My compressor keep turning off!

by Linden
(Red Bluff,CA USA)

When I start up my 47065 it runs for a short time and then turns off and I have to wait for a while when I hear a click and then punch the red button on the side of the compressor that had popped out. It will run a short time and do it again. I must keep doing that to get the pressure up so I can use it. Help!

47065 keeps stopping
by: Bill

Linden, from what you've written it sounds as though the compressor is cutting out on thermal overload.

This is often caused by a power supply problem.

Anything new in your power supply to the compressor - new socket, longer extension cord, and is this a new issue?

47065 not run more than 1 or 2 minutes before tripping

by Jeremy

Hi.

My 47065 will run for about a minute or two and then shut off. If I wait and then press the black (circuit breaker?) button it will run again for another minute or two. If I bypass the "circuit breaker" it will continue running to 120PSI as it's supposed to. I have checked the amperage draw while doing this and it's near 17 amps that the unit is drawing. The unit is rated for 14.6 amps continuous. Off the top of my head I'm guessing the brushes in the motor need replacing. Does this sound correct to you? And if so, are the brushes easily replaceable on this motor. Any idea what size and spec brushes I need and where I can find them? Thanks.

Better quality Ckt Bkr

Better quality Ckt Bkr I got from the internet rated 20A is working Awesome now for 2 mths straight :) PS set to 125 psi I'm getting away with now. a little higher than orig spec & I did install a newer better quality PS last year. seems my compressor is getting better with all these improvments. just drain 2x a year and top off oil periodically. had mine since 2003 HF Nat City,SD

47065 tripping breaker
by: Bill

According to the manual I have the 47065 is powered by a 3 HP Working / 120 Volt / 60 Hz / Single Phase / 12 Amp motor.

Before I started tearing down the motor to check brushes, assuming your motor actually has them, it were my compressor I'd be checking both the start and run capacitors first. See the page on this site about how to do that.

Wayne, as a comment here, please tell us about your compressor power supply. Extension cord used? Power bar? Amperage of the circuit breaker for socket you plug the 47065 compressor into? How many other items are pulling power from the same circuit... this type of stuff.

If the reset button you refer too is the thermal overload protector for the compressor motor, then by resetting it too frequently, you may be causing the motor to overheat to the point of damage.

That your compressor motor is over heating suggests a power issue, at least, let's rule that out first.

If the power supply to the compressor is clean, then it were mine, I'd be checking the run capacitor next. You can see how on the page on this site.
