It can be that the pistons are weak , there is leak somewhere to let the air off or the drive belt is slipping.
So have the oil checked , the direction of the cycle must be correct to pressurise as it can be felt in each cycle..

My bosch ksu 40600 keep switching on and off


It\'s called a short cycle. Most of the time, it means your compressor is about to fail cause your head pressure is to high and cuts out on the high pressure sensor, or your thermostat has issues or if your lucky, your low on freon and it cuts out on the low pressure switch. The unit when the compressor is not running, the pressure equalizes and runs around 30-70 psi, give or take a few. When the thermostat says it\'s too hot in the box, it turns the compressor on. When it does that the freon is pumped and as it gets the coil colder, the pressure drops and if there isn\'t enough freon in the system, then the pressure falls below the set point and the pressure switch shuts the compressor off. I wouldn\'t let it run like that as it\'s hard on the compressor and left running, will shorten the life of the compressor.

My kobalt air compressor model#215914 won't stop running is it suppose's do that?


All compressors run up to their rated high pressure level, usually listed on the data plate on the compressor or in the manual, then the pressure regulator turns them off. If your compressor is not shutting off it is either not getting to the pressure it takes to get the pressure regulator to turn it off or the pressure regulator is broke and won't turn the motor off. To check which, turn the compressor on and watch the guage that shows tank pressure. If the pressure rises then stops at a level below the rated pressure for your compressor and the motor continues to run, you have a leak somewhere. It could be the tank drain valve, the lines from the pump to the tank, the valve plate or in the piston cylinder area. If the pressure rises more than ten psi above the rating for your tank, your pressure regulator is broke or possibly set too high. If you know how, you can try lowering the shutoff point to see if that fixes it but you're usually better off replacing the regulator.

Coleman POWERMATE Lo502710. Compressor runs and builds up pressure and then keeps on running even when 100 PSI. It will not shut off. I do not hear a leak when I pull the electric plug to make it stop...


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,

Dewalt air compressor keeps running until pressure output is 200 PSI, the same pressure in the tank. Why doesn't it quit running at 120 PSI the designated pressure on the compressor?


The regulator switch/unloader is bad or out of adjustment. Perhaps though the gauge is faulty. 200 psi in a 120psi compressor is dangerous, don't run it until it is fixed!

I HAVE A CRAFTSMAN 1 HP 12 GAL AIR COMPRESSOR THAT WILL ONLY BUILD 20 PSI THE COMPRESSOR ONLY HAS 1.5 HRS RUN TIME ANY SUGESTIONS


hi there, if the compressor built up a 20 psig and run at 1.5 hrs.then stop.check the pressure switch the differential pressure cut in and cut out limit.adjust the cut out to the corresponding cut out pressure you want but not exceed to the designed pressure tank..this will be done on adjusting cut out pressure screw mounted inside the pressure switch.follow the instruction on the manuals adjusting pressure switch.the run time correspond to the cut out limit of the pressure switch. rate my fix if your satisfied thank a lot.

Compressor has no oil pressure but seems to be running good


If you're sure its not just a bad oil pressure gauge, and there is no pressure, the oil pump is probably bad. If you don't run it hard, it may still last awhile, running more like a "splash lube" compressor. Still, if this is a pressure lubed Quincy, it's a good compressor - I'd fix the oil pump and it'll last for years.

Portable oiless compressor wont pressurize


If there is pressure at the pump, either:

1) The tank check valve isn't opening (it's located where the line from the head enters the tank - usually extends into the tank, and the the pressure switch unloader line comes off of it as well)
2) The pressure switch unloader is bleeding off the air. This is a small valve on the side of the pressure switch. It should close when the compressor is running and open when the compressor shuts off to bleed off head pressure.

DeWalt emglo compressor does not start


hello,
well,you have to release the pressure,the cut out pressure at 120 psig.reached,and the cut in pressure maybe at 40 psig.so after realeasing pressure at cut in the compressor will run.if the compressor not run at cut in or after releasing check your power supply if still have,swicth off power breaker,by pass pressure switch,by disconnecting the line on terminals of pressure swtich,connect the line w/out pressure switch
the wire line should supply the the compressor,
open the service valve of compressor,switch on
observe if compressor run and develop pressure or air is coming out to nozzle,if that so switch off again and replace pressur switch.you have defective pressure switch,regards rate me,thanks

EC-12 runs but only builds to 35 psi and continues to run


It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.
