Modine 5H0730570001 Switch

The Modine 5H0730570001 Switch is a critical safety component designed for blocked vent detection in gas-fired unit heaters. Operating with a precise 240F temperature rating, this limit switch functions as a spill switch, monitoring the draft diverter or draft hood for flue gas spillage. As a veteran-grade OEM replacement part, this component ensures the safety circuit remains intact under normal operating conditions and triggers a system shutdown if ventilation is obstructed. The 5H0730570001 is the direct engineering replacement for the Modine 5H73057-1, maintaining exact electrical specifications and mounting footprint for seamless field integration.

This manual reset limit switch is built for high-demand commercial HVAC applications and is compatible with a wide range of Modine series, including PD75, PD100, PD125, PD200, BD75, BD100, BD125, and BD200 heaters. It also fits PAE, BAE, and DHE models, providing a versatile solution for furnace troubleshooting and vent safety switch repair. By sensing excess heat at the vent assembly, it prevents hazardous combustion byproduct recirculation, protecting both the equipment and the facility. For contractors performing preventative maintenance, verifying the L240F rating and replacing worn safety controls with genuine Modine heating parts is essential for system reliability and code compliance.

• Direct OEM Compatibility: Verified replacement for 5H73057-1, ensuring no modifications are needed during installation.
• High-Temperature Precision: 240-degree Fahrenheit trip point provides accurate protection against vent blockages and flue gas spillage.
• Enhanced System Safety: Critical fail-safe that cuts power to the gas valve when venting failures are detected.
• Broad Application Range: Fits numerous Modine unit heaters, including PD, BD, PAE, and BAE series models.
• Durable Construction: Engineered to withstand the thermal cycling typical of industrial and commercial heating environments.

• Is this an auto-reset or manual reset switch? This is a manual reset safety switch, requiring a physical button press once the venting issue has been cleared.
• Will this fix a three-flash error code on my Modine board? Yes, a three-flash code typically indicates an open safety circuit; if the 5H0730570001 is tripped or faulty, replacement will restore the circuit.
• Can I use this for other brands? While designed specifically for Modine equipment, it may fit other units requiring a 240F L-series limit; however, we recommend using it only for specified Modine models to ensure safety.
