Troubleshooting Common Problems with Your Air Conditioner Fan Motor Troubleshooting Common Problems with Your Air Conditioner Fan Motor
Air conditioner fan motor problems that are common include a fan motor that runs too loudly, the fan is not circulating air or the fan shuts off during operation. These common problems can occur at any time when the air conditioner is operating and are signs that either the air conditioner is too old and needs replacement or that some part inside the air conditioner needs to be replaced.
The best way to troubleshoot and fix problems with your air conditioner is to recognize the existence of the problem and determine where it is coming from in order to have it addressed. Simpler problems can be fixed by you as a do-it-yourself project, but the more complicated issues that you encounter are best left to a qualified repair technician.
Air Conditioner Fan Motor Is Too Loud
In the case of the fan motor running too loud, this can be a sign that the air conditioner fan has something loose that is obstructing the motor and causing it to make noise. When you notice that the fan is running louder than it should, you need to listen to the sound of the running fan in order to determine what may be obstructing the air flow or causing the fan to work improperly. Open the cover to the air conditioner in order to get a better view of what is going on and make any necessary repair to restore the air conditioner's operation.
Air Conditioner Fan Is Not Circulating Air
Depending on the age of your air conditioner, it can be possible that the air conditioner fan motor is no longer able to work adequately to operate the fan and circulate air. You will notice that it seems that the fan works harder to circulate air in the room, but that the room is not getting colder. In this instance you will need to consider replacing the air conditioner fan with a newer fan in order to increase the efficiency of your air conditioning unit and restore its proper function.
Also look for any obstruction or loose part within the air conditioner fan motor to see if that may be the source of the problem with the fan not circulating air.
Air Conditioner Fan Motor Shuts off
If the air conditioner fan motor simply shuts off during the beginning or middle of operation, you need to replace the fan motor immediately. The motor has some type of electrical short or other problem that is causing it to fail during operation. This will only get worse over time. You may attempt a repair of the fan motor to identify and fix the short, but the time and effort that you spend in this type of an approach may be better spent finding a replacement motor and installing it yourself.
