I have a 3 gallon Husky portable air compressor.It’s been working great until about a week ago.

Suddenly while it was running (actually just on and up to pressure) it tripped a breaker in my panel and so I flipped the breaker back on but the compressor wouldn’t come back on.

I took the cover off and found the fuse had blown. I replaced the 3 Amp 250 V fuse and it blew it as soon as I turned on the power switch. I put another fuse in and it blew it.A friend and I took the head off of the cylinder and it’s fine.The motor is not locked up because we could turn it.

Any suggestions.Could it be a bad pressure switch or a short in the circuit board possibly?Thanks for any advice you can offer.



Is there a capacitor on the motor?

Sparse info there. Is there a circuit board?

Anyway, does is buzz or hum as it’s blowing the fuse? Does the motor have a capacitor?

If so it’s time to check cap(s).

Yes it has a circuit board.It doesn’t hum or make a buzzing sound when it blows the fuse.


Model # would be helpful

But, lacking that, I’d go ahead and check the cap(S) on the motor.

If they are OK, then take a look at the board for shorts/burned places.
