How to Fix / Troubleshooting
Warning: Refrigerant circuit components should only be serviced by certified technicians.

- Inspect outdoor coil: Look for heavy frost or ice. The unit should periodically defrost; if not, see defrost-related entries.
- Clean coil and ensure airflow: Remove debris and ensure the outdoor fan is working properly.
- Mode confirmation: Verify the unit is actually in HEAT mode and not AUTO or COOL.
