Modine 5H0794410003 Pressure Switch Technicians should perform a continuityWhen you're dealing with a Modine unit heater that isn't cycling correctly, the Modine 5H0794410003 Pressure Switch is a frequent point of failure. This OEM component is a . 63" WC Pressure Switch designed specifically to monitor the pressure differential across the heat exchanger. It functions as a critical safety limit, ensuring the power exhauster motor is moving enough air to safely vent combustion gases before the gas valve is permitted to open.
