Modine 5H0794410012 — 1.54″ WC Pressure Switch
The Modine 5H0794410012 is a factory-specified pressure switch designed as a direct OEM replacement for compatible Modine heating equipment. Set at 1.54″ WC (inches water column), this pressure switch monitors draft and combustion air pressure to ensure safe and proper unit operation. If the required pressure differential is not achieved — indicating a blocked flue, failed inducer, or venting issue — the switch interrupts the ignition sequence to protect both the equipment and occupants.
