Kobalt 8 gallon compressor won't power off when it reaches 150 psi


When the tank pressure reaches 150 psi, the unit is supposed to power off. It does not.

Instead, the pressure release valve releases the pressure, and the unit stays on. This happens over and over.

I replaced the pressure switch, but nothing changed.

Any thoughts?

A thought about your Kobalt not powering off...

Unplug it...
Try removing one and then the other wire from the pressure switch. Make sure the wire can't touch anything. Plug it in, turn it "on". Does it run?

Please let us know.
