Common Symptoms of a Faulty Fan

• Low Pressure (LP) Alarms: Reduced airflow across the evaporator prevents heat exchange, causing the refrigerant circuit to freeze or pressure to drop, which trips an LP alarm.

• Worn Motor Bearings: High-pitched squeal, grinding noise, or heavy vibration coming from the top fan compartment.

• No Fan Operation / Tripped Mains: Internal motor failure or cable wear-through causing short circuits and tripping main electrical breakers.

• Air Filter Warning / Low Airflow: Insufficient rotation despite clean air filter elements.

Check the part number, electrical connector, mounting arrangement and fan assembly against your existing part before ordering. Fan faults should be confirmed through appropriate diagnostics. Installation should be carried out by a suitably qualified professional.
