Fans malfunctioning amongst air conditioners is a common problem. Sometimes, it is simply an age problem whereas in other cases it might be due to much complicated reasons, for which you need the expertise of AC repair services. This blog shares a list of troubleshooting tips if you observe the AC fan not working and don’t know how to fix it.
The Fan Does Not Spin And You Can’t Hear The Compressor
Most people assume that the compressor turns on when the fan is spinning. That is not the case. Even if the fan is not working, you can still hear the clicking or humming sound of the compressor. It does not rely on the fan to operate. So, when turn on your HVAC, go to the compressor and inspect if you’re hearing anything. If neither the fan is working nor the compressor, the fan is not the culprit. It might be that the compressor is not receiving the appropriate voltage to function.
To solve this issue, you should first turn off the AC and take a look at the circuit breaker. You will find a switch termed “HVAC” or “Compressor” etc. You should switch it on and then try turning the air conditioner on again. However, if the switch is already on, turn it off for a few seconds and then switch it back on while turning the AC unit.
The Compressor Works But The Fan Doesn’t Spin
If you observe that the compressor is working but the fan is not working, it might be due to a faulty capacitor. It is the capacitor that turns on the fan. A fan while it is running does not require much energy but when it comes to starting it, it needs a jolt of power. The capacitor is designed to store electricity so that it can utilize it to start the fan.
To diagnose the capacitor problem, you need a long piece of wood or a non-conductive material to kickstart the fan. The AC should be turned on and then try using the stick hard enough to spin the fan. If the fan works, you need to replace the capacitor. However, if the fan still doesn’t work, the problem is somewhere else.
It also might be that the fan does not spin due to a bad motor. This problem is common amongst units that are not properly maintained. The accumulation of dirt and debris over time can kill its performance. If your unit hasn’t been maintained well, you should consider replacing the bad motor.
The Fan Spins Slowly
The next problem relates to the fan spinning slowly. You might encounter this problem when the unit is running or when you attempt to kickstart the fan. This has an easy solution. You should check the air filters. Many times, if the air filters are not cleaned, they become clogged and don’t let the fan spin normally. Due to this, the fan runs slowly or doesn’t work. Improve the performance of your AC by keeping the air filters clean.
The Fan Spins Slowly And Loudly
In some cases, you might hear the fan making grinding noises while spinning slowly. This is usually due to the accumulation of dirt and debris, preventing the fan from operating normally. Troubleshooting the problem requires turning the AC off along with the circuit breaker. Then, check the components if they are grinding against debris or anything else. If the case is otherwise, turn the AC on and try to determine what is causing the noise.
The Fan Turns On And Off Randomly
If you observe that the fan is turning On and Off randomly at random times, it must be a problem with the wiring, control board, or any other electrical component that controls the fan. To solve this issue, you will need to call a professional who can check the whole unit and diagnose the actual problem.
Concluding, we hope to have shared everything you need to know about troubleshooting AC fan problems. Meanwhile, you should ensure that your air conditioner is maintained to keep it free from dust and dirt. However, if the problem seems more complicated, you shouldn’t try to fix it yourself anymore and check with an air conditioner repair service Fairfax for inspection and repair.
