About the Temperature Sensor

A temperature sensor monitors the temperature of the outdoor coils. If the coils begin to frost over, the sensor will alert the defrost control to allow power to energize a reversing valve to divert the warmer refrigerant from the indoor coil to the help mel the excess frost from the outdoor coil. If the temperature sensor is defective, the defrost system will not be alerted to the excess frost.
