Should your air conditioner suffer from a problem with its fan motor, there are a number of signs you can look for that will signal it is time to call an air conditioning professional to inspect and repair the problem. Here are three such problems and what you should do about them.
Fan Shuts Off
If your fan turns off before the cycle is fully completed, there may be an electrical issue that keeps it from continuing. Bad wiring, a short out in the motor itself or an issue with the circuit breaker or fuse may cause this problem, and it should be inspected by a professional right away. In many cases a single part can be replaced to repair the problem.
No Air Flow
If your fan is on but is not actually circulating air, either because it is not only high enough or because of another issue, it can be due to a couple possible problems. It may be worn to the point that the fan itself needs to be replaced or it may be that the motor is dying – a natural problem late in its life cycle. Other possible issues include loose screws or wiring or an actual obstruction in the fan assembly.
If the fan motor is making a lot of noise, most likely it is because of a loose part clanging against the body of the fan motor when it is running. If this is the case, you can look for such a loose part, though because this repair often requires opening the cover to the fan motor, it is recommended that you call a professional for any such inspections.
Whatever your issues, it is important that you call a Phoenix air conditioning professional to repair the problem. Fan motor problems are often electrical and it can be dangerous to work on them without specific expertise working on electrical systems.
