6.4 HP Ingersoll Rand Compressor Motor just hums
by Randy Bragg
I was using my compressor yesterday with my nail gun.... I noticed I lost pressure so went to check.. My compressor had tripped the breaker and when I turned the breaker back on and turned it on it would just hum... I also noticed that the on off switch on the compressor arched when I turned it on... Any idea where to start? it is a 80 gallon ingersol compressor with a 2 year old WEG 6.4HP motor on it.... Motor and pump do turn....
