Compressor was turned on...charged up to 130 psi. I used the compressor, but when it was supposed to compress more air, it did not. Now, the on/off button does not turn the compressor on. I have verified power source. No reset button can be found. And I cannot locate the owner's manual.

The Square D pressure switch is set from the factory to turn off at about 130 psi. Look on the inside of the switch cover for details. If the contacts are welded together or other part failed in the switch the compressor will continue to run till safety valve opens. Replace the switch or just keep using the pilot valve. Good luck on repair.

First thing... that model of air compressor was recalled in 2011.

If that is of no concern to you... then look in the manual about how to adjust the cut-in pressure. The cut-in pressure is what controls when the compressor portion turns back on. There is often a set screw that controls this.

BE CAREFUL! Jump the pressure switch and see if it starts. If so, replace the switch. If it doesn't start but hums, cut the power and try to turn the compressor by hand. Free it up if possible. If it does not hum, look for a reset on the motor or a blown fuse or breaker.

Mike:

If you have air blowing out of the oil filler cap, I would suspect that the piston rings are shot. The piston rings are supposed to keep the compressed air above the piston, and air seems to be leaking past the piston rings into the crank case.

A regulator controls the pressure in the air line leaving the compressor and does not affect when the compressor turns on or off.

The pressure switch monitors the pressure in the tank and turns the compressor motor on and off when the switch closes or opens in response to changes in the tank pressure. If the compressor does not shut off, it is possible the pressure switch has been set to a pressure level that is higher than the compressor is capable of attaining, thus it does not shut off.

The compressor is capable of developing 150 psi and is noted as having a "120 psi cut-in pressure". When you say it doesn't shut off, does that mean it will generate 150 psi or more of pressure and fails to shut off or it develops less than 150 psi and does not shut off.

If the compressor does not generate 150 psi, then it is probably somewhat worn out and not capable of developing enough pressure to meet the factory high pressure limit. I would try adjusting the pressure switch upper pressure limit down to 130 psi or less (less if the compressor will not develop 130 psi) and see if this solves your problem If it doesn't,

If the compressor will develop 150 psi or more, then try adjusting the high pressure limit to less than 150 psi. If you can't adjust the high pressure limit then the pressure switch is defective and needs to be replaced.

Make sure the power cord is plugged into an adequate extension cord if one must be used. Never less than 12 gauge wire.

The start/run capacitor may need to be replaced.. If there are any ball check type valves, make sure they are not worn or sticking. they would be on the output of the compressor head itself.

If your compressor is oil-less type, most likely pressure is leaking past piston ring. To verify, remove cover to expose bottom of cylinder (unplug compressor and let out all air). With flashlight, examine the upper-most part of the cylinder (turn motor by hand till piston is at top of stroke). If top of cylinder is scratched, then pressure is leaking past.
For many years now, stores are in a race to have more HP and PSI to attract customers. Customer is really the loser because components used to make the units can not handle the higher pressure. Normally small 115v compressors are set to cut out at 125psi and larger two stage units will cut out at 160psi. Small compressor set to 200psi makes for short lived compressor. Could be compared to driving your car at 100mph all day every day. Longest life is attained when unit is being used at about 60 to 75 % of capacity.
To allow your compressor to reach cutout pressure and keep working for a while, lower cutout to 120psi (pressure switch may be adjustable). To restore to 200psi, replace cylinder/ ring.
If your compressor is oil type, suspect leaking reed valves.

A piston in any engine should be around 100 psi I would guess. A Chevy 350 used to be around 150 psi. An air compressor that only pumps enough air to reach 20psi is obviously too low on compression. Nailers and the like need 80 or more psi. The intake valves may be shot, the unloader might be stuck or piston rings are worn.

When the compressor comes up to pressure and kicks off, you should normally hear a gasp of air escaping. That gasp is the release of pressure from the compressor itself - not the tank, and it is supposed to get released so that the compressor can restart without being preloaded with compressed air. My guess is that the gasp is not happening. It is probably some debris or a gummy mechanism. The mechanism is supposed to be triggered by the same mechanism that shuts off the motor.

Sorry but this compressor will only supply up to a maximum of 130 psi. That is all it will do, so this compressor will not suit your needs of 175 psi. There is no way to make it produce more. You simply need a larger compressor. This Northstar compressor will suit your needs. http://www.northerntool.com/shop/tools/product_290954_290954
