20 gallon IndustrialAir randomly blows breaker
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.
