Description
The Nordyne 626617 is a genuine OEM manual reset (M/R) limit switch engineered to protect furnace systems from dangerous overheating conditions. Designed with a 140–200°F operating range, this limit switch monitors heat exchanger temperatures and interrupts the burner circuit when temperatures exceed safe thresholds — preventing equipment damage and potential safety hazards.

Why Manual Reset?
Unlike automatic reset limit switches, a manual reset (M/R) limit switch requires a technician to physically reset the device after a trip event. This built-in safety measure ensures that the root cause of the overheating condition is identified and corrected before the system is returned to service — reducing the risk of repeated cycling, heat exchanger damage, or carbon monoxide hazards.
Application
- Compatible with select Nordyne-manufactured gas furnaces
- Ideal for residential and light commercial heating systems
- Recommended for use by qualified HVAC technicians
