How to Fix / Troubleshooting
Safety: Unplug the unit before cleaning or servicing.
- Improve ventilation: Ensure at least 8–12 inches of clearance around the unit. Do not place it in a closet or tight corner.
- Clean filter and coils: Wash the air filter and vacuum dust from the condenser and evaporator coils.
- Check fan speed: Confirm the fan runs strongly on all speeds. A weak or intermittent fan can cause overheating.
- Allow cooling: Let the unit cool for 30–60 minutes and try again. If it repeatedly shuts off, the compressor or fan may be failing and require professional service.
