Description
The Nordyne 626487R is an OEM replacement limit switch engineered to protect furnaces from overheating. Designed as a direct replacement for compatible Nordyne, Frigidaire, Gibson, Tappan, and other Nordyne-family heating systems, this high-limit safety control monitors heat exchanger temperatures and automatically shuts off the burner when temperatures exceed safe operating thresholds — then resets once temperatures return to normal.
How It Works
The limit switch continuously monitors the temperature within the furnace plenum or heat exchanger area. When temperatures rise above the upper limit set point, the switch opens the circuit to the gas valve or burner, shutting down heat production to prevent equipment damage, overheating, and potential fire hazards. Once the furnace cools to within the safe operating range, the switch resets automatically.
