Questions about this item

When should the defrost thermostat be replaced?

Replace the thermostat if the evaporator coils ice over or the refrigerator compartment warms up despite the compressor running.

What indicates the thermostat has reached its limit?

The thermostat opens at its calibrated temperature and stops the defrost heater; if it fails to reset, the heater stays off and frost builds up.
