Compressor cuts off after 2 seconds

by Bill Taylor
(Kyle, Texas USA)

My Kobalt air compressor began cutting off after a second or two. It would try to start and then cut off almost immediately. After a few times doing this, it stopped altogether. When it stopped, I smelled an electrical smell like a short. Any idea what may be the problem? Also, how do you remove the plastic screws holding on the shroud?

Bill, I can't see the shroud, so I cannot tell you how to remove it, yet, remove it you should, as I suspect you've got a start capacitor that has failed or your unloader valve hasn't worked last time it filled up, and the added load has overworked your motor.

Dump the air from the tank, and try to start it again. If it starts, let it run up to cut out, and make sure that the unloader valve works. See UNLOADER VALVE from the site map for details.

If the unloader valve works, I'm guessing it is your start capacitor.

Cheers,

Bill

Your Kobalt air regulator is quite likely a standard, mini-compressed air regulator. This means that it is quite possible that you can buy a similar regulator at any shop that sells air compressor parts and components.

You first need to remove the existing regulator.

Make sure the compressor is unplugged, and drain all the air from the air tank. Leave the drain open while you are disassembling your regulator from the discharge air line. Don't forget to close the drain when you've replaced the regulator.

If you cannot see to disconnect the old regulator, it is possible that your model has a shroud with only the regulator gauge and adjusting knob showing. To detach the regulator, you do need, then, to remove the shroud first.

Cheers,

Bill
