York S1-024-27632-001 Pressure Switch Streamlined Installation: Designed for rapid

Streamlined Installation: Designed for rapid field attachment

ensuring consistent static pressure and reliable combustion airflow

it maintains HVAC actuator compatibility across a wide ambient temperature range from -40°F to 150°F

the high limit switch may be stuck open or tripped due to restricted airflow

the heater should be energized during the compressor's "off" cycle to maintain oil temperature

York S1-024-27632-001 Pressure Switch Streamlined Installation: Designed for rapidThe York S1 024 27632 001 Pressure Switch is a critical safety component designed for specific HVAC pressure monitoring applications. This factory authorized part is engineered with a setpoint of 0. 4" WC (Water Column) and utilizes a Single Pole Normally Open (SPNO) internal contact configuration. Unlike standard switches, this unit is built to close on a fall in pressure, ensuring precise control and system protection during negative pressure
