How do I turn my heat pump into defrost mode?
How to Defrost a Heat Pump
- Turn the heat pump off at the circuit breaker.

The unit is not defrosting. If the unit is not defrosting, ice can build up in a hurry. Defrost issues can be caused by faulty relays, controls, or sensors. There could also be a problem with the reverse valve that switches the unit from heat to air conditioning mode.
How do I know if my heat pump is defrosting?
Checking the Defrost Sensor
- Remove power from the condenser.
- Find and remove the defrost sensor from the condenser and unplug it from the control board.
- Place the sensor in a container of ice water and using your multimeter, ohm across the terminals, the sensor should read zero ohms (closed).
At what temperature does a heat pump go into defrost mode?
The defrost cycle is activated when the temperature of the outdoor coil drops below 32 degrees. At this temperature, frost can form on the coil, which can cause damage if it builds up. This is where the defrost cycle comes in. Your heat pump will switch to cooling mode to warm up the coil and melt the ice.

How long is defrost mode on heat pump?
about 10 minutes
If the outdoor temperatures have been freezing for some time, expect the heat pump defrost cycle to begin. The unit will cease blowing warm air into your home during defrosting which may cause you to hear a humming sound. The defrost cycle typically lasts about 10 minutes.
