Pressure switch doesn't kick off.

The pressure switch does not kick off when the compressor has reached its maximum pressure. The contacts weld together. The switch was burnt up and was replaced as does the same thing.

Scott, it's odd that you had the same problem with two pressure switches. Really odd.

You don't indicate your compressor voltage, but I assume you got the pressure switch that suited the voltage?

That being the case, I suspect a faulty re-wiring. Is this possible?
