The reason for the existence of the pressure switch is to see if the blower is blowing air. This is one of the most crucial facets of the HVAC safety checks that are dedicated to keep you safe. Some pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation.
