How to install a/c capacitor

May 26, 2008

- The capcitor is a cylindical shaped device that fires up the start circuit pof your A/C. have you got the covers off yet. FIRST be sure to disconnect fully from the power supply. If you do not have a circuit breaker next to the unit, then you will need to isolate it from the mains powwer supply. You will need to remove it from the window.

- Air Conditioner Capacitors
There are two critical specifications that need to be identified when looking to replace an air conditioner's fan or compressor run capacitor, the voltage and the capacitance rating in microfarad (uF or MFD). The physical size and shape (round/cylindrical or oval) is irrelevant except for mounting considerations and you will often find newer capacitors considerably smaller then old ones of the same rating.
As a replacement you can use an alternative of a higher voltage rating without any problems but the capacitance should be within 10 percent of the original but an exact replacement is always best.
Some models may utilize a 'dual' capacitor where the compressor and fan motor capacitor are built into one. On this type you will see 3 groups of terminals across the top of it. There will be one set of common terminals, one group for the fan motor and another for the compressor wiring.
The common terminals on a dual capacitor will usually be indicated with the letter "C" near the associated terminal set, the fan side may or may not be indicated. The compressor will almost always be indicated with the word "herm" (short for hermetic) indicating part of a hermetically seal system (which the compressor is part of).
Dual capacitors are usually considerably more expensive to replace than single purpose ones.

- I searched for a service manual for you to make the job easy, but did not find much of anything unfortunatly. I was able to locate a source for the part you need. :)

You can purchase the part you need online from here

The part is not hard to change, as it mounts with a clamp, and has some wires connected to it. They just need to be replaced to the new part as removed from the old one. If you need more advice, or just a confidence boost.. :)
I am here to help, just let me know.

Thanks for using FixYa
