Ac fan motor maintenance. 1866 products in air conditioner capacitors. An ac capacitor also called a run capacitor is a small cylindrical object that sends energy to the motor that powers an air conditioning system. 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.

When the air conditioner needs to come on the capacitor sends a high voltage jolt upwards of 400 to 600 volts to the compressor fan motor and blower motor. The reading should be within 10 percent of the rated capacitance on the capacitor. It is connected to the condensing unit power supply 220v and collects energy until it is needed. 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.

If the reading doesn t match the rating replace the capacitor. 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. In short it s like a rechargeable battery. 370 volt 50 5 mfd round double run capacitor.

While the run capacitor stays on giving the motor extra torque when needed. 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. While your air conditioner is running the capacitor collects and stores energy. Air conditioners fans air conditioner capacitors.

Once it is discharged use a capacitor tester to check the microfarad reading. Often a bad capacitor will need to be replaced by a professional. A capacitor stores up energy that provides power to your air conditioner s fans. 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.

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. How ac capacitors work a capacitor is a piece of electrical equipment that stores energy. A capacitor is a small cylindrical device inside your air conditioning unit that supplies and stores electrical energy. The start capacitor gives a fan motor the torque it needs to start spinning then stops.
