Frequently Asked Questions
•How do I test the defrost heater?
Disconnect the heater wires and use a multimeter set to ohms. A reading between 15-50 ohms indicates the heater is good. An open circuit (infinite resistance) means the heater is faulty and needs replacement.
•Where is the defrost thermostat located?
The defrost thermostat is typically located on the evaporator coil, usually clipped to one of the refrigerant lines. It's a small, round or rectangular component with two wires connected to it.
•How do I clear the defrost drain?
Locate the drain hole at the bottom of the evaporator trough. Use a turkey baster or a small flexible tube to flush hot water down the drain. Repeat until the drain is clear and water flows freely.
