Nordyne 626375R Rollout Switch

The Nordyne 626375R is a critical manual reset rollout switch designed for Nortek, Intertherm, and Miller gas-fired furnaces and packaged units. Engineered to trip at a 210°F temperature limit (L210), this safety component monitors the burner vestibule for flame rollout conditions. When excessive heat is detected outside the combustion chamber—often caused by a cracked heat exchanger, clogged vent piping, or inducer motor failure—the switch opens the 24V safety circuit to immediately terminate the heating cycle and prevent equipment damage or hazardous conditions.

As a genuine OEM replacement part, the 626375R features a 1/2-inch OD footprint with standard spade terminals for seamless integration into existing furnace wire harnesses. This limit switch is compatible with a wide array of brands under the Nortek umbrella, including Frigidaire, Maytag, Gibson, and Tappan. For contractors performing furnace troubleshooting, this switch is the direct solution for units throwing a limit circuit lockout code where the rollout has physically tripped. Professional inspection of the heat exchanger and combustion air pressure is recommended before resetting or replacing this component.

• Ensures combustion safety by detecting flames exiting the heat exchanger transition.
• Manual reset button prevents the system from automatically restarting under unsafe conditions.
• Precision 210F thermal response provides accurate protection for high-efficiency gas furnaces.
• Universal compatibility across Nordyne and Nortek Global HVAC brands like Miller and Intertherm.
• Robust OEM construction maintains circuit integrity within packaged HVAC units and mobile home furnaces.

• Is the 626375R compatible with my furnace model? This switch fits most Nordyne, Intertherm, and Miller furnaces requiring a 210-degree manual reset rollout. Cross-reference your model number to confirm.
• Why does my rollout switch keep tripping? Frequent tripping usually indicates backdrafting, sooted heat exchangers, or restricted flue venting rather than a faulty switch.
• How do I test a 626375R rollout switch? Use a multimeter to check for electrical continuity; if the reset button is depressed and there is no continuity, the internal bimetal disc is likely failed.
