SOURCE: Hi, I have a colt Mk 282 air compressor that won't

The shutoff valve (usually has a set of contacts like a relay) is probably stuck. For the most part, these are not adjustable. They can usually be removed, cleaned, and reinstalled to correct the problem. Sometimes that permanently fixes it. Sometimes, you have to bite the bullet and by a new shutoff valve.

SOURCE: Electric Air compressor just hums then trips breaker.

usally there is a releaf valve that takes the pressure off the compressor while it is resting. If that pressure is not off when the drive piston starts the motor will overload and blow the the breaker or reset. Check for a releaf valve for when the unit has reached full pressure

SOURCE: kobalt air compressor will not go above 80PSI

if this is an older or much used unit, cylinder/piston may be worn, unable to push higher psi, which would explain no leaks. if newer unit, seems like regulator unit/valve faulty

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

Remove the screw of the top of the compressor, turn on the compresser and allow it to charge. By keeping in mind note the pressure on the pressure gauge when the compressor turns off. Release the air from the pressure tank and watch the pressure guage and make a note of a point where compressor on.

I have a craftsman air compressor model number 921.153101 that won't pump-up over 40 pounds

Its probably a oil less compressor so it could be the reed valves are bad or the piston rings are bad.

I have ABAC 270ltrs italian comprosser. after the comprosser reaches its full capacity air starts to leak from its switch. can u pls help me solve this promblem

In 80% of the cases this is the problem. I sulose that you use a lot this compressor so the one way valve gets worn out. The first stel is to pull out the smal hose when the unit stops and see if air escapes. If so then change the black piece in the photo. It will last for a small period of time. I recomend to change the piece in the photo.
This is a way to solve the problem if air escapes trough the small hose.7

That is an extremely high pressure. I would firstly check to make sure that THAT is what you need, then MOST compressors have a regulator where you can adjust the pressure required.
It is not so much the pressure you need as the STORAGE of air that you need for a pressure that high. MOST tanks are around the 20 or so litre. To utilise a tool requiring the pressure of 75PSI I suspect you would need a tank of somewhere around the 2-300 litre size or maybe even bigger. But first just make sure that you DO need the 75PSI you mentioned.

Compressor motor only comes on and fills tank when tank is empty. When tank has any pressure it tries to start but stops.

there is a valve under the regulator, at switch off pressure the valve must blow of the air between cilinder and checkvalve after stop running.. when checkvalve is not closed it keeps blowing.

My 25 litre air compressor builds up to 120 psi,but dont seem to release maximum pressure

You should have two pressure gauges. One will tell you the tank pressure and the other is the outgoing pressure. There should be a plastic knob that you can pull out and turn clockwise to increase or counterclockwise to decrease. Also try a different hose as there may be some debris in the hose.
Hope this helps

2 gallons is small to begin with u need to buy an in line pressure adjuster/regulator their a few bucks and can be attached to the paint gun or line and will keep the pressure at ur adjustment the regulator on the tank sets the tank pressure at 50 so when u us it will let it drop down to about 45 than start up to build the pressure up to 50 than shuts off than repeats it self the inline keeps pressure steady even if tanks are at 200 psi
