The Goodman B1370108 Flame Rollout Switch is a genuine OEM 300°F manual-reset safety limit for the GUS050-2 gas furnace. Mounted on the burner box, this switch trips and cuts power to the gas valve if flames roll out of the burner compartment — a critical safety response to a cracked heat exchanger, blocked flue, or restricted combustion air. If your furnace lights then shuts down and the switch won't reset, it is protecting your home from a dangerous condition.

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the exact 300°F trip point specified for this furnace. Because this is a life-safety component, using a switch with a different temperature rating or reset type is strongly discouraged. The OEM part guarantees the correct trip threshold and factory reliability.

Installation Difficulty

Rating: Easy (2/5). Usually 15–20 minutes: shut off power and gas, remove one or two mounting screws, transfer the wires, and secure the new switch. Important: a tripped rollout switch signals an underlying problem — inspect the heat exchanger and venting before returning the furnace to service.
