The Goodman B1370108 Flame Rollout Switch is a genuine OEM manual-reset safety limit rated at 300°F, used on the GUS125-5 gas furnace and compatible Goodman & Amana models. This switch shuts off the burners if flames roll out of the burner box due to a blocked heat exchanger, cracked exchanger, or poor venting — protecting your home from overheating and combustion hazards. A tripped or failed rollout switch is often a symptom of an underlying airflow or venting problem that should be inspected.

Specifications

Trip temperature: 300°F
Type: Manual-reset (button) flame rollout limit
OEM Part Number: B1370108
Fits: Goodman GUS125-5 and select Goodman/Amana furnaces
Function: Combustion / rollout safety cutoff

OEM vs. Generic

Because this is a life-safety component, the OEM B1370108 is strongly recommended — it carries the exact trip point and reset behavior the furnace was certified with. Generic switches may have differing temperature tolerances; using the correct rating is essential for safe operation.

Install Difficulty

Easy. Typically two spade-terminal wires and one or two mounting screws. About 15–20 minutes. Always shut off gas and electric power first. If the switch keeps tripping after replacement, stop and have the heat exchanger and venting inspected by a licensed technician.
