A defective capacitor could definitely be the cause of you motor humming when trying to start. You may want to inspect the windings of the motor, to make sure that they are not burnt or a darkened and if you can smell any burnt insulation. If they are that could be the source of your problem.
Hi, I'm needing a better pic of the head assembly for Dewalt 55153 Type 3. Connecting rod was broke and I'm trying to reassemble but can't find a decent photo anywhere for correct assembly of the head plates and blades.
My dewalt d55153 type 3 air compressor does not ac***ulate air. The motor runs, but the tanks remain empty. Please help. Ive check the drain valve, i checked for leaks from the hoses, but have not opend the unit.
most likely you have a cracked reed valve. remove the supply tube, with it running, see if any air is coming out of the head, if it had been running remember that tube will be hot. if it is not pushing out any air then most likely you have a broken reed valve. hard not to tear gaskets when opening so you may need whole kit including the gaskets
DeWalt 55153 compressor starts right up. Runs till full, will not start again as you draw air, it does try, until the breaker trips. I can make it start again by pushing in the cold start valve needle, which I replaced to no avail.
