Goodman B1370108 Flame Rollout Switch

The Goodman B1370108 is a genuine OEM flame rollout safety switch for the GUPI075-3 furnace. Mounted near the burner assembly, this manual-reset limit trips at approximately 300°F if flame rolls out of the burner box — a condition caused by a blocked heat exchanger, restricted venting, or a failing inducer. When tripped, it shuts off the gas valve to prevent fire and carbon-monoxide hazards.

Type: Manual-reset flame rollout switch
Trip Temperature: 300°F (open on rise)
Reset: Manual push-button

OEM vs. Generic

Rollout switches are life-safety devices calibrated to a precise trip point. A genuine Goodman B1370108 guarantees the correct temperature rating and bracket geometry. Repeated tripping usually signals an underlying combustion or venting problem — have the root cause diagnosed, not just the switch replaced.

Installation Difficulty

Easy (1 of 5). Two spade terminals and a single mounting screw or bracket clip. Shut off gas and power first. If the switch keeps tripping after replacement, stop and call a licensed technician immediately.
