How to Stop the Compressor Fan from Overheating in a Central Air Conditioner Unit How to Stop the Compressor Fan from Overheating in a Central Air Conditioner Unit

What You'll Need
Canned air

A central air conditioning unit can get high heating and cooling costs in control. The central air conditioner unit can both heat and cool your home by way of an outside unit. The unit is connected to the vent system located in your home and generates cool and hot air using its compressors. The air is then pushed through the ductwork and the vents. A central AC unit is more economical to run than electric, gas and oil heat, but also cheaper than traditional air conditioners. If properly cared for, a central unit can last for years, but one key problem it can face is having the condenser overheat. When this happens, the unit can trip a circuit breaker, completely burn out its internal components and cease to cool or heat the home. Read on to learn how you can prevent this from happening.

Step 1 – Filter

All of these units have a filter somewhere in the system which is likely to be where the unit is connected. The most common area is in the basement. You will know the unit when you see it because it will be large and typically attached to the ceiling by a few brackets. The ductwork is then attached to the end. The filter is in the center of this unit.

Locate the screws on the side and remove them. The filter will slide out easily once the screws are removed. If the filter is clogged with hair, dirt and other debris, the air will not properly be dispersed. This can cause the central air conditioner unit to overheat. Remove as much of the gunk as possible, and then soak the filter in soap and water to clean it. If it is too far gone, you can replace it with a new filter.

Step 2 – Internal Dirt

Since the main unit is positioned outside the home, it is prone to become dirty. Debris can get lodged inside the units, wrapped around the fan posts and other such hazards. If this happens, the air conditioner unit may not be able to properly spin the fan or exhaust air from its other parts. Turn the unit off at the circuit breaker, and then use a screwdriver to remove the fan cover. Inspect the inside of the case for debris and remove what you can. Use canned air to spray off caked on dirt and other debris that may be stuck.

Step 3 - Damaged Components

It is possible that the wiring can go bad. If you attempt to remove and replace many of the internal components, you will rack up a lot of costly parts and may never get to the bottom of the problem. The easiest way to determine if something inside is faulty is to use a voltage meter. Use the prongs to touch each wire lead. If there is current, you can move on. Remove any component that does not register, and replace it with one that is equal in quality.
