John for Model Number PLHS269ZCB3 My side by side fridge will not get cold except at the bottom of the freezer. There was heavy 'snow' covering the lower back panel which I removed. My evaporator coils are iced over and the fan is not working. I removed the fan and plugged it into the wall and it works. The light switch seems to function normally. The icemaker will not attempt to make ice and the tray is dry although water is at the dispenser. Can you tell me where the defrost timer is on this model? I don't see anything behind the kick panel.
Answer Hi John. You are experiencing a normal defrost failure. The defrost circuit power comes from the Adc board part # 5303918476. It will send the 120 vac to the defrost thermostat which closes at 14° or colder, it is part # 5303918214. If it remains open (very common failure) then the defrost heater part # 5303918255 cannot get the power to defrost the coils every 6-1/2 hrs approx. for 25 minutes. Thank You. Read More...
