Mastercraft Air compressor humming does not start

by AP
(Oakville, Ontario, Canada)

My 5 gallon air compressor started not getting to full pressure and after around 90 psi it would start humming and not moving any more.


Now our is not even running, when I turn it on, or starts humming immediately, so completely down now.
