How to Fix / Troubleshooting
Safety first: Turn off power before removing covers or cleaning internal parts.

- Inspect coil and fan: If the coil and fan wheel are covered in dust, clean them carefully with a soft brush and vacuum. For severe buildup, consider professional cleaning.
- Check fan speed: Run the unit and cycle through fan speeds. If speed does not change or remains low, the fan motor or control may be faulty.
