How do you change the defrost timer on a heat pump?
Every 30 minutes, 60 and 90 minutes, some generic timers will boost the defrost cycle. The defrost relays turn on the compressor, switch the reversing valve of the heat pump, turn on the interior electric heating element, and stop the fan from spinning. The unit is cold.
