Possible Causes
Dirty air filter, Low airflow due to closed vents or dirty coil, Low refrigerant charge, Faulty indoor blower motor
How to Fix / Troubleshooting
Safety first: Turn off cooling at the thermostat to prevent compressor damage. You may run the fan only to help melt ice.
Steps:
- 1. Thaw the system: Set thermostat to OFF and fan to ON. Allow several hours for all ice to melt. Place towels or a pan under the air handler if in an attic.
- 2. Replace filter: Install a clean filter in the Bryant air handler or furnace.
- 3. Check vents: Open all supply and return vents to ensure proper airflow.
- 4. Inspect coil: After thawing, inspect the evaporator coil for dirt buildup and have it cleaned if necessary.
- 5. If icing recurs: A technician should check refrigerant charge and blower performance.
