Possible Causes
Dirty air filter, low indoor fan speed due to failing motor, low refrigerant charge, thermostat sensor mispositioned on coil
How to Fix / Troubleshooting
Safety: Unplug the unit and allow all ice to melt before servicing. Place towels to catch water.
Steps:
- 1. Clean filter and coil: Ensure the filter is clean and the evaporator coil is free of dust.
- 2. Check fan operation: Verify that the indoor fan runs at full speed. Replace the fan motor or capacitor if weak.
- 3. Sensor placement: Ensure the evaporator thermistor is properly clipped to the coil, not hanging in the air, so the control can detect freezing conditions.
- 4. Professional refrigerant check: If freeze-ups continue despite good airflow and sensor placement, a low refrigerant charge may be the cause. Contact a licensed technician.
