AC Fan Not Working? Try These Safe Checks
Before scheduling a repair, homeowners can perform a few basic checks. Do not remove electrical panels or handle live wiring.1. Check the Thermostat
Set the thermostat to COOL and lower the temperature several degrees below the current indoor temperature. Make sure the thermostat has power and the fan setting is appropriate.2. Inspect the Air Filter
A severely clogged filter can restrict airflow and contribute to coil freezing or system problems. Replace a dirty disposable filter with the correct size.3. Check the Circuit Breaker
Look at the electrical panel for a tripped breaker associated with the air conditioner. If it has tripped once, resetting it may restore power. However, if it trips again, stop resetting it and call4. Look at the Outdoor Unit
If the indoor blower works but the outdoor fan does not, the problem may involve the capacitor, fan motor, contactor, or electrical supply.Outdoor AC Fan Running Problems
The outdoor AC fan plays a critical role in releasing heat from your home. When it stops spinning, the condenser can become excessively hot and the compressor may be placed under significant stress.A bad capacitor is a common cause of an outdoor fan that will not start. Other symptoms can include buzzing, humming, intermittent operation, or a fan that starts slowly and stops.
Never attempt to push-start the fan or work inside the condenser cabinet. A technician can test the capacitor, motor, voltage, and electrical components using appropriate equipment. If you need AC fan repair in Boise,
Indoor AC Fan Not Working
Sometimes homeowners say the AC fan is not working when the actual problem is the indoor blower fan. If little or no air comes from the vents, possible causes include a faulty blower motor, dirty filter, frozen coil, thermostat issue, or control problem.A useful distinction is whether the outdoor unit and indoor blower are both operating.
Outdoor unit running + no indoor airflow: The indoor blower system may need attention.
Indoor airflow + outdoor fan not running: The outdoor condenser fan may be the problem.
Neither unit running: Check thermostat settings and power, then seek professional diagnosis if the system remains inactive. Call
