Lennox XP19-030 Air Pressure Switch

Some particular air pressure switches can have a manual reset, by which you must manually reset it in order for the HVAC system to continue running. This pressure switch is one of the vitally important safety hardware devices made to stop injuries or explosions.
Precursors that the Switch will Soon Fail
