Husky/CH Compressor check valve question
 
My 18 gallon Husky Compressor will build about 50PSI and then shut off. I have to unplug it of wait until the air pressure is all gone before it will repeat this cycle- never above 50PSI.

I have read a million stories from as many customers. I'd like to fins a definitive fix.

The lock tab on the unloader is worn away. The new unloader valve is$15. OK
The check valve is $25; but I don't know if it is the problem. What is the 1/8" filter type plug that screws into the Check Valve- opposite the 1/8" Black plastic tube to the unloader Valve? It leaks.

Post a picture, Huskey makes about a dozen differant set ups.
If the check valve is stuck air will be leaking back out of the pressure regulator.
Check for air leaks around the line that runs from the tank to the pressure regulatior. Also the line that comes out of the head of the compressor.
All there counting on to seal that line is a little round O ring and they fail. Copper lines work harden and crack, old rubber line from weather cracking. All of these can stop it from building up pressure.

With or without an extension cord?

Voltage drop would be an issue, I had the same problem with an Husky, I replaced the run capacitor, same issue, plugged directly to a 20 amp outlet no problem.

Yes, exactly Kirk. An compressor works harder and everything gets hotter as the pressure builds, and it is not uncommon for it to simply run out of juice at some point, if not supplied with adequate power.

If it was a leak though would it not keep running instead of not starting when low or shutting off too soon. Just a guess but if the regulator was bad would pressure on and off switch be effected.

yah.. thats something that drives me insane on small jobs for people when i have to run air... gotta walk around hte house with my 70lb compressor trying to find an outlet thats on a 20 amp circuit
