The Goodman B1370154 is a genuine OEM flame rollout switch built for the Goodman GMPH080-5 gas furnace and compatible Goodman/Amana models. Mounted on the burner assembly, it shuts down the furnace if flames roll out of the combustion chamber — a critical safety response to blocked heat exchangers or venting problems. A tripped or failed rollout switch will stop the furnace from firing until reset or replaced.
The genuine Goodman rollout switch trips at the precise 350°F rating and mounts to the burner bracket exactly as designed. Because this control protects against flame rollout, using the correct OEM trip point is a safety priority — a mismatched generic could trip late. Always replace with the specified rating.
Easy — two screws and two spade terminals. Shut off power and gas before servicing. 15–20 minutes. If a rollout switch trips, have a licensed HVAC technician inspect the heat exchanger and venting before returning the unit to service.
