reason, the thermal overload protector will shut it down in order to prevent the motor from being damaged.

to start up or shut down automatically, without warning, upon air demand.ALWAYS set this switch to OFF when
the compressor is not being used and before unplugging the compressor.

level of the motor, it will automatically pop open. You can also pull the ring on the valve to open manually.
