Central Air Conditioning Fan Capacitor

The reading should be within 10 percent of the rated capacitance on the capacitor.

Central air conditioning fan capacitor.

Often a bad capacitor will need to be replaced by a professional. While the run capacitor stays on giving the motor extra torque when needed. The start capacitor gives a fan motor the torque it needs to start spinning then stops. Find my store.

When your air conditioner is powered on the capacitor s job is to provide a high voltage jolt around 400 to 600 volts to the compressor fan motor and blower motor. The ac capacitor gives your ac system the initial boost it needs to turn on and also provides continuous power for it to keep running. Take the screwdriver and touch both the fan and the c common tabs on the top of the capacitor to discharge the fan side of the capacitor. Ac fan motor maintenance.

Capacitors serve different functions in different electrical appliances and devices but in a central air conditioner the capacitor serves as a kind of battery that stores the electrical current at a level sufficient to start the various motors in the system the compressor the blower motor and the outside fan. A start or run capacitor can be combined into one capacitor called a dual capacitor with three leads but can be split between two separate capacitors. In short it s like a rechargeable battery. The fan motor is one of the most important components of your air conditioning system.

How to test your air conditioner capacitor. The air conditioner s compressor blower motor and fan motor all rely on the compressor or compressors depending on your air conditioner to keep running and cold air running through your home.

If the reading doesn t match the rating replace the capacitor. Make a note which wire is connected to which terminal ex. A capacitor is a small cylindrical device inside your air conditioning unit that supplies and stores electrical energy. Air conditioners fans air conditioner capacitors.

However your capacitor can go bad for various reasons and stop working properly which will force one of your system s fans to stop spinning. 370 volt 50 5 mfd round double run capacitor. Once it is discharged use a capacitor tester to check the microfarad reading. 1866 products in air conditioner capacitors.

Brown to fan red to c purple to c yellow to herm each brand of system may vary. That way when it s time for that big burst of energy your air conditioner needs the capacitor can supply it and keep things running smoothly. While your air conditioner is running the capacitor collects and stores energy. How ac capacitors work a capacitor is a piece of electrical equipment that stores energy.
