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.

It can provided all of the specifications are the same. Generally start capacitors have different capacitance values than do run capacitors.

Central air conditioner not blowing air?

Depending on the make and model of the air conditioner. It is probably your blower motor. There are two, possibly three items to consider. The motor, the start capacitor and the run capacitor. Some systems will have just the motor and the start capacitor. Some have just the motor and the run capacitor. Usually (not always) the capacitor will show physical signs of failure. Burned terminals, swelling or white stuff coming out of the top. Expect to pay $30 for the capacitors and several hundred for a new blower motor.

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.
