My I.R. 15 HP rotary screw will not load, any HELP?

Have a 2003 Ingersol 15 HP rotary screw. Will not load properly. Have replaced all three parts-( solenoid valve; blowdown valve and pressure switch) and no luck. All piping is correct and compressor pump is good.Loads to about 50 psi - 100 psi and stops loading or does not load at all. Any HELP?

Rocky, it looks to me as though you have replaced all the components that affect loading.

If you are sure that the pressure switch is wired right, and is the correct settings, then sorry, it's time to call in a pro compressor repair company.

Cheers,

Bill
