Carrier heat pumps are electric furnaces. If the internal fuse is burnt out, the heat pump won't run. The Carrier heat pump can be reset after the fuse is replaced to allow the heat pump to resume normal functioning. Interruptions in the power supply to the Carrier heat pump may create the need to reset the heat pump. Resetting the heat pump requires only a few minutes.


Step 1

Check the fuse that is located near the compressor of the Carrier heat pump. If there has been a power failure or a power surge the fuse may have blown.

Turn off the circuit breaker that services the heat pump.

Reset the circuit breaker to restore power.
