In a perfect world, your home's air conditioner would run all summer long, year after year, without any problems. Unfortunately, most air conditioners will experience issues at some point, and they will need to be repaired by an experienced HVAC professional. It can be very alarming to discover that your air conditioner is not operating properly on a hot summer afternoon, but rest assured that most air conditioning problems can be repaired. One common issue that can cause a problem with a residential air conditioning unit is a bad A/C fan motor. The A/C fan is responsible for circulating cold air, so if the motor is bad you will notice problems. Some signs that you need to have your air conditioning unit's fan motor replaced include the following.
Fan Does Not Turn On
When you set your home's thermostat and switch on the air conditioner, your air conditioning system should start up automatically when the temperature inside your home exceeds the temperature on your thermostat. If you are positive that you have set your thermostat properly and that you have set it to the air conditioning mode but the fan never turned on, it is likely due to a bad A/C fan motor. Your A/C fan will not be able to start up and do its job if the motor is bad.
Odd Sounds From Outdoor Condenser Unit
If you own a home, it is a good idea to go outside and observe your air conditioner's condenser unit while the air conditioner is running. If you happen to notice any buzzing, rattling, or strange humming sounds, that could indicate that there is something wrong with the A/C fan motor. Anytime that you discover that your air conditioner's condenser unit is making strange noises, it is best to contact an HVAC repair company to check it out so the issue can be repaired before your air conditioner stops working altogether.
Air Conditioner Turns On and Off Intermittently
When you're running your air conditioner during the summer months, pay attention to how often it cycles on and off and how long it runs. In the event that your air conditioner starts turning on and off intermittently, there is usually a problem. Usually, this means that the fan motor is overheating, which signals the air conditioner to turn off. When the fan motor cools down, the air conditioner begins running again. Eventually, the air conditioner will stop running altogether if the fan motor fails. It is in your best interest to have the A/C fan motor replaced before this happens.
