Hi

I have an old air compressor that needs new capacitors. One start and one motor run. I’m having trouble getting new replacements with the same values. Is it possible to use a higher voltage rated capacitor? Or do they have to be exactly the same?

Cheers guys

Higher voltage is never a problem. Lower voltage, or different capacitance can be.

Thanks for responding. The motor run capacitor (white one) has to values for volts. DC and AC. Does that have to be similar?

Voltage on a capacitor tells you how much it can deal with. The engineers who selected that capacitor chose a particular voltage. While is is possible that sometimes it reflects excess caution or parts availability, it is not a good idea to choose a lower voltage rating than you find in the absence of other information.

Stick to those values or greater to be safe.
