What Does An HVAC’s Condenser Fan Motor Do?
The HVAC system’s condenser fan motor, compressor coil, and condenser coil are all located in the outdoor condensing unit.
This unit is responsible for keeping the AC unit cool while it’s running. The condensing unit’s motor is crucial to the cooling process, as it’s what turns the fans that blow air across the condenser coil. When air blows across the condenser coil, it cools the refrigerant, transforming it from a hot gas into a liquid. If the motor itself overheats, it will stop working, and the HVAC system will have no way to cool itself, eventually causing the system to fail.
The Common Causes Of An Overheating Condenser Fan Motor
There are a few possible issues that can cause a condenser fan motor to overheat. The most common causes include:
- Worn Out Motor. Old motors may eventually give out after excessive use or lack of maintenance.
- Faulty Capacitor. A defective or malfunctioning capacitor can cause a motor to spin too slowly or stop it from turning altogether.
- Debris In Outdoor Unit. Overgrown vegetation surrounding the condensing unit, or debris that’s fallen inside it, can restrict airflow between the fans and condenser coils.
- Electrical Problems. Damaged wiring or inadequate circuits may cause a motor to stop operating altogether.
- Neglected Maintenance. Without regular maintenance performed by a professional, the condenser fan’s motor will wear out faster.
Telltale Signs Of Overheating
Condenser fan motors overheat when they reach a temperature of roughly 150 degrees Fahrenheit. Upon overheating, the motor will stop running, halting the HVAC system and potentially damaging other vital components.
The following are a few signs that your condenser fan motor may be overheating:
- The top of the outdoor unit is hot to the touch.
- A buzzing or humming sound can be heard coming from the outdoor unit.
- A strong odor emanating from the outdoor unit.
- The AC system runs but is no longer distributing cold air.
- The AC system suddenly cuts out.
If your HVAC system displays any overheated motor signs, contact the professionals at our AC repair company in Virginia immediately.
