Central Pneumatic 95630 Compressor Won't Start

I used the compressor a few times today, and then when I went to use it again later, it just won't do anything when I flip the switch. I tried using different outlets, made sure the switch was still good, checked to make sure the cap was still good. All seemed fine to me. No residual pressure, there's no tank and I made sure there was no pressure built up in the hose. Don't know what else to check.

And, if for any reason, the PRV didn't let go at over pressure, you would have a very dangerous situation.

It were my compressor I would not run it until I had a functioning pressure switch.

Well, you can, but you run the risk of it going overpressure and blowing the PRV, thus losing a lot of air, and also probably wearing the piston faster than normal.

If you've found a part to substitute, that's fine - if not consider getting a different switch altogether and using a nipple to connect it.

Good luck.

Shorting Worked
by: Dominick

Not sure if my previous comment got posted, but the compressor worked by bypassing the pressure switch. I tried to look for a number on the switch, but I didn't see anything, maybe it's under the rubber coating. Couldn't seem to get the rubber coating off, but I guess I can get a little destructive now that I know it isn't working. Can I use the compressor bypassing the pressure switch by just turning the compressor off when it gets to high of a pressure? I'm sure its not very safe, but it would be nice to be able to use the compressor while I wait for a new part.

What's left is the pressure switch, 31 on the drawing.

Just for testing, you can try shorting the terminals of that, and turn it on - briefly - just to see if the motor runs. I'm betting it will.

If that's the problem, you'll probably have to find a part number on the switch itself and get a replacement from someone other than HFT.

Let us know how you get on with it, please.
