## Description

A capacitor is an electric component that temporarily stores an electrical charge. A dual "run capacitor" supports two electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled "C", "FAN", and "HERM", which stand for the *C*ommon, Fan, and *HERM*etically sealed compressor. Dual capacitors come in a variety of sizes, depending on the capacitance (µF or MFD), such as 40 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out. Same as an electric wire- 600V rated wire is better than 300V one .The capacitance(µF or MFD) must be the same or stay within +10% or -10% of its original value . Example: 50 µF cap can be substituted by 45 to 55 µF with the same or better voltage ratings capacitor . Round cylinder-shaped dual run capacitors are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor. You will ask “Why I need a Cap that is rated 440V in my A/C?” Answer: You need to realize that a motor is an inductive device. When the supply voltage is applied to the motor run winding, the voltage across the start winding will be increased to a higher voltage value. A motor acts like a transformer with the run winding acting as the primary and the start winding acting as the secondary. This is why the capacitor has a much higher voltage rating than the 230 being the supply voltage. If a Capacitor is not EIA-456-A approved means it is not approved for US market.

My central air conditioning fan was not spinning when turned on.  I researched YouTube and came across a few different causes for the issue.  Upon opening up the unit (AFTER CUTTING OFF POWER AT THE CIRCUIT BREAKER BOX) and visually inspecting the inside I noticed the capacitor looking expanded and a red power wire burnt to a crisp.  I checked Amazon and came across the exact capacitor type my unit had.  I can't believe how fast the item was shipped to me and how fast I was able to install it on my own.  Very easy process following a YouTube video.  I spent $14 for this capacitor which took me only 15-20 minutes to do the job.  As for the power wire, I simply cut off the burnt part of the red power wire, spliced to expose some copper and screwed the copper under a screw where it was originally located.  I took pictures before doing anything to know where each wire was located on the capacitor.I saved a lot of cash not having to call in a professional.  It's going on 2 weeks with no issues.  Highly recommend buying this capacitor if it matches your old one.  I could be wrong but my AC actually feels colder after the replacement.  Since the old one looked as if was about to burst I believe it wasn't working to its full potential.  Thank you!
