Payne PG8JAA048070AAJA Air Pressure Switch
The actual job of the air pressure switch is to determine whether or not the primary blower is on and running. Most air pressure switches are designed with a reset that is manual instead of automatic, from which it would have to be reset manually before the system will continue its normal operation. This switch is part of all the safety features in today's HVAC systems in place to keep you safe from harm.
