The heat of the summer is quickly approaching. Your air conditioning unit will soon be working overtime as a critical element of your cooling comfort. If your AC stops working during the summer, it could become dangerously hot very quickly, causing health concerns. Your air conditioner professionals in Bristol at Thompson Electrical Service are sharing what to do when your AC unit’s fan stops working.

The Unit’s Two Fans

Inside your central air conditioning unit, there are two fans. One is located inside that will blow cool air into your home or business. The second one is located outside, which blows air over condenser coils to release heat from your home or business’ air. When something goes wrong with either fan, your air conditioner will no longer be able to cool your home or business properly.

5 Reasons Your AC Unit’s Fan Stops Working

1. Capacitor Problems – The capacitor on your AC unit is designed to store the energy that powers both fans. Due to various causes, the capacitor on your unit could stop working and force one or maybe both fans to stop spinning. With your AC unit’s complex systems, it is recommended to call a professional electrician in Kingsport from Thompson Electrical Service to repair the problem.
2. Contactor Problems – An electrical switch that controls the condenser fan motor and compressor is the air conditioner contactor. Over time, it is normal for the switch to wear out, causing the outside fan to stop working. To avoid additional problems with your unit, it is best to have a trained AC technician in Johnson City from Thompson Electrical Service to remove the old switch and replace it with a new one.
3. Burned Out Motor – With so much use in the hot summer months, fan motors can go through excessive wear and tear. When faced with too much stress, the motor could easily burn out. If your air conditioning unit is not properly maintained, it could burn out, leaving you to sweat in the heat. Depending on the age and condition of your system, a bad fan motor could create a series of problems requiring professional AC technicians to repair or a full unit replacement.
4. Broken or Loose Belt – Older systems were built using belt-powered fans. The belts often slip, loosen, or break when used a lot during the warm summer months. Although the belts can still be replaced or repaired, it may be time to consider updating your air conditioning unit. Not only will you no longer have to worry about the problem with belts loosening or breaking, but a new unit could save you money as it would be more energy efficient.

5. Unit Not Receiving Power – Some units have a problem getting full power, creating an issue with the fan. While most air conditioners run well during the summer months, different parts could overheat during the middle of a heatwave and cause the circuit breaker to trip. A simple HVAC troubleshooting tip if you think the unit isn’t receiving power is to check the circuit breaker. If the circuit breaker caused the unit to power down, flip the circuit back on. However, if the unit continues to shut off repeatedly, it is time to call your AC technician.
