AC Fan Not Working? Troubleshoot the Problem
When an air conditioner’s fan is not working, it can be an easily overlooked problem that can quickly escalate into larger, more damaging, and expensive repairs. Unfortunately, the fan motor on an air conditioning system is a common source of issues and the root cause to many problems can be hard to pinpoint. But with a few basic troubleshooting tips, AC owners can identify and solve the issue with their fan.
Check Your AC Unit’s Power Supply
The most basic of all AC fan problems starts with a lack of power. While this may sound obvious, it can be easy to overlook common issues that can block the power’s flow to an AC’s fan motor. In residential AC units, power is usually supplied through the circuit breaker, while in commercial AC units, it is usually supplied through an outdoor disconnect switch.
The AC’s power source should be checked first, starting with the fuse box or circuit breaker panel. Make sure that the circuit is not only turned on, but that it is strong enough for the AC fan motor to maintain a consistent current supply. If any of the fuses have blown, replace them as necessary and reset the circuit breaker.
Examine the Compressor and Capacitor
Assuming that the power supply is working properly, it’s time to look a bit deeper into the AC unit’s components. Sometimes, the fan motor will not start because the compressor is not working. To check this, turn the AC off and turn the fan setting to “On”. The fan should continue to run even when the compressor is off.
If the fan fails to run when the compressor is off, then the issue could be with the compressor or the capacitor. First, disconnect the capacitor’s power supply and test it with a multimeter. If it has failed, then a replacement capacitor will be necessary. If the readings indicate good capacitance, then it is likely the compressor is the issue and a professional appliance repair technician would need to diagnose the issue further.
Check Connections and Lubricate the Fan Motor
If the air conditioner fan motor itself is the root cause of the issue, then a faulty electrical connection could be at the source of the problem. In the case of smaller, oscillating fans, the connection between the motor and the fan blades may have come loose. In this case, the fan simply needs to be reconnected to get it spinning again.
For larger low-level fan motors, the motor may be frozen due to improper lubrication. This is a common problem for newer air conditioners, as the fan motor can run dry for years without any maintenance and eventually cause the fan to corode and lock up. If this is the issue, the fan motor will need to be oiled and lubricated to get it running again.
Call a Repair Technician
If the AC fan motor simply refuses to start, then it could be the result of a blown or damaged motor. In this case, a professional repair technician will be needed to inspect the motor and possibly replace it. A repair technician can also properly test the motor and other electrical components in the AC unit to determine if a new motor is required for the repair.
Ultimately, the best way to handle AC fan problems is to seek help from a professional and reliable appliance repair technician. These technicians are experts in AC systems and can diagnose and repair any issues quickly and cost effectively, resulting in increased peace of mind and significantly less money spent on AC repairs.
