How to Fix / Troubleshooting

Safety first: Unplug the unit before accessing internal components.

  • Step 1 – Clean and clear condenser:
    • Remove dust and debris from the condenser coil and ensure unobstructed airflow.
  • Step 2 – Verify fan operation:
    • Check that the condenser fan starts whenever the compressor runs.
    • Replace the Condenser Fan Motor if it fails to run or is very weak.
  • Step 3 – Check installation conditions:
    • Ensure the unit is not installed in a confined, unventilated space.
    • Avoid direct sunlight on portable units where possible.

If H3 recurs after these steps, the compressor may be failing internally and should be evaluated by a professional.
