Central Air Conditioning Fan Capacitor

Air conditioners fans air conditioner capacitors.

Central air conditioning fan capacitor.

It is connected to the condensing unit power supply 220v and collects energy until it is needed. 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. Often a bad capacitor will need to be replaced by a professional. 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.

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. While the run capacitor stays on giving the motor extra torque when needed. 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.

A capacitor is a small cylindrical device inside your air conditioning unit that supplies and stores electrical energy. 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. 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.

A capacitor stores up energy that provides power to your air conditioner s fans. How ac capacitors work a capacitor is a piece of electrical equipment that stores energy. Brown to fan red to c purple to c yellow to herm each brand of system may vary. In short it s like a rechargeable battery.

The fan motor is one of the most important components of your air conditioning system. For pricing and availability. 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. 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.

Ac fan motor maintenance. Once it is discharged use a capacitor tester to check the microfarad reading. The reading should be within 10 percent of the rated capacitance on the capacitor. The start capacitor gives a fan motor the torque it needs to start spinning then stops.

If the reading doesn t match the rating replace the capacitor. While your air conditioner is running the capacitor collects and stores energy. 370 volt 50 5 mfd round double run capacitor. 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.
