Nordyne 626350R Roll-Out Switch even at low pressure differentialsThe 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 detectedoften caused by a cracked heat exchanger, failed inducer motor, or blocked fluethe switch breaks the electrical circuit to
