221565 Kobalt motor hums and kicks out
by Jerry Schleicher
I have a model 221565 Kobalt air compressor. It's about 4 years old. When I turn it on the motor only hums, so I removed the belt guard and spun the compressor pulley while it was turned on. It started and pumped up to 165 pounds and shut off. I let enough air out for it to start again and it just sat and hummed again until the motor tripped. Can the motor be shot after only 4 years and minimal use?
