As we all know, air conditioning is essential in maintaining a comfortable indoor environment during the hot summer months. When your AC blower keeps turning off and on, it can be very frustrating and can also cause a significant dent in your wallet if left unchecked. Fortunately, there are several possible solutions to this issue. Here are some of them:
Fixing an AC Blower Which Keeps Turning Off & On: Solved


1. Check the Filter. Clogged or dirty filters can restrict airflow and cause your AC blower to turn off or on repeatedly. Make sure to clean or replace your filter regularly to prevent this from happening.

2. Check the Thermostat. The thermostat is responsible for regulating the temperature in your home, and if it's faulty, it can cause your AC blower to stop working. Verify if the thermostat is set to the correct temperature, and replace the batteries if needed.

3. Check the Circuit Breakers. The circuit breaker protects your AC's electrical system from overloading, tripping it when necessary. If your AC blower keeps shutting off, check the circuit breaker and see if it's tripped. If so, reset it and see if it solves the problem.

4. Check the Outdoor Unit. The outdoor unit houses several components that your AC requires to run correctly. If any of these components are damaged or malfunctioning, it can cause your AC blower to shut off or on frequently. Inspect the outdoor unit and look for any signs of damage or wear.

5. Check the Capacitor. The capacitor is responsible for starting and keeping your AC's motor running. If it's defective, it can cause your AC blower to turn off and on repeatedly. Have a professional inspect and replace the capacitor if needed.

6. Check the Fan Motor. The fan is responsible for circulating air throughout your home, and if the motor is defective, it can cause your AC blower to stop working. Inspect the fan motor and see if it needs to be repaired or replaced.

7. Check the Relay Switch. The relay switch controls the power supply to your AC's electrical components. If it's faulty, it can cause your AC blower to turn on and off repeatedly. Inspect the relay switch and have it replaced if needed.

8. Check the Compressor. The compressor is responsible for compressing the refrigerant and driving the cooling process in your AC. If it's damaged or malfunctioning, it can cause your AC blower to keep turning on and off. Inspect the compressor and have it repaired or replaced if needed.

9. Check the Ductwork. Damaged or leaky ductwork can cause air to escape, reducing your AC's efficiency and causing your blower to shut off or on frequently. Inspect your ductwork and have any leaks or damage repaired.

10. Contact a Professional. If you've tried all the solutions above and your AC blower still acts up, it's time to call for professional help. A licensed HVAC technician can identify the root cause of the problem and provide necessary repairs or replacements to get your AC running smoothly again.

In summary, a malfunctioning AC blower can be a significant inconvenience during the hot summer months. To prevent it from turning off and on repeatedly, make sure to follow the solutions provided above. Regular maintenance and inspections by professionals will ensure that your AC system continues to function efficiently and reliably.
