Symptoms of a Broken AC Motor

Symptoms of a Broken AC Motor

During the hot summer months, you depend on your central air conditioner to keep you and your family cool. However, if the motor goes bad, your air conditioning unit will not be able to do its job properly. If you have noticed that your home stays warm, look for the following signs that the AC motor is broken.

  • Loud Noises Are Present While the Compressor Is Running
    One of the first and most noticeable signs that an AC motor is broken is the presence of loud noises whenever the compressor is running. At first, you may hear a low humming or buzzing sound. However, as the motor continues to fail, the noises will become louder, and you may also hear a rattling noise.
  • Exterior Fan Blades Are Slow or Not Moving at All
    You can discern another sign of a broken AC motor by observing the exterior fan blades that are located on top of the unit. Normally, when the compressor is running, the fan on top of the unit will spin rapidly.

    If the motor is failing, however, the blades will start to slow down to the point that you can see the blades as they rotate. Eventually, if the motor is not repaired, you will find that the blades do not turn at all.

  • Unit Rapidly Cuts on and Off
    While observing the cycles of your unit, you may find that the compressor rapidly cuts on and off. When this rapid cycling occurs, the air conditioner is likely overheating and is shutting itself off as a safety precaution. If the motor continues to overheat, and the rapid cycling keeps occurring, you may end up with a motor or compressor that burns up and fails.
