Description
Modine 5H0730570005 300°F Manual Reset Blocked Vent Switch
The Modine 5H0730570005 is a genuine OEM blocked vent switch engineered to protect Modine heating equipment from dangerous flue and vent blockage conditions. When the sensed temperature reaches 300°F — a threshold indicative of restricted or obstructed venting — this safety switch interrupts the burner circuit and locks out operation until the root cause is resolved and the switch is manually reset. This manual reset (M/R) design ensures that a qualified technician inspects and clears the vent obstruction before the unit is returned to service, preventing repeated unsafe cycling.
