If you're looking to install an outdoor fan motor, it's important to know the basics of mounting it properly. A well-mounted outdoor fan motor not only helps improve the longevity of the motor but also helps improve the efficiency of your outdoor unit. In this article, we'll go over everything you need to know about mounting your outdoor fan motor.

Understanding Your Outdoor Fan Motor

Before you start mounting your outdoor fan motor, it's important to understand what it does and how it works. Your outdoor fan motor is responsible for blowing the hot air out of your air conditioning unit, allowing it to cool the refrigerant inside. If the motor isn't mounted properly, it can lead to inefficiencies in the cooling process, causing your AC to work harder and use more energy.

Choosing the Right Mounting Location

The first step in mounting your outdoor fan motor is choosing the right location. You'll want to select an area that's sturdy, level, and easily accessible. It's also important to keep in mind that the location should allow for proper airflow to the motor to prevent overheating.

Preparing for Installation

Once you've chosen the location, you'll need to prepare for installation. Start by turning off the power to the outdoor unit at the breaker. Then, remove the old motor by disconnecting the wires and removing any screws or bolts holding it in place. Clean the area where the motor was mounted to ensure that the new motor has a clean surface to mount to.

Mounting the New Motor

Now it's time to mount the new motor. Start by attaching the mounting bracket to the motor. Then, align the bracket with the mounting location and use screws or bolts to secure it in place. Make sure the motor is level before tightening the screws or bolts.

Wiring the New Motor

With the motor mounted, it's time to wire it. Start by attaching the ground wire to the grounding screw on the motor. Then, connect the remaining wires according to the manufacturer's instructions. Be sure to double-check all connections before turning the power back on.

Testing the Motor

Before turning the power back on, it's important to test the motor to ensure that it's running properly. You can do this by manually turning the motor with your hand to see if it spins freely. If it does, turn the power back on and observe the motor as it runs to make sure there are no unusual noises or vibrations.

Maintaining Your Outdoor Fan Motor

Once your outdoor fan motor is installed and running, it's important to maintain it properly. Regular maintenance can help improve the lifespan and efficiency of your motor. This includes cleaning the motor and blades, lubricating moving parts, and checking for any signs of wear or damage.

Common Problems with Outdoor Fan Motors

There are a few common problems that can occur with outdoor fan motors. These include:

1. Overheating

If your outdoor fan motor is overheating, it may be due to a lack of airflow. This can be caused by a dirty motor or blades, a clogged air filter, or a blocked air intake.

2. Motor Failure

Motor failure can occur due to wear and tear or electrical issues. This can lead to a complete breakdown of the motor, requiring replacement.

3. Noisy Motor

If your outdoor fan motor is making unusual noises, it may be due to loose or worn parts. This can be fixed by tightening screws or replacing damaged parts.


Mounting your outdoor fan motor is a crucial step in ensuring the longevity and efficiency of your air conditioning unit. By following these steps and properly maintaining your motor, you can help prevent common problems and ensure that your unit runs smoothly for years to come.
