Guest for Model Number ED20PKXAN00 Is there a defrost cycle control circuit card in this side by side refrigerator? Problem started when I opened the freezer and refrigerator doors and the lights didn't come on. I have already replaced the defrost timer in the ceiling of the refrigerator side. No difference. I'm being told by local appliance repair that I need to replace either the defrost element or the defrost temperature sensor. That there is no circuit card in this unit. Thanks
Answer Hello, You will have a defrost heater and a defrost thermostat. Sensors are not used unless there is an electronic control board for the defrost circuit. If there is a defrost timer, it is an analog circuit. These have a calrod type heater WP2161322 and, while they do fail, the defrost thermostat WPW10225581 is much more common to fail. Read More...
