What to do if my Goodman Heat Pump unit will not run?
- A
  Anthony CunninghamAug 16, 2025
  If your Goodman Heat Pump doesn't run, first check the unit voltage at the contactor. If there is no voltage, check for any loose electrical connections. If the voltage is present, reset the thermostat. Also, check the contactor for 24 volts at the coil; replace the contactor if the contacts are open. Replace any blown fuses or reset tripped breakers. Check the wiring and replace the transformer if defective. Inspect the high or low pressure control (if equipped). The high pressure control opens at 610 psig, and the low pressure control opens at 22 psig. If none of the above resolves the issue, replace the compressor, remembering to wait at least 2 hours for the overload to reset.

Why is my Goodman PC Heat Pump compressor short cycling?
- H
  Hannah LeeAug 19, 2025
  If your Goodman Heat Pump's compressor cycles frequently, it could be due to a defective overload protector, in which case you should replace it and check for correct voltage. The unit might also be cycling on low pressure control, so check the refrigerant charge and airflow. Another possibility is that the high pressure switch is cutting out; in this case, check the airflow (both indoor and outdoor) and the expansion device.

What causes insufficient cooling in my Goodman PC Heat Pump?
- D
  Dakota BowmanAug 21, 2025
  Insufficient cooling in your Goodman Heat Pump can be caused by several factors. First, the unit might be improperly sized, so recalculate the load. Second, there might be improper airflow; it should be approximately 400 CFM per ton. Third, the refrigerant charge might be incorrect; charge it per the procedure attached to the unit service panel. Fourth, incorrect voltage can be a factor; at the compressor terminals, voltage must be within 10% of nameplate volts when the unit is operating.

What to do if my Goodman PC condenser fan runs, but the compressor doesn't?
- M
  Mary ReedAug 25, 2025
  If the condenser fan runs but the compressor doesn't, first check for unit voltage at the compressor and tighten all connections. If that's not the problem, wait at least 2 hours for the overload to reset; if it's still open, replace the compressor. Also, at the compressor terminals, voltage must be within 10% of nameplate volts when the unit is operating. Finally, check the capacitor; if it's defective, replace it.

Why is my Goodman PC showing high head pressure with high or normal suction?
- D
  Dillon McbrideAug 28, 2025
  High head pressure with high or normal suction in your Goodman Heat Pump can stem from several issues: * If in cooling mode, the condenser coil might be dirty; if in heating mode, the filter or indoor coil might be dirty. Clean the coil in cooling mode or the filter/indoor coil in heating mode. * The system might be overcharged, so correct the system charge. * In cooling mode, the condenser fan might not be running; in heating mode, the indoor blower might not be running. Repair or replace the fan or blower as needed.

Why is my Goodman PC Heat Pump showing registers sweat?
- L

  Registers sweat because of low airflow. To fix this, increase the speed of the blower or reduce restriction by replacing air filters.

Why is my Goodman Heat Pump showing high suction pressure?
- J
  jamesfitzgeraldSep 3, 2025
  High suction pressure in your Goodman Heat Pump may be due to an excessive load, so recheck the load calculation. Another cause could be a defective compressor, in which case you should replace it. Finally, the reversing valve might not be seating properly, requiring replacement.

Why is my Goodman PC Heat Pump showing low suction with a cool compressor and iced evaporator coil?
- C
  cliffordballardSep 6, 2025
  Low suction with a cool compressor and iced evaporator coil in your Goodman Heat Pump can arise from: * In cooling mode: low indoor airflow. In heating mode: dirty outdoor coil, defective defrost thermostat or control board, outdoor fan not running, or low refrigerant charge. Increase blower speed or reduce restriction by replacing air filters. * Low airflow: Aim for approximately 400 CFM per ton, ensure clean air filters, and open all duct outlets. * Low refrigerant charge: Properly charge the unit. * Operating in cooling mode below 65°F outdoor temperature: Install or check the low ambient control, which should be open below 65°F.

What causes high head and low suction in my Goodman PC Heat Pump?
- W
  William ThompsonSep 9, 2025
  High head and low suction in your Goodman Heat Pump is caused by a restriction in the liquid line or a non-functioning TXV. Remove the restriction or replace the TXV with the proper size.

What causes low head and high suction in my Goodman Heat Pump?
- R
  Randall ThomasSep 12, 2025
  Low head and high suction in your Goodman Heat Pump can be caused by: 1. Incorrect TXV: Replace it with the correct TXV. 2. Defective compressor valves: Replace the compressor. 3. TXV not functioning properly: Check for debris or deformation and remove debris or replace the TXV. 4. Incorrect TXV setting: Check the Super Heat.
