Best Answer

A capacitor in an air conditioner stores and releases electrical energy to help start the compressor and fan motors. It provides the initial surge of electricity needed to get these motors running and helps maintain a steady flow of power during operation. If a capacitor fails, the motor may not start or run efficiently.

Where can you buy a capacitor for air conditioner unit?

Air conditioner capacitors may be purchased from appliance-parts retailers. There are many with web sites.


Can a larger capacitor be used in an air conditioner?

Function of Capacitor in Air Conditioner:Compressor Motor Capacitor: This air conditioning capacitor usually consists of two capacitors that are combined. This vital capacitor gets the motor running in the air conditioning unit.Start Capacitor: This capacitor provides auxiliary support and that is not a standard on every air conditioning unit. It can give the motor a boost to get it started.Indoor Blower Motor Capacitor: This capacitor is self-explanatory. It is responsible for starting the indoor-blower-motor and keeping it running efficiently.Outdoor Fan Motor Capacitor: The name says it all for this capacitor. It starts the outdoor fan and keeps the air flowing through the coils that run on the outside of an air conditioner.


Does air conditioner capacitor size affect cooling?

Yes, the size of the air conditioner capacitor can affect the cooling efficiency of the unit. A properly sized capacitor allows the compressor and fan motors to operate at optimal levels, ensuring efficient cooling performance. If the capacitor is undersized, it can lead to reduced cooling capacity and increased energy consumption.

How do you differentiate a start capacitor from a run capacitor in air conditioner?

If the air conditioner has both, the run capacitor is likely the largest one. The start capacitor will only be in the circuit for a very short time, so overheating doesn't become an issue. The run capacitor must be sized for continual use.


What is an air conditioner capacitor measured by?

There are two measures used to describe the cooling capacity of an air conditioner. One is BTU or 'British Thermal Unit' but that is the old way of doing it. The modern way is the Kw or Kilowatt of cooling. to get BTU you have to multiply Kw by 3412. A small air conditioner for maybe one person in a little office might be 9000 BTU or 2.6 kW, a large industrial air conditioner for a bigger area might be 35,000 BTU or 10.26 kW.


How does a central air conditioner compressor act when the capacitor burns out?
