Nordyne 626422R Limit Switch the Carrier 2-03208 OEM partThe Nordyne 626422R Limit Switch is a critical safety component designed for furnace rollout protection in gas fired and oil fired HVAC systems. This thermal limit switch is engineered to open the circuit at a 155F cut out temperature, immediately interrupting the gas valve circuit if flame rollout or excessive heat is detected near the burner box. As a manual reset rollout switch, it requires a technician to physically inspect the heat exchanger and
