Goodman B1370108 Flame Rollout Switch (300°F)

The Goodman B1370108 is a genuine OEM flame rollout safety switch rated at 300°F for the GUPI075-4 gas furnace. Positioned near the burner assembly, it detects flame or heat rolling out of the burner box — a symptom of a blocked heat exchanger, clogged flue, or restricted combustion air — and immediately shuts off the gas valve to prevent fire and CO hazards. This is a critical, life-safety component.

Specifications

Trip temperature: 300°F
Reset type: Manual reset (button)
Configuration: Normally-closed safety limit
Terminals: 1/4" quick-connect spade
Fits: Goodman GUPI075-4 burner assembly

OEM vs. Generic

The OEM B1370108 is calibrated to the exact 300°F factory trip point and bracket for a guaranteed-correct safety response. A generic equivalent meets the same rating at a lower cost; for a safety switch, however, we strongly recommend OEM to ensure precise trip behavior.

Installation

Difficulty: Easy (DIY-friendly). One or two mounting screws and two spade terminals — typically a 5–10 minute replacement. Cut power at the disconnect before servicing.

Warning: If a rollout switch has tripped, do NOT simply reset and reuse the furnace. A tripped rollout indicates a serious combustion problem (cracked or blocked heat exchanger, plugged flue). Have the root cause diagnosed by a qualified technician before returning the unit to service.
