An AC Fan Not Working ? Well there are many causes of this problem. One of the main reasons is because of a bad capacitor. If you have a bad capacitor in your AC unit, then you need to replace it as soon as possible to prevent the fan from running continuously or at all. The other reason is if the speed of the rotation goes way too high. When this happens, then the motor will have to work double time to produce the same result.
If your central ac fan motor has a bad capacitor, then you should go to the internet and look for a capacitor. If you can’t find one there, then go to the local department store and talk to the person who sells air conditioners. They should be able to tell you what type of capacitor they have and where you can get one. You may also be able to find a capacitor online. Just make sure that the model numbers are the same as the ones on your unit.
Another possible reason that your AC unit is not functioning is if there is a contactor problem. If this is the case, then you will have to check the circuit breaker to see if it is the one that is causing the problem. If the breaker is the cause, then you will have to replace it. With a contactor issue, you will need to remove the air conditioning compressor from the system so that you can safely check the contactor. This will require unscrewing the vent hose off of the compressor.
Disconnect the power to the unit
Then you would need to disconnect the power to the unit. After that, you would have to take out the wiring from the AC to the thermostat. After that, you would have to locate the thermostat and remove it. Then you would have to remove the cover plate and then take out the wires. If you are unable to do this yourself, then you might need to get someone who knows about electricals to help you out. Make sure you read any instructions that come with your compressor before you start to do this.
You should then locate the two fans that are located in the back of the air conditioner. One of the fans should be attached to the AC condenser while the other should be connected to the B/S duct. You should notice that there is a yellow wire that goes between the two fans. This is the wire that connects the condensers to the air handler unit. Now you will have to use your screwdriver to remove the screws that are holding these two fans in place.
Locate the metal tabs
If the condenser is the problem, then you will need to locate the metal tabs that are located on top of the compressor. You should loosen them and then pull them towards you. This will allow you to reach the contactor unit and remove it. If your AC unit is the only one that is not working, then you can still hear a hissing or whirring noise even if there is a compressor that is not located near your home.
If the noise from your fan is not from the compressor, then it could be coming from the air conditioning unit itself. This could mean that the unit is not properly installed. Before calling an air conditioning contractor, you should try to locate the areas where the noisy fan is coming from. You should try to turn the air conditioning unit upside down and see if it works.
These are some basic things that you should know about fixing an ac fan. If you want to fix the unit yourself, you should be very careful not to damage the machine itself. For those that already have a damaged a fan, you should find a good replacement before calling an air conditioning repairman. You can find these products in your local hardware store. If they are too expensive for you, then you can always get an electrician to fix it for you.
