Modine 5H0749760001 Limit Switch

When you are troubleshooting a unit heater that is tripping on high limit, you need a precise Modine 5H0749760001 limit switch to restore safe operation. This OEM Modine 125-165F auto limit switch is a surface mount limit switch engineered specifically for technical reliability in harsh HVAC environments. Serving as the direct replacement for 5H74976-1, this component features an automatic reset function that interrupts the electrical circuit when the air temperature exceeds the 165°F threshold and closes again once it cools to 125°F.

Designed for industrial-grade durability, this high limit safety control is compatible with a wide range of Modine equipment, including DFG and DFP series duct furnaces and BV100 models. Its snap-disc design provides millisecond response times to prevent heat exchanger fatigue and potential fire hazards. For technicians managing commercial maintenance contracts, keeping this HVAC high temperature cutout in your service truck ensures you can resolve airflow or overheating issues on the first call without guesswork on limit switch compatibility.

• Precise Thermal Calibration: Operates on a fixed 125-165°F range for exact safety parameters.
• Universal Compatibility: Drops into DFG75 through DFG400 and DFP75 through DFP400 series units.
• Automatic Recovery: Eliminates manual resets, reducing nuisance service calls after minor temperature spikes.
• OEM Standards: Direct replacement prevents mounting issues or wiring mismatches common with generic parts.

Is the 5H0749760001 a manual or automatic reset?
This is an automatic reset limit switch. It will automatically re-engage the circuit once the sensed temperature drops to 125°F.

What causes this limit switch to trip frequently?
Typical causes include restricted airflow from dirty filters, a failing blower motor, or undersized ductwork that prevents proper heat dissipation across the exchanger.

Can I use this for the 5H74976-1 part number?
Yes, this is the official Modine 5H74976-1 replacement, maintaining the exact same technical specifications and mounting footprint.
