Husky pancake compressor won't fill

Are you meaning that you cannot adjust the regulator to change the pressure output?

Try heating it with a torch and use PB Blaster on it.

If it's an oil-less, none. If it's a regular compressor, use compressor oil.

You have to replace defective hose. Buy and fit a better / higher pressure range to prevent this condition. Check also all your hose connector for malfunction.

I could not find parts for my husky compressor and had the same problem as you describe. I went to lowes and purchased fittings to draw air out of the safety port. Remove the safety pop valve and install t-fittings to allow you to reinstall safety valve and also a quick connect. If you want to be able to regulate the pressure, install a simple pressure regulator before the quick connect (also avail. at lowes). This remedy is not pretty but sure works great and simple. Problem with husky regulator is stripped thread /knob. Sometimes you can turn the knob if you drain air from tank; this will release the spring tension on the regulator knob.

Is it plugged in?

the outlet ur plugged into the amps are to low when compressor tries to restart under load which draws more power than what the circuit breaker is rated and or their are other things plugged in on same circuit drawing power and causing the higher amp draw-- plug into some other circuit preferably with nothing else plugged into the circuit or with a higher amp [20amp]breaker

I am a little confused here ... I have a Craftsman pancake, a Craftsman 6 hp (same compressor design) and several other name brand pancake compressors at the job. The compressor doesn't care which way the motor runs though mine all run in the same direction. As long as the piston goes up and down, the reed valves know when to open and when to closed based on the pressure. It sucks in from the 'room' on the down stroke and blows into the tank on the upstroke.

Yours isn't doing this? If it is creating a vacuum in the tank, I would have to say someone put the valves in upside down.

This is very curious.

You could reverse the black and white wire but as I understand the physics of it, it will not matter where the hot wire is since it is AC. The motor may be reversable but I'm thinking it is probably not in this case. That costs extra to make into the motor.

Please inspect the valves to make sure they are capable of 'inhaling' (the site will delete the other word I used) on the down stroke and 'exhaling' into the tank on the upstroke.

Please let me know what you find out.

Thanks for your curious question at FixYa.com

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.

the regulator may be turned down, find the regulator turn it to the right to allow air into the tank, tank must have air in it to deliver air
