Nordyne 626350R Roll-Out Switch

The Nordyne 626350R Roll-Out Switch is a critical SPST safety component designed for gas furnace flame rollout protection. Engineered to open at a fixed temperature of 260F, this manual reset limit switch serves as a primary safeguard against combustion gases escaping the heat exchanger. When a flame rollout condition is detectedùoften caused by a cracked heat exchanger, failed inducer motor, or blocked flueùthe switch breaks the electrical circuit to the gas valve, forcing an immediate system shutdown. This OEM part is a direct replacement for Nordyne 626350 and cross-references with the Therm-O-Disc 36TX16-6251. It is essential for maintaining the safety of Nordyne, Intertherm, and Miller heating units, ensuring the burner assembly operates within specified thermal parameters. For technicians troubleshooting furnace short cycling or safety lockouts, verifying the continuity of this L260 rollout switch is a standard diagnostic step to prevent hazardous backdrafting and cabinet scorching.

• Critical Safety Protection: High-precision thermal sensing triggers at 260 degrees Fahrenheit to mitigate fire hazards and carbon monoxide risks.
• Manual Reset Functionality: Requires a physical reset by the technician, ensuring the underlying combustion issue is addressed before the system resumes operation.
• Broad OEM Compatibility: Verified for use across Nordyne, Miller, Intertherm, and Frigidare furnace models.
• Durable Construction: Built to withstand the high-ambient environments near the furnace burner box for long-term reliability.

What causes a roll-out switch to trip?
A trip is typically caused by restricted airflow, such as a blocked exhaust vent, a failing draft inducer motor, or internal structural damage like a clogged secondary heat exchanger.

Can I bypass the 626350R for testing?
Never bypass a safety limit. If the switch has 'popped,' it indicates a dangerous flame rollout condition that must be repaired by a professional to ensure the unit is venting correctly.

Is the 626350R compatible with my furnace?
This 260F manual reset switch is standard on many Nordyne-manufactured gas furnaces. Always check your specific furnace wiring diagram and parts list to confirm the required temperature rating and reset type.
