Kobalt K7060HFV will fill tank, but upon restart motor will turn two revolutions and STOP.

I have a 3.5hp 60 gallon Kobalt as listed which is being supplied with 240V, and the problem is as stated.


I purchased it used about 4 years ago, at the time it had only been used twice.

I finally put it in service and here's the issue.

It will fill the tank to correct 135psi and stop. When psi drops, the motor restarts but will only make a couple of revolutions and stop.

I can drain the tank completely and it will restart correctly and fill the tank. When it reaches 135psi I hear the air bleed of in the loud hissing sound for about one second. What's my next step?

Ray, thanks for the informative post and question. One more from me.

When the compressor stops, what stops it? Is the pressure switch tripping off, does a breaker blow, does the motor grind to a halt... what stops, please?

Jerry, not a lot to go on here. You don't indicate the model of your Kobalt air compressor, I cannot look it up to see what's what.

Tell me, as a comment here, what the pressure in the tank is when the compressor won't start, what is the normal cut in and cut out pressures, what HP motor you have, how you have it powered, and the modelf number, please.

We'll see if we can help figure out why your air compressor won't start.

Cheers,

Bill
