The Goodman B1370108 Flame Rollout Switch is a genuine OEM 300°F manual-reset safety limit that protects the Goodman GUI150-5 gas furnace from dangerous flame rollout conditions. Mounted on the burner assembly, it trips and shuts off the gas valve if flames roll out of the heat exchanger — a common symptom of a cracked heat exchanger, blocked flue, or restricted combustion air. If your furnace locks out on a rollout fault, this switch must be replaced with the correct OEM part.

OEM vs. Generic

This is a safety-critical component — the OEM switch is calibrated to the exact 300°F trip point specified for this furnace. Generic switches with different trip temperatures or reset behavior can fail to protect the appliance or cause nuisance lockouts. Always use the OEM-rated part on combustion safety controls.

Installation Difficulty

Easy — a single-screw mount with two push-on terminals. Turn off gas and power first. If the switch keeps tripping after replacement, have the heat exchanger and venting inspected before returning the furnace to service.
