stuff if I have the schematics unless you have some ideas. Unless I have more info I do not know what to check next. ty
Answer Stephen, This issue sounds more like a start relay that has is not operating properly. When the condenser fan motor is running but the compressor is not then you would check for 120 vac going to the compressor. If there is 120 vac then the most likely cause is the relay. Unfortunately we do not have a wiring diagram for this model. Read More... Answered by AppliancePartsPros.com | Monday, September 16, 2013
