SOURCE: When my compressor cuts out, it starts losing air

The air is probably coming through the unloader on the pressure switch. This is designed to vent the pressure between the compressor pump and the tank so that the compressor starts easier. This venting should only take a few seconds (5 to 10). If it bleeds air continuously, until the compressor restarts, then the tank check valve is bad. This is usually a fitting that extends into the tank. The small tube to the unloader usually goes directly from the pressure control switch to the tank check. Depressurize the tank, remove the check valve, and try to clean it. If that doesn't work, replace it.

Lefoo pressure valve leak


Where is it leaking from? If the unloader hisses for a few seconds when the compressor shuts off, it is working fine. If it hisses all the time when the compressor is stopped, it is still fine, but your in-tank check valve is toast. If it hisses when the compressor is running, you need a new switch.

I too am looking for a diagram. I am still trying just fit it back together and I have tried to get a diagram from Lefoo, no response to my repeated emails. If I do get it together I will post pics.

Releasing all pressure in the system can be achieved by removing the fuse to the suspension compressor and carefully loosening any airline in the system and letting the car bottom out, This will not fix anything. Without a good diagnostic computer check all the ride level sensors first, easy to check with a voltmeter for continuity.

When my compressor cuts out, it starts losing air by the auto pressure control (LEFOO LF10). I removed the plastic cover and felt the air coming out a little valve.

Porter cable compressor will not restart once it is under pressur


This is likely a bad check valve which is allowing pressure from the tank to leak thru back to the compressor. The compressor won't start because the compressor cylinder has air pressure on it.

The check valve is about the size and shape of a .410 shotgun shell -- it's in the copper line from the compressor to the tank.
