20 gallon IndustrialAir randomly blows breaker

by Mike
(Madison, WI)

I have a 20 gallon HP IndustrialAir model IL1682066 belt drive oil lubricated compressor that will randomly blow the breaker.


At times it works fine but others it will start making a vibrating noise and then blows the breaker.

This can happen at startup or sometime after it has been running.

What I have been doing is when it starts making the noise I will immediately turn it off and back on repeatedly until it no longer makes the vibrating noise. It will then work fine for a bit but then do it again.

This is a low-use compressor that was purchased 3 years ago but gets used only once a month. The issue started just after the warranty expired.

Well, it's not INvalid.

And then if that seems OK, you can further try it with the drain valve open. Or even just try it that way to begin with.

Any new information may be relevant.

For instance, if it still blows no-load, that suggests possible wiring issues.

Might be good to invest a few bucks in a clamp-on ammeter so you can see what's going on with the current BEFORE it blows. HFT, for E.G., has a couple for well under $20.

Thank you all for the suggestions.

Do you think it would be a valid test of the motor to remove the belt and see if it reacts the same way? I assume that the best test is when the motor is under load.

I will also test the capacitors and look at the centrifugal switch and see if I can find any issue. There is a nice YouTube that shows me the basics on what to look for.

I called and was pretty much told that since it was no longer under warranty they couldn't help. They only suggested that I buy a new motor and hope that would fix it. Since this was for all intents and purposes a brand new compressor I was hard-pressed to dish out another $100 or more in the hopes it fixed things.

You might also want to check the wiring in the motor and the capacitors. Caps can fail intermittently and/or slowly, which might give your symptoms.

If this compressor motor has a centrifugal switch, that might be the cause. It is supposed to transfer power to the run windings in the motor from the start windings after the motor gets up to speed. If this is the issue, you need a motor repair.

Before you get the motor checked, have you contacted IndustrialAir?

For all parts and service related requests please feel free to call us at 888-895-4549.
