My air compressors does well until the pressure drops below 100, then even at 90 it won't charge back up and i can't figure out how to build the pressure back up.

If you drain the tank down way below 90psi and somehow you get it to come back on, the the regulator switch has a minimum that is set too low. Without knowing the specifics, I can't be for sure. I had a 1/2hp 15gal. once and the regulator has a screw that could be turned clockwise and it would increase the operating pressure. Consult your owners manual to make sure you don't go overboard with this adjustment.

Sounds like your a/c compressor is worn out. When the internals get sloppy, they won't build pressure.

Craftsman air compressor model 191.135131 wont build pressure


I can not find a Craftsman compressor with that model number anywhere so here are a couple things to look into. If the compressor fills to 70psi and keeps on running check the valve plate and piston/cylinder assemblies. Check that the valve reeds on the valve plate are not bent, broken or warped from heat. Then check that the wiper (oil less) or pistion rings (oil splash) are not damaged and that the cylinder wall is not scarred up. Any of these will let the compressor fill up to the point where the air pressure leaks past the valves or piston and won't fill any further. If the compressor fills to 70psi then shuts off the problem is in the pressure switch. Some have an adjustment screw or bolt to control when it turns on and shuts off. If you had a drop from 100 to 70 the springs may be weak or broke and you'll have to replace the switch.

There is a problem with your pressure switch. You should have a little black box with a red lever to turn your air compressor on and off. This housing contains your pressure switch, the pressure switch sends an electrical signal to the switch to make your air compressor run. When enough pressure builds up the pressure switch activates, and breaks the signal until the pressure drops below a certain point. I will do some more research on your compressor and find out which pressure switch you need to order. i need you to find any numbers on the compressor you can, serial number, model, stock number, anything you can to help me find the part number.
Thank you for patience,

Run the compressor until there is about 75 psi in the tank and turn it off at the pressure switch. Remove the black bleeder line from the pressure switch:
1. If absolutely no air comes out of the line you may have a bad start capacitor on the motor. Have it tested at an electrical or refrigeration shop or just replace it to see if it takes care of your problem.
2. If you get a short blast (five or so seconds) of air then nothing your pressure switch isn't letting the head pressure bleed off after the motor shuts off. This pressure has to be relieved or the motor has to fight the tank pressure when it tries to restart. Reconnect the bleed off line and turn the motor back on. If it starts normally, replace the pressure switch. If it struggles or won't start it is more indicative of a bad start capacitor.
3. If you get constant air flow from the bleed line the problem is with your tank check valve. This causes the same problem as above. Replace the check valve.

IT depends on the tool. Some tools require higher cfm. (cubic feet per minute) of air. IF your air line is not large enough, then sometimes 90psi is not enough to operate a tool as there is a pressure drop at the tool. Look at the required cfm for each tool. Find a chart for air line size, cfm and pressure. Most impact wrenches should be used on a minimum 3/8" air hose. You could look at your manual and see what the max pressure is on your compressor. You may be able to decrease the differential pressure e.g off and 100 and on at 90, but then the compressor will cycle more frequently, and may exceed the duty rating of the compressor.

It sounds like maybe an overload for the compressor is tripping and resetting once the compressor cools. Possibly due to a low charge.

I have a model FP209501 Air Compressor 2 Gallon,


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

Adjusting the pressure on the 2340-E


most air compressors have a pressure switch on them.this is used to adjust the desired pressure you want to reach.the second adjustment is for setting the pressure for when you want it to cycle back on.lets say you want it to run at 100 PSI.one of your adjustment in this box will control this , when you are using the unit and the pressure starts to drop to lets say 90 PSI you can adjust the unit to cycle

I have a new Puma La5721 and when I adjust the pressure to 120, it drops back to 90 and starts running aagain,after releasing pressure from below the switch box. Am I doing something wrong.


yes buddy it will do your adjusting the stop pressure so say you set it too 150psi once it reaches this pressure it will stop then as the pressure drops to about 120psi the compressore will restart and build to 150 again and you can adjust the starting pressure

TRY ADJISTING THE TANK PRESSURE KNOB WHILE RUNNING ,TURN TO THE RIGHT 1/4 TURN UNTILL YOU SEE NEEDLE MOVE .MOST TIMES FACTORY SETS AT 0,SO YOU NEED TO ADJUST IT .MY ADVICE IS NO MORE THAN 90-100 PSI TILL YOU KNOW WHAT YOUR RUNNING MORE OFTEN
