How old is this compressor? The trouble with mine of the same design was blow by ... the rings were just worn out. I found it cheaper to replace the compressor than make the repair. You might find the repair is more economical. Call C/H parts for prices. Should be a toll free # in your owners manual.

Thanks for your interest in FixYa.com

My Porter Cable pancake air compressor is getting too hot and melting my air hose


ASSUMING THIS IS AN ELECTRIC MOTOR DRIVEN SINGLE STAGE COMPRESSOR, IF THE COMPRESSOR USES OIL IN THE CRANKCASE, THE PRESSURE SWITCH SHOULD CUT OFF AT 125 PSI AS THE ACT OF COMPRESSION HEATS THE AIR QUITE HOT. THERE IS ALWAYS SOME OIL THAT PASSED THE PISTON RINGS IN THE COMPRESSED AIR. IF THE COMPRESSED AIR GETS HOT ENOUGH, THE OIL VAPOR CAN IGNITE AND THE FLAME CAN CARRY TO THE TANK FOR AN IMPRESSIVE EXPLOSION. THIS ORDINARILY DOES NOT HAPPEN BELOW 175PSI OR MORE.

OILLESS COMPRESSORS CAN BE SET TO 150 PSI. WITH EITHER TYPE OF COMPRESSOR, THE HOSE SHOULD BE ATTACHED TO THE REGULATOR OR THE REGULATOR STACK, NEVER TO THE COMPRESSOR, AS THE COMPRESSED AIR LOSES MUCH OF ITS HEAT WHILE IN THE RECEIVER. IF THE WHOLE TANK IS GETTING HOT ENOUGH TO MELT A PROPERLY ATTACHED HOSE, YOU HAVE A DANGEROUS SITUATION, CHECK THE OPERATION OF THE PRESSURE SWITCH, UNLOADER VALVE AND RELIEF VALVE. THE RELIEF VALVE SHOULD OPEN AT NO MORE THAN 150 PSI, THE UNLOADER VALVE OPENS WHEN THE PRESSURE SWITCH SHUTS THE MOTOR OFF, AND SHOULD ONLY HISS FOR A FEW SECONDS AS IT DUMPS THE PRESSURE ONLY IN THE COMPRESSOR AND THE LINE FROM THE COMPRESSOR TO THE TANK INLET CHECK VALVE. IF THE UNLOADER VALVE HISSES MORE THAN A FEW SECONDS, THE TANK INLET CHECK VALVE IS LEAKING AND NEEDS TO BE SERVICED, CLEANED OR REPLACED. IF THERE IS CARBON BUILD UP IN THE VALVE, THERE IS EXCESS OIL PASSING THE COMPRESSOR PISTON RINGS, REPLACING THEM MIGHT FIX THAT IF THE CYLINDER OR RING LANDS ON THE PISTON ARE NOT TOO TAPERED OR WORN.

Wont build up air.What could be the problem


leaking pressure hose from cilinder to tank leak pressure switch a dirty check valve on the tank open it and look for a smooth clean rubber valve that can free move and no metal pieces in it if that is there found then a part in the hose line or membrane plates are broken , if you have a dry(oilless) compressor the piston ring and cylinder may be worn.
Several possibilitys depends on models The pressure reducing valve can also be faulty leaking drain at the bottom of the tank leaking the safety valve must be good closed and also the little pressure release unit the small black hose oft in many models in the pressure switch must be closed by start there can also some dirt comes in. .that it will not close and then its continu blow of normal you can hear that it closed by starting and always release the pressure air for the next start .

Husky air compressor


Josh:
Your compressor shouldn't run more than ten to fifteen minutes before shutting off. The pressure should be posted on the machine somewhere ( a decal usually says xxxpsi). You evidently have an air leak somewhere. On the bottom of the air tank there is a valve for draining the tank of air and any moisture. Make sure to close that valve by hand only (Screw it in all the way by hand and remember, you are working upside down, so don't get confused as to which way to turn it). If the valve will not unscrew to drain the tank, you can use a pliers to loosen the valve to let the air out, but be sure you are turning it in the correct direction or you'll break the drain valve!! Now that you have the drain valve closed, turn the compressor on and watch the pressure gauge. When the pressure gauge reads the pressure on the decal, the machine should turn off. If the pressure gauge stops climbing before it reaches the specified pressure, you have an air leak somewhere. You can either feel for the leak at the air line connectors by hand or mix a dish soap and water solution the pour on the air line connectors to look for the leak. Keep the soap solution away from the motor!! When you find the leak, drain the tank using the drain valve at the bottom of the tank, disconnect the hose coupling that is leaking and wrap Teflon tape around the threaded portion of the male end of the fitting (3 wraps should do it) and reconnect the coupling ( tighten it well). Close the drain valve and start the compressor again. and check all fittings for leaks again.

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.

I HAVE A C/H OILLESS COMPRESSOR, DIRECT DRIVE...THERE ARE NO OPEN VALVES OR LINES AND NO UNUSUAL NOISES...HOWEVER, TANK PRESSURE WILL NOT RISE ABOVE 20#. WHAT TO DO?? RICHARD


Your unit should fill within 5 min. Compressor may have worn cylinder or just leaking. Easy test. Spray soapy water on all connections/fittings including drain valve and regulator while compressor is running. Repair as needed. If no leaks, remove plug from outlet, remove cover and examine cylinder. Turn crank by hand till piston is all the way up into cylinder. Examine carefully the condition of the cylinder close to top. If the cylinder is scratched or worn then pressure is leaking between piston/cylinder and will not fill tank. Replace cylinder kit available at www.chpower.com, cost under $50. Good luck with your project.

A DIRECT DRIVE COMPRESSOR & THE PRESSURE SWITCH IS FAULTY


STOP! Your pressure switch is doing what it is supposed to, but the tank check valve is leaking. This valve is usually at the tank where the line from the compressor head enters the tank. The small tube line from the pressure switch probably also goes to this valve. You'll need to clean or replace it.

Bostitch pancake oilless gets pressure in the tank (ie. I can let air out of the pressure release, but the hose connection does not get air.


Probably one of four things:
1. Bad quick disconnect fitting (though these usually fail open (leaking)
2. Bad Regulator (if equipped)
3. Check for a shutoff valve on that line (sometimes they are integrated into a plastic manifold, and may not look like a traditional valve)
4. If the unit is older, rust may have plugged up the piping - you may have to take it apart and clean it. (Depressurize first - there should be a drain **** to relieve the pressure)
