Most AC repairs should be done by a licensed HVAC contractor, but there are some great DIY jobs that you can probably do. Some jobs can be done without any power tools or special supplies. One of the best DIY jobs is to clean the condenser fan and motor. These simple checkups could be very easy, or they could reveal that there is something seriously wrong with your unit. This article explains how to safely work on your condenser fan and motor.
Before You Begin
The condenser is the unit that is right on the side of your building. The fan is usually at the top of the unit, so it is easy to access. Before you do any work, turn off your AC (at the thermostat) and cut the power to the condenser unit (at the disconnect box). Once the power is off, you can access the fan and motor.
Accessing the Motor
Most units have a top-mounted motor. That means that the motor is above the fan. These are usually the easiest to work on, but also the most likely to be damaged, because they are more exposed to the elements. First, you need to remove the bird guard at the top of the unit. You will definitely need a power drill to remove the screws. Once the guard is off, you also need to remove the top plate of the motor compartment. You don't want to actually mess with anything inside the small compartment unless you are an electrician. But, you can vacuum it out and look for problems. For instance, if any of the rubber coating on the wiring looks melted or burnt, you might need to invest in a new motor. Changing a motor is a little complicated and should be done by professionals. However, simply cleaning out the compartment can help ensure normal operation.
Cleaning the Fan and Rest of the Unit
Reattach the motor access plate and clean off the rest of the fan. By wiping down the columns and fan blades, you can help prevent rusting. You can also make sure that the column section between the fan and the motor is clean and well greased. Dirt or rust in this section can be a sign of water buildup in the motor. If this is the case, you might want to consider sealing the edges of the access plate with an exterior silicone caulk. This will prevent water damage to the fan motor.
