Compressor runs normaly and builds pressure to 25-27 psi then motor slows and comes to a stop,if pressure is released from tank,compressor kicks in back in until 25 psi then slows and stalls again

This could possibly be, you have some water from condensation buildup inside the tank, liquid does not compress. Before this next step make sure the tank is to 0 psi! Now, there should be a relief valve Wingnut on the bottom. Loosen the wing nut and drain as needed. Then retighten the wingnut (Do not overtighten). Plug the compressor in and try it. My second suggestion is, the psi adjustment pressure knob could be faulty replace as needed!
Most likely in tank check valve is leaking or belt is slipping. Belt tension easy to check, should not deflect with thumb pressure. Check valve should not let air escape out of tank. Easy to check. Run compressor till pressure builds to around 50 psi. Then unplug machine from power outlet. Listen for air leaking out of tank. In bad cases, air will actually leak out of intake filter. Replace check valve as needed. Good luck
Whats happening is the compressor is trying to start with pressure on the head/ compressor. The motor is not strong enough to over come the pressure so the motor tries to run ,may be hum a little and pops the breaker. When you bleed the pressure in the tank down the motor does not have to over come the pressure and starts up as it normally would. Now, your problem is the check valve between the tank and compressor. It needs to be replaced. It is allowing pressure in the tank back to the compressor. Thus the compressor tries to start and can't. Trace the line from the compressor to the tank. You should find the check valve screwed into the tank and the compressor discharge line screwed into the check valve. Remove the compressor discharge line,then remove the check valve. Assemble in reverse . also you can loosen the fitting at the compressor. if it blows air all the time it's the check valve for sure.
Hi, Check to see if the switch will kick in if the pressure is released from the hose going to activate it...if so then the problem is the air being trapped between a check valve and the switch in the hose... I think that is your problem... There should be a way for the air pressure to change and represent the tank air pressure accurately.... The different compressors all have different ways of checking the air and then allowing it to release as the the tank pressure decreases..
There is a small hole there somewhere that is clogged with dirt and or oil...find that and clean it and you are in business again...
If you are using the air supply between when it stops and when it comes on again, then this might be normal. You havent mentioned what model/size compressor you have, but if is only a small 1-4 Gallon tank model, then these dont really hold a lot of air, and if you are using any air tool that uses a lot of air, you will be exhausting the tank supply VERY quickly, so the compressor fires up again to refill the tank.
If the compressor is only staying on for a split second after it fires up again, try plugging the compressor in directly to a wall outlet (ensuring the outlet is properly rated) and avoid using extension cords, which can leave the compressor with little power to overcome the tank pressure to kick over and refill. Compressors are best run directly connected to a main outlet, not via an extension cord.
There may also be a problem with the switching/regulating mechanism for the motor if it is jumping on and off in rapid succession. Check your regulator/tank pressure gauge. Take note of what pressure it kicks back on at, and what pressure it stops at. Many compressors will kick back in when the tank pressure drops to 80 PSI, and may stop when the pressure reaches 100-120 PSI.
There is a check valve between the compressor and tank, and there is also an 'unloader valve' which blows the pressure off the compressor so that it starts under little load. I think your check valve is stuck open and the unloader valve is blowing tank pressure off.. and when the compressor tries to start it's starting against the pressure in the tank.
So check/replace/thaw the check valve and you'll be good to go. It's generally at the tank where the line from the compressor head goes into the tank, it'll be between the two somewhere.
Hi, my name is John. Welcome to FixYa. Check your pressure switch, it,s only supposed to build up to 135 psi and shut off, then back on when the pressure gets below 105 psi, check the oil level. thanks for choosing FixYa. ..John
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.
