The Goodman B1370108 Flame Rollout Switch is a genuine OEM 300°F manual-reset safety limit for Goodman GUPS050-2 gas furnaces. This switch protects against dangerous flame rollout — when combustion escapes the burner box due to a blocked heat exchanger, cracked flue, or bad draft. If it trips, your furnace shuts down the gas valve to prevent fire and CO hazards.

Specifications

Trip temperature: 300°F
Reset type: Manual (push-button)
Function: Flame rollout / high-limit safety cutout
OEM Part Number: B1370108
Fits: Goodman GUPS050-2 furnace
Brand: Goodman (OEM)

OEM vs. Generic

Because this is a life-safety component, the OEM Goodman switch is strongly preferred — it is calibrated to the exact 300°F trip point your furnace's control logic expects. Generic rollout switches vary in trip tolerance and terminal orientation; a mismatched trip point can nuisance-trip or, worse, fail to trip. Do not compromise on safety parts.

Installation Difficulty

Easy. Remove two mounting screws, unplug the two spade terminals, and swap in the new switch — 10–15 minutes with a nut driver. Shut off gas and power first. If the switch keeps tripping after replacement, stop and have a technician inspect the heat exchanger and venting.
