Nordyne 626343R Rollout Switch

The Nordyne 626343R Rollout Switch is a critical safety component designed for furnace flame rollout protection. This factory-authorized OEM replacement part is rated at 300°F and utilizes a Manual Reset SPST (Single Pole Single Throw) configuration. When combustion irregularities occur, such as a cracked heat exchanger or flue blockage, the switch detects excessive heat near the burner assembly and opens the circuit to shut down the heating cycle. Because this is a manual reset rollout switch, it requires a technician to physically inspect the heat exchanger and burner alignment before the system can be put back into service, ensuring that unsafe conditions are not bypassed.

The 626343R is the direct updated version for 626343 and 6263430, featuring a L300F temperature limit for high-sensitivity detection. Built for Nordyne furnace troubleshooting and repair, this normally closed disc switch is compatible with a wide range of brands including Intertherm, Miller, Frigidaire, and Gibson. It mounts securely near the combustion chamber and connects via standard 1/4-inch male quick-connect terminals, facilitating a direct swap-out during service calls. Utilizing genuine Nordyne replacement parts like the 626343R ensures that your HVAC system maintains its original factory safety specifications and prevents catastrophic equipment damage.
