Troubleshooting Steps to Fix a Broken AC Unit Fan
Keeping cool when it’s hot outside requires a properly working AC unit. If your AC unit fan is not spinning, there are some ways to troubleshoot this common issue. The St Louis AC repair experts at Indoor Comfort Team regularly handle air conditioning issues, including the AC fan. We know what issues to troubleshoot and how to completely fix whatever is causing the problem.
One common issue that homeowners face is with a broken AC fan. Often the AC unit will appear to be running, but the fan is not spinning. And the air being blown out is not cool.
This can be a frustrating situation. There are several potential reasons for an AC fan to not spin, but some of them can be resolved without the need for professional help. Let’s explore some common causes and possible solutions for an AC fan not spinning.
Top 5 Reasons an AC Fan is Not Spinning
- Check the circuit breaker: The first thing you should do is check the circuit breaker associated with your AC unit. Sometimes, the breaker may trip due to overheating, causing the fan to stop spinning. If you find that the circuit breaker has been tripped, flip the switch back on. Some AC units have a shutoff switch on the unit itself, so make sure that it hasn’t been switched off accidentally.
- The problem may be with the capacitor, a small cylindrical component that stores energy and powers the air conditioner’s fans. If a capacitor becomes old or damaged, it can cause the fans to stop spinning. In this case, an HVAC professional will need to replace the defective capacitor. Ignoring this issue could lead to further damage, such as motor burnout.
- The fan motor is shot. The motor can burn out if it’s overworked or not properly maintained. If it is burned out, the motor will need to be replaced. Depending on the age of your AC, the whole unit may need to be replaced as motor replacement can be costly. A trusted HVAC professional will be able to let you know if it can be repaired or if it needs replacing.
- A clogged air filter can also cause the AC unit fan to stop spinning. Homeowners can easily tackle this solution themselves. Air filters can become clogged with dirt, dust, pet fur, pollen, and other debris, restricting airflow and causing ice buildup. If ice forms around the evaporator coil, the fan may stop working. If the evaporator coil is frozen, you should call a professional for assistance.
- Belt is damaged or broken. Older AC units rely on belts to drive the fan, and over time, these belts can become brittle and weak. If your AC unit has a belt-driven fan and the belt is worn, loose, or broken, it can cause the fan to stop spinning. An HVAC professional can easily replace the old belt, ensuring that the fan functions properly again.
Staying Cool All Summer Long
Summer is here, and the last thing you want is for your air conditioning unit to malfunction. A broken AC in the middle of a hot Missouri summer will leave you and your family sweating in the heat.
As you can see, when your AC unit fan is not spinning, it can be due to various reasons. From electrical issues, problems with the capacitor, a burnt-out motor, a broken fan belt, or a clogged air filter. Regular maintenance and timely repairs are crucial to help you keep your AC unit running well.
