My husky 2 gallon air compressor is not building pressure. The motor runs but no pressure build up. Cannot detect any leaks. what is the problem?

Check all connections with leak detector or a soapy water mixture for any possible air leaks.

when i turn it on motor runs but it will not build up air pressure

Is there an option for you to run this compressor on 220 volts vs 110 volts??? If so, you may want to convert it by following the re-wire instructions on the motor or wire access plate/instuction book. The reason your compressor won't fire up again after building pressure is the head pressure is to great at restart and 110 household current is not enough to give the power needed to turn the piston. You'll need to replace the plug and have someone run a 220 volt circuit once the conversion is completed.

First check the check valve and also if it has an unloader valve make sure it is closing.

The main check valve is often right where the air goes into the tank. The unloader can be integral to the pressure switch or on the compressor.

hi buddy can be the valves sticking try squirting oil in the air filter and get back to me

it sounds like the regulator is out of whack turning down increases air pressure. make sure there is no leaks

Your manual pressure release valve might be stuck open or blocked open by some debree. It should have a steel pull ring on the end of it. Exercise it and try running it again. Also the pressure regulator adjustment might have been backed off to zero. Crank it clockwise and see if this helps. Check the air output lines from the compressor to the tank for leaks.

First remove the valve using probably about a 1/2" wrench but make sure there is no pressure in the tank before you do so. check the cone and seal by loosening the valve by hand and check for debris. If there is no debris then the problem is either the pressure relief valve or weak pressure regulator but may also be a bad piston seal if it is a direct drive unit.

Check the reset button on the motor to see if it tripped. The motor may be overheating. Some motors have an internal breaker and they have to cool off before they restart. Also check the pressure switch. Move the switch back and forth ( on and off ) and listen for a click. If it doesn't click with low to no air pressure then the switch is bad.
