Nordyne 626449R Auto Limit Switch Overview
The Nordyne 626449R is an automatic reset limit switch engineered to provide reliable high-temperature overheat protection in Nordyne-family furnaces and air handlers. With a 225–250°F operating range and a 3-1/8″ insertion depth, this switch is designed to interrupt the burner circuit when plenum or heat exchanger temperatures exceed safe thresholds — then automatically reset once temperatures return to normal operating levels. Using a genuine OEM replacement part ensures proper fit, function, and long-term reliability.
