About the Defrost Thermostat
As the outdoor temperatures get colder, the outdoor coils can start to freeze up more often. When the coils frost up, a defrost control board or thermostat will energize a reversing valve to divert the warmer refrigerant from the indoor coil to help melt the excess frost from the outdoor coil. If the defrost thermostat is defective, the frost on the outdoor coils may be unable to melt. To determine if the defrost thermostat is defective, use a multimeter to test it for continuity. If the defrost thermostat does not have continuity when it reaches the low temperature of its operating range, replace it.
