Homeowners can troubleshoot a Trane heat pump by checking the fuses and switches on the circuit breaker, resetting the thermostat and checking the gas valve shutoff to ensure it is operational. Routine maintenance, such as cleaning the coils and replacing filters, may help resolve heat pump problems.
If the heat pump is not kicking on or turning on and off frequently, homeowners can troubleshoot the Tran unit by inspecting the thermostat. The thermostat may be wired improperly, set to the wrong heat setting or installed incorrectly. If a new thermostat was recently installed, homeowners can check to see if the thermostat type is a correct match for the heat pump.
Electrical problems within the home can cause a heat pump to malfunction. Homeowners should check circuit breakers to ensure the heat pump is receiving power. Most heat pumps feature two circuit breakers that provide power to the heat pump condenser and the air handler. If these circuits have tripped, the heat pump shuts off. Reset any tripped breakers by turning the switch off and then back to on. Troubleshooting may also require an inspection of the electrical cords attached to the unit. Inspect the cords for damage and test the outlet to see if power is provided to the unit.
