Nordyne-Intertherm 626458R Limit Switch 190°F-140°F OEM

Nordyne / Intertherm / Miller 626458R Limit Switch | 190°F - 140°F OEM

The Nordyne 626458R is a genuine factory-authorized double-pole limit switch designed for use in residential electric furnaces and air handlers. As an Original Equipment Manufacturer (OEM) safety component, its primary function is to monitor the internal temperature of the heating cabinet and interrupt power to the heating elements if temperatures exceed safe operating limits.

This switch features a 190°F - 140°F rating, meaning it will trip (open the circuit) if the temperature reaches 190°F and will automatically reset (close the circuit) once the temperature cools back down to 140°F.

Compatibility & Cross-Reference

The 626458R is the current production standard for various Nordyne brands, including Intertherm, Miller, and Broan:

  • Directly Replaces P/Ns: 626458 and 64TX11.
  • Model Series: Frequently found in E1, E2, and E3 series electric furnaces.
  • Double-Pole Design: This configuration allows the switch to break both "legs" of the power supply to the heating elements for enhanced safety in high-wattage electric heat applications.

Why Choose a Genuine Nordyne OEM Limit Switch?

  • Precision Temperature Calibration: Unlike universal aftermarket switches, this OEM part is calibrated to the exact thermal profile of the Nordyne heat exchanger, preventing nuisance trips while ensuring absolute safety.
  • Ceramic Construction: Built with a high-temperature ceramic body designed to withstand the intense radiant heat of electric elements without cracking or warping over time.
  • Direct Fit: Engineered with the correct mounting flange and terminal spacing for the original factory wiring harness, ensuring a secure and reliable electrical connection.
