Description
The York S1 024 39714 000 pressure switch is a genuine OEM HVAC safety and control component designed for use in York and compatible furnace and air conditioning systems. This precision pressure switch monitors negative pressure conditions within the system ( 0.90″ water column) and closes or opens its electrical contacts in response to airflow or vent pressure changes. Accurate pressure sensing helps ensure proper operation of draft inducer fans, venting systems, and safety interlocks, improving both reliability and energy efficiency of the unit during start up and normal operation.
