Craftsman 33 gal Air Compressor 6 hp Horizontal k Oil Free Pump Questions & Answers

Compressor starts innitially,then when pressure
the start capacitor on the motor body is weak,the motor needs this component to over come the air pressure when cycling to re-build the low air pressure,change both the start and run capacitors when doing the start because the other run capacitor is just as old and it will soon fail

The compressor runs fine and shuts off when the
Check the circuit feeding power to the compressor. These conductors may be too small. Conductors have a degree of resistance. Resistance consumes power. The power conductors consume is dissipated as heat and present a voltage drop to the equipment being served. Length and size of the conductors determine power loss.
An electric motor momentarily needs up to six times the running power and this power loss is squared ( PxP) at start up.
The bottom line: Shorten the length of the conductors or increase the conductor size to avoid voltage drop.

Leaking around Pressure Switch. Ordered & replaced switch but still leaking
Some pressure switches have a valve that reliefs the compressor head pressure when the motor stops and closes the head pressure relief valve when the motor runs.
There is a check valve that keeps air pressure from coming back to the compressor head and the relief valve.
I think the check valve is leaking tank pressure to the relief valve and compressor head.
The check valve is where the pressure switch mounts on to and it mounts threaded on to the compressor tank.
Try replacing the check valve

Line is fine, but still leaking
Take a spray bottle and put some soapy water in it; spray it on the path that air flows (line from pump to tank, pressure regulator, air line fitting) to find where the leak is. Once you find the leak will determine what has to be done to fix it.
**the soapy water spray will bubble wherever air is leaking**

Hi Ricky welcome to FixYa, I am Kelly
Do you know if your model number starts with 106, 919, or 921? Also is it an upright stationary or a horizontal portable compressor? I am pretty sure you have the Century 6 Hp motor. (Obsolete FYI) but I will try and find the correct capacitor. IF you do have the Century electric motor... it is going to be a long search.
Normally a Craftsman model number would be 106.xxxxyyyy or 919.yyyyxxxx that information would be very helpful.
