How to Fix / Troubleshooting
Safety first: Turn off power before thawing ice and inspecting components.
- Step 1 – Thaw completely: Turn system OFF and allow all ice to melt. Do not chip ice with sharp tools.
- Step 2 – Check fan operation: Ensure the appropriate fan (indoor for evaporator, outdoor for condenser) runs at full speed when system is on.
- Step 3 – Airflow and filters: Replace filters and ensure all registers are open. Clean coils thoroughly.
- Step 4 – Technician checks: If freezing recurs, a technician should check refrigerant charge, fan motor performance, and coil temperature sensors.
