Husky H1820F not shutting off at pressure set

My Husky H1820F compressor doesn"t shut off, have to manually shut it off with the push pull switch,how do I get it to stop when it reaches required pressure? Thanks in advance for your responce. Dave

Dave, if your air compressor runs and the compressor tank pressure builds to the point where the PRV lets go, the first suspect is a failed pressure switch.

If your compressor runs but the pressure never gets to the cut out pressure level, that's another series of issues.

Which is it for your air compressor?

Cheers,

Bill

Same Problem here . it built pressure but does not cutoff by it self. I press red stop button.
It works well for 2 year. used for just fill air in tyres at gas station.

Please let me know how to repair it.

If an air compressor runs and builds air pressure, and the pressure in the tank builds past the normal cut off point, ultimately the pressure relief valve will blow off to prevent over-pressurization.

The PRV is the second line of defense.

The first line of defense is the pressure switch. When the tank pressure reaches the cut out pressure setting, the diaphragm in the pressure switch has enough force to trip the pressure switch to off. If that is not happening, that is a pretty good indicator that the pressure switch is pooched.

Hi there. Are you saying that the compressor runs up to 125 PSI tank pressure, and before the compressor shuts off, the PRV lets go at 125 PSI?

What is the normal cut out pressure of your air compressor before you changed the gauges?

And, which gauges did you change, please?

Cheers,

Bill
