How to Fix / Troubleshooting
Steps:
- Clean filter and vents: Ensure all air inlets and outlets are clear and the filter is clean.
- Check fan operation: Confirm the fan runs at full speed and does not stop before the compressor. Replace the fan motor assembly if it is slow or intermittent.
- Ventilation: Provide at least 12 inches of clearance around the unit and avoid enclosed spaces.
- Monitor behavior: If the compressor becomes very hot and shuts off, the internal overload may be tripping. This can indicate a failing compressor or low voltage; professional diagnosis is recommended.
