Resusitating My Campbell Hausfeld Compressor

[Peter S]

I have a 5 HP Campbell Hausfeld compressor that just quit suddenly. I thought the plug was about to pull out of the socket, pushed it back in, and the compressor refused to start again. I may have momentarily broken contact, but I can't see why that would cause a total ongoing shutdown.

Anyhow, the manual is no help. Does anyone have any ideas on trouble-shooting a unit like this one?

Its a WL66000 series from about 2005.

Peter s,

Does the motor have a resettable overload? Did you check the supply circuit breaker/fuse?

Check power supply mode is it normal ? ? .. Use stabilizer for check the power amps which On to Off the machine.

What do you mean by plug pull out of socket? Out of the wall socket? I'd pull the cover to the pressure switch (unit unplugged of course) and just check all the connections. Make sure you don't have any stray strands and connections are tight. Clean the pressure switch. Then cover it up, plug in, hit the thermal reset (if applicable) on the motor and turn on the main switch. If this doesn't work you will need to check voltages coming out of the pressure switch. You might have a start cap or winding issue, so don't leave it powered on if it doesn't begin to spin up and the tank pressure is in the run range.

I'll give this a shot.

Yes, the plug started to fall out of the wall socket because I tugged the compressor a bit too hard.

Egg all over my face.

Turns out that there is a blown internal fuse inside the cover. I don't think this shows on the schematic. I think I blew it by shoving the plug into the socket after it broke contact momentarily. Hopefully it didn't blow for some other reason.

I am going to print out this advice, as the life of these cheap compressors tends to be nasty, brutal, and short without a lot of tinkering.

Hope this is it, and thanks so much.
