Common Electrical Problems with Air Conditioner Units

Electrical problems can put a strain on your air conditioner or prevent it from working altogether. AC units are full of electrical components and several things can be the cause of your trouble, but there are a few common electrical problems that your unit may experience.

Fans

The blower fans have the job of blowing the cold air through the vents into your home and pulling warm air out. There is wiring that is run around that connects the blower motor and the fans. If these wires become faulty, the fan it powers will stop working properly. Air flow becomes reduced, putting a strain on the other fans.

Capacitors

Capacitors are the small cylinder shaped pieces that have the job of carrying electricity to the blower motors. Each separate motor has two capacitors. One starts the motors while the other keeps the motors running. A clicking sound can be a sign that a capacitor is not functioning properly.

Compressor

In an air conditioner unit, the compressor is responsible for compressing the coolant in the coils that cools the air as it flows through. For the compressor to do its job, it must have a consistent voltage flow. If the voltage is too weak or too strong, the compressor can stop working. Compressors that turn off too soon are usually not getting enough electrical current. On the other hand, if the compressor has stopped working, it could be due to too much current. It can be replaced, but the unit should also be checked for the electrical problem and be repaired as well.

Relays

Air conditioners have relays that have the job of controlling the high-voltage parts and bringing power to them. Electrical relays are an important part of the unit’s operation. If the motor does not turn on, a relay could be stuck in the open position. When a unit does not turn off, a relay could be stuck in the closed position.

Electrical repair for air conditioner units can be complex and dangerous for inexperienced people. You should not attempt to make repairs on your own. The risk of accidental electrocution or potential damage to the home is too high. If you are experiencing cooling troubles, or you think there may be a problem, a qualified professional should handle the inspection and repair.
