Possible Causes
Dirty air filter, Restricted return or supply ducts, Low refrigerant charge, Blower motor not running at full speed
How to Fix / Troubleshooting
Safety: Turn off the cooling mode to prevent compressor damage.
- 1. Turn system OFF and fan ON: Set the thermostat to OFF and fan to ON to circulate warm air and melt the ice. This may take several hours.
- 2. Replace filter: Install a clean air filter and ensure all vents are open.
- 3. Inspect blower operation: Confirm the blower is running strongly when the fan is ON. Weak airflow suggests motor or capacitor issues.
- 4. After thawing, restart: Turn COOL back on and monitor. If icing recurs, call a technician to check refrigerant charge and coil cleanliness.
