The Goodman B1370108 Flame Rollout Switch is a genuine OEM manual-reset safety limit that protects the Goodman GUPS100-3 gas furnace from flame rollout. If burner flames roll out of the combustion chamber — typically from a blocked heat exchanger, cracked flue, or restricted venting — this 300°F switch trips and shuts off the gas valve to prevent overheating and fire.

Specifications

OEM Part Number: B1370108
Trip Temperature: 300°F (open on rise)
Reset Type: Manual push-button reset
Terminals: 1/4 in. male spade
Fits: Goodman GUPS100-3 furnace

OEM vs. Generic

As a life-safety control, this OEM Goodman switch is calibrated to the exact 300°F trip point specified for the GUPS100-3. Generic switches with loose temperature tolerances can nuisance-trip or, worse, fail to trip on time. On a safety device, always fit OEM.

Installation Difficulty

Easy — unplug the two spade connectors, remove one or two mounting screws, and swap in the new switch. Under 15 minutes. Note: if a rollout switch has tripped, diagnose and correct the root cause (heat exchanger / venting) before returning the furnace to service.
