The genuine OEM Goodman B1370154 flame rollout switch is a manual-reset safety limit rated to open at 350°F on your GSMS080-4 furnace. Mounted near the burner assembly, it detects flame rollout — flames escaping the heat exchanger due to blockage or a cracked exchanger — and immediately shuts the furnace down. This is a life-safety component; a tripped or failed rollout switch should always be investigated, not just replaced.

Specifications

Trip temperature: 350°F (open on rise)
Reset: Manual push-button reset
Function: Flame rollout safety limit
Fit: Goodman/Amana GSMS080-4 burner assembly
OEM Part Number: B1370154

OEM vs. Generic

The OEM Goodman B1370154 is set to the precise 350°F trip point and terminal layout your furnace expects. Because this is a combustion-safety device, an exact-rated replacement is strongly recommended — generic switches may offer a similar temperature rating for less, but any variance on a rollout limit is not worth the risk. Choose OEM here.

Installation Difficulty

Easy (2/5). Turn off power and gas, note the terminal wiring, unscrew the switch from its bracket, and mount the new one with the same orientation. About 10–15 minutes. IMPORTANT: if the old switch had tripped, diagnose the cause (blocked flue, dirty burners, cracked heat exchanger) before returning the furnace to service.
