Modine 5H0794410002 — 0.70″ WC SPST Pressure Switch
The Modine 5H0794410002 is a factory-specified Single-Pole Single-Throw (SPST) pressure switch designed as a direct OEM replacement for compatible Modine heating equipment. Set at a precise 0.70″ water column (WC) set point, this pressure switch monitors air pressure within the system to confirm proper draft inducer or combustion air blower operation before allowing ignition to proceed — a critical safety function in modern gas-fired heating units.

Application
This pressure switch is engineered for use in Modine gas-fired unit heaters, cabinet heaters, and other Modine heating systems that require draft-proving pressure control. It ensures the heating system only fires when adequate combustion airflow is confirmed, protecting the heat exchanger and occupants from unsafe operating conditions.
