What to do if FHP Heat Pump has blown fuse?
If the FHP Heat Pump has a blown fuse, replace the fuse or reset the circuit breaker. Also, verify that you are using the correct type of fuse.
Why FHP GO072 voltage supply low?
If the voltage supply to your FHP Heat Pump is low (below the minimum specified on the unit's data plate), contact your local power company for assistance.
What to do if FHP Heat Pump refrigerant charge low?
If the refrigerant charge in your FHP Heat Pump is low, check for any refrigerant leaks. If you find any, repair them, then evacuate the system and recharge it with the factory-recommended amount of refrigerant.
How to fix broken wires in FHP GO072 Heat Pump?
If your FHP Heat Pump has broken or loose wires, replace or tighten the wires to ensure proper electrical connections.
What to do if FHP Heat Pump compressor motor grounded?
If the compressor motor in your FHP Heat Pump is grounded (internal winding grounded to the compressor shell), replace the compressor. If the compressor experienced a burnout, install a suction filter dryer as well.
How to troubleshoot thermostat issues in FHP GO072?
If your FHP Heat Pump's thermostat is not working, set the fan to 'ON' to see if the fan runs. Then, set the thermostat to 'COOL' at the lowest temperature and check if the unit runs in cooling mode. After that, set it to 'HEAT' at the highest temperature to see if it heats. If the blower or compressor doesn't run in all three cases, check the thermostat wiring and ensure 24 volts are available on the condensing section low voltage terminal strip between 'R' and 'C', 'Y' and 'C', and 'O' and 'C'. For blower issues, verify 24 volts between terminals 'G' and 'C' in the air handler. Replace the thermostat if it's defective, and also check its settings, calibration, and wiring.
What to do if FHP GO072 compressor windings open?
If the compressor windings are open on your FHP Heat Pump, allow the compressor to cool down, then check the continuity of the windings. If they are indeed open, the compressor needs to be replaced.

If your FHP Heat Pump is overcharged with refrigerant, reclaim the excess refrigerant, evacuate the system, and recharge it with the factory-recommended amount.
What causes high pressure in FHP GO072 Heat Pump?
If your FHP Heat Pump is experiencing high pressure, first check for a defective or improperly calibrated high-pressure switch. In cooling mode, ensure adequate airflow by checking for an inoperative blower, clogged filter, or restrictions in the ductwork, and make sure the entering air temperature isn't too cold.
