Modine 5H0730570005 Vent Switch

Replace a failing or tripped safety sensor with the Modine 5H0730570005 Vent Switch, a critical component engineered to maintain the operational integrity of your heating system. This blocked vent limit switch is a manual reset safety device that monitors exhaust temperatures, specifically designed to trip and interrupt the electrical circuit if flue gases exceed 300 degrees Fahrenheit. As the direct cross version of 5H73057-5, this OEM replacement ensures seamless HVAC part compatibility for veteran contractors servicing Modine gas heaters, including the BAE, CX, FX, and GHE series. By detecting restricted airflow or flue spillage, it prevents hazardous combustion gases from entering the space. Built with a robust ceramic housing to withstand high-thermal stress, the 5H0730570005 is a high-reliability safety limit switch for industrial and commercial unit heaters where system uptime and technician-level safety standards are non-negotiable.

• Precise Thermal Monitoring: Actuates at 300°F (L300F) to protect equipment from overheating during blocked vent conditions.
• Field-Proven Durability: Features high-temperature ceramic construction that outlasts standard plastic versions in high-heat zones.
• OEM Standards: Direct manufacturer replacement for part numbers 5H73057-5, 36TX16, and 6267, ensuring exact fitment.
• Manual Override Security: Requires a physical reset by a technician, mandating a system inspection after a trip to ensure the cause of high flue temperatures is addressed.

What causes this vent switch to trip in Modine unit heaters?
Tripping is typically caused by inadequate vent draw, excessive vent run length, restricted vent terminals, or negative pressure within the room preventing proper exhaust flow.

Can I replace a 220°F switch with this 300°F 5H0730570005 model?
No, always match the temperature rating specified for your specific heater model. This 300°F switch is calibrated for units with higher exhaust profiles; using an incorrect rating can compromise safety protocol.

Is the 5H0730570005 compatible with the Modine Hot Dawg series?
This part is primary to larger BAE, CX, and FX industrial heaters. While similar in function, always verify your model number against the factory parts list as Hot Dawg units often utilize different temperature trip points.
