Frequently Asked Questions

Q: What does a refrigerator defrost thermostat do?

A: The defrost thermostat monitors the temperature of the evaporator coils in your refrigerator. When coils drop to a set temperature, the thermostat opens the defrost circuit, stopping the heater from overheating and protecting the appliance during the defrost cycle.

Q: Is this bimetallic defrost thermostat compatible with my refrigerator?

A: This N13-4 2-wire bimetallic defrost thermostat is designed to fit a wide range of refrigerator models. Check your existing thermostat's specifications — particularly the temperature rating (N13-4) and electrical rating (AC 250V / 10A) — to confirm compatibility before purchasing.

Q: How do I install this replacement defrost thermostat?

A: First, unplug your refrigerator and remove any food that may spoil. Locate the existing defrost thermostat on the evaporator coils, disconnect the 2-wire connections, and remove the old unit. Clip the new bimetallic thermostat into place on the coils, reconnect the wires, and restore power. Always consult your refrigerator's service manual for model-specific guidance.

Q: What is the electrical rating of this defrost thermostat?

A: This thermostat is rated at AC 250V / 10A, making it suitable for standard residential refrigerator defrost systems.
