Running constant

[James]

My compressor continues to run and will not cut off. What could be wrong here?

Hi James,

If the compressor runs, builds pressure and then continues to run past the normal shutoff point then the problem is the pressure switch. The pressure switch is part #N003307.

If the compressor runs but doesn't build pressure or builds to a pressure lower than the pressure switch cutoff point and won't build anymore then the piston and cylinder are worn out. The piston & cylinder are sold as a kit which is part #KK-4964.

I hope this helps with your repair!
