Description
The York S1-024-39715-000 Pressure Switch is a safety sensing component used to monitor air pressure conditions within combustion and ventilation systems. In HVAC systems, it verifies proper inducer motor operation and airflow before allowing burner ignition, helping maintain safe startup and operating conditions. Rated at 1.00 inch water column, the switch responds to pressure changes within the venting system and communicates with the control board to confirm correct draft performance. It is commonly installed in furnaces and heating equipment where monitored airflow and combustion safety interlocks are required for normal operation.
