Defrost Thermostat Temperature Range

This thermostat is normally closed for continuity at room temperature.

Defrost thermostat temperature range. This part should read 0 ohms in a frosty setting. This is a bimetal defrost thermostat for your refrigerator. We would advise testing the sensor on the upper left side of the evaporator for resistance as well. There is a lot of misinformation on testing the defrost thermostat.

If the temperature of the evaporator rises to 47 degrees a defrost termination thermostat will open to turn off the heater. It stops the fridge from overheating during the defrost cycle by protecting the evaporator.
