Bill, it could be a number of things.

Look under troubleshooting on the sitemap page, and follow the links to the pages about why an air compressor runs and won't build pressure properly for some tips.

1.5 hp compressor will not start with any pressure on it. why?

My 1.5 hp Sears air compressor will not start with any pressure on it

Hello Larry...

Could be a number of reasons for this to happen.

One of the commonest is that the unloader valve has not released the pressure over the piston when the compressor last stopped.

You can check this by opening your tank drain and draining all the tank pressure. Close the drain and try to start the air compressor.

If it does start and runs up to normal cut out, make sure that you monitor the unloader valve to be sure it is working.

If you want to know more about the Unloader Valve, see that page linked from the sitemap page under valves.

Hi Anthony...

If your Sears air compressor is under warranty, then cf course, request a replacement.

If it is out of warranty, do not necessarily assume that it is the motor at fault.

A too small extension cord could cause motor overheating, as would insufficient voltage in the socket into which you plug the cord from the compressor.

The run capacitor may have failed.

The pump assembly may have a problem and be back loading the motor to the point where it is overheating.

And yes, it could be that the motor has just worn out.

You must have some electric motor repair shops where you live. Take the motor there, ask for a motor test, and if the motor has failed, ask for an estimate for repair versus buying a new motor from them.

The new compressor motor only needs to fit the compressor and have the same HP and voltage, it does not have to be the same OEM equipment.

Cheers,

Bill
