Modine 5H0750020007 Rollout Switch

The Modine 5H0750020007 Rollout Switch is a critical safety component designed for commercial gas-fired unit heaters, engineered to detect flame rollout and prevent hazardous conditions. This specific manual reset rollout switch is rated for 300F and features an SPST (Single Pole Single Throw) configuration. Functioning as a direct OEM replacement part, this model replaces the legacy part number 5H75002-7. For technicians servicing Modine Hot Dawg or PDP series heaters, maintaining proper circuit continuity through the safety loop is essential. This high-temperature limit switch ensures that if the heat exchanger encounters downstream pressure issues or combustion air disruptions, the burner circuit is interrupted immediately. Utilizing genuine Modine HVAC parts ensures exact mounting alignment and calibrated trip points, preventing nuisance tripping while maintaining strict adherence to combustion safety protocols in demanding industrial environments.

Key Benefits

• Direct OEM Compatibility: Engineered as the precise replacement for Modine 5H75002-7, ensuring drop-in installation without field modifications.
• High-Temperature Calibration: Factory-set to 300 degrees Fahrenheit to provide accurate thermal protection for the burner compartment.
• Manual Reset Safety: The M/R SPST design requires a manual reset after a trip, forcing a technician inspection to identify the root cause of the rollout.
• Robust Build Quality: Built to withstand the thermal cycling typical of gas-fired unit heaters and duct furnaces.

Common Questions

Is the 5H0750020007 a direct replacement for my older Modine heater?
Yes, this unit is the current manufacturer-authorized replacement for the 5H75002-7 rollout switch used across several Modine product lines.

Can I bypass this switch if it keeps tripping?
No. A tripped 300F rollout switch indicates a serious combustion or venting issue. The manual reset feature is a safety requirement to ensure the heat exchanger and venting system are inspected by a professional.

What causes a roll-out switch to fail or trip?
Common causes include a cracked heat exchanger, soot buildup, or improper flue drafting which forces the flame out of the burner transition toward the switch.
