20 Most Recent Craftsman 150 PSI Air Compressor Questions & Answers

The pressure regulator on an air compressor is designed to let the pump motor run until the pressure in the tanks reaches their safe level. While you are using the air the pressure drops in the tanks until it reaches the level where the pressure switch turns the motor on again and refills the tanks to their rated level. The pressure where these two things happen is usually with in ten psi above or below the rated levels because few regulators are so precise and are affected by temperature that they turn and off exactly at the rated pressures. If a pressure regulator is damaged or broken it is possible for the tank to either reach unsafe high levels or not turn on when the pressure drops to where it should restart the motor. If you are in doubt, have the regulator checked or replaced as overpressured tanks are very dangerous.

Could be weak thermal cutout or actual problem with unit. Thermal cut out easy to check with amp meter. Connect meter as required to monitor draw as unit fills and make sure that it stays at or below usage stated. If amp draw stays below stated usage and thermal cuts out, replace the part. If amp draw goes over amount stated turn off compressor and listen for air leaks (usually check valve will leak back pressure to pump causing extra load on motor).

be a little more force full the spring is suppose to pu a lot of tension on the knob so the the setting doent change with the vibration. just make sure you push down ans start it straight.

Question edited for clarity. Question moved from Misc to correct category. By 'stride wire', do you mean just short across the switch? Yes you can but really you need to fix the problem. You know these things can blow up and spray shrapnel 30 feet? Google Craftsman (model) parts You may have a short in the motor, in which case, shorting it out won't fix it. https://www.google.com/search?q=Craftsman+Air+Compressor.+I+have+to+press+the+reset+button+on+it

regulator is bad, or tank is not low pressure. you could return it for another one.

capacitor weak --motor drawing to many amps if using extension cord[s] not correct or to far from source and causing to much voltage drop -motor faling--compressor failing

That model number only shows in this post. I don't see how a compressor can be 'oil-less', the friction and pressure is enormous! https://www.google.com/search?q=6.5+HP+oil-less+60-GAL+MOTOR+%22K56A28B23%22 ..

is the plunger sticking below the housing . if so push it back in with a screw driver

Craftsman Electric Stapler Model #193.684231 aka 9-68423. (Came out in 1984) Can take up to 5 different size staples depending on your project. One feature is the "dual power" knob at the top which allows you to use "HI" or "Low" impact depending on the size staple used. Sorry about the blurry pictures, they are sharp on my computer. Try Googling the model number or looking on EBay. "No. 6" means "Heavy Duty Wide Crown .417 size."

I have 351.181720 and the driver does not return. I've had this for years but it has not seen extremely hard use (probably less than 500 brads). Suggestions. [email protected]

Either the compressor or the motor is defective.

Either the unloader valve on the pressure switch is bad or the extension cord is too long or the start capacitor is weak. When the tank is full, unplug and try to turn by hand a few turns. Air should come out the unloader valve drain fitting.

replace the faulty poppet valves in the compressor heads
