My central air run capacitor went out it was 440 volts 20 microfarads can i use a capacitor with 450v 16mf?
anyways bottom line will a 450volt 16 micro farad work
it takes a 440 volt 20 micro farad capacitor
its hot and i want to know if this will work till tommarrow

it will be alright until you can buy the correct one....the voltage is fine but since the microfarads are lower the unit will pull more amps...it will also have a harder time starting even if you cant notice the difference..the general rule of thumb is you can go plus or minus 10 percent of the original one and be safe...since yours is more than 10 percent then you need to get the correct one as soon as possible..

The ratings are so close that it will probably work quite well, actually. You may want to just leave it in place until it quits, then replace it with the exact match - which of course you will buy in the next day or two, right? But don't replace the 450v capacitor until it quits, unless your aircon supplier says that it's a must. Ask him.

the objective of the capacitor is to alter the portion of the ac so the motor will start up. the voltage isn't a controversy the capacitance is 20% off. which may be in the tolerance of the cap. of direction if the recent one is 20% low now u have approximately 13MF which makes concerns worse. it is going to probable artwork, yet i think of i might replace it ASAP with the main recommendations-blowing capacitance. The decrease capacitance could reason it to overload, extraordinarily if it tries to restart at as quickly as after a end. (height load)

The voltage is fine so long as it's the same or higher, which it is. The 16 Mfd will probably be alright also. However a 20 will be more efficient and should be installed as soon as you can get one.

It would probably work, but an exact match would be preferable.
