Description
The Modine 5H0735910001 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered to a 0.50″ water column (WC) setpoint. Designed for use in Modine heating equipment, this pressure switch plays a critical role in verifying proper airflow and combustion venting before allowing ignition to proceed — helping protect both the equipment and the occupants it serves.
How It Works
This pressure switch monitors the negative pressure generated by the draft inducer or combustion blower. When the measured pressure meets or exceeds the 0.50″ WC threshold, the SPST contacts close, signaling the control board that safe operating conditions exist. If pressure drops below the setpoint — indicating a blocked flue, failed inducer, or other fault — the switch opens the circuit and shuts down the ignition sequence.

Why Replace Your Pressure Switch?
A faulty pressure switch is one of the most common causes of heating system lockouts. Symptoms include the system failing to ignite, nuisance lockouts, or error codes related to pressure sensing. Replacing with the correct OEM part ensures accurate setpoint performance and restores reliable system operation.
