What to Do When Your Condenser Fan Motor Stops Working

If you have an HVAC system at home, you may have encountered issues with the condenser fan motor. The condenser fan motor is responsible for blowing air over the condenser coil, which cools the refrigerant that flows through the system. When the condenser fan motor stops working, your HVAC system may not function properly, and your home may become uncomfortable. In this article, we will discuss what you can do when your condenser fan motor stops working.

1. Understand the Symptoms of a Faulty Condenser Fan Motor

Before you can take action, you need to identify the signs of a faulty condenser fan motor. These include:

• Warm air blowing from the vents

• Loud noises coming from the condenser unit

• The outdoor unit is not running

• The outdoor unit is running, but the fan is not spinning

• The outdoor unit is running, but the fan is spinning slowly

2. Check the Power Supply

If your condenser fan motor has stopped working, the first thing you should do is check the power supply. Make sure that the circuit breaker and the disconnect switch are in the "on" position. If they are not, turn them on and see if the unit starts running again.

3. Inspect the Capacitor

If the power supply is not the issue, the next thing you should do is inspect the capacitor. The capacitor stores energy and provides the electrical current that starts the motor. If the capacitor is faulty, the motor may not start or may start but run poorly. You can check the capacitor using a multimeter or have a professional inspect it.

4. Check the Motor

If the capacitor is not the issue, you should inspect the motor. Check for any visible signs of damage, such as burned wires or a seized bearing. You can also test the motor's windings with a multimeter. If the motor is damaged, you will need to replace it.

5. Replace the Fan Motor

If you have determined that the motor is faulty, you will need to replace it. You can either do this yourself or hire a professional. Make sure to purchase a motor that is compatible with your HVAC system.

6. Preventative Maintenance

To prevent future issues with your condenser fan motor, you should perform preventative maintenance on your HVAC system. This includes:

• Regularly cleaning and replacing air filters

• Cleaning the condenser coil

• Inspecting and cleaning the evaporator coil

• Checking and replacing the refrigerant

Conclusion

When your condenser fan motor stops working, it can be frustrating and uncomfortable. However, by following the steps outlined in this article, you can identify the issue and take the necessary steps to fix it. Remember to always prioritize safety when working on your HVAC system, and don't hesitate to contact a professional if you are unsure.
