Goodman B1370154 Flame Rollout Limit Switch (350°F)

The Goodman B1370154 is a genuine OEM flame rollout limit switch built for the GMPH075-4 gas furnace and related Goodman/Amana models. Mounted on the burner assembly, it is a critical safety device that detects flame rollout — flames escaping the heat exchanger — and immediately cuts power to the gas valve to prevent fire and overheating. This switch opens at 350°F.

Specifications

Trip temperature: 350°F
Type: Flame rollout limit switch (manual reset)
Function: High-temperature burner safety cutout
Equipment: Gas furnace
Fits: Goodman GMPH075-4 and select GMP/GMPH series
OEM Part Number: B1370154

OEM vs. Generic

The OEM Goodman switch is factory-calibrated to the precise 350°F trip point and drops into the original bracket without modification. The Generic equivalent matches the same temperature rating and terminal layout at a lower cost — a solid choice for routine safety-component replacement. Both fully restore rollout protection.

Installation Difficulty

Easy (1/5). Most replacements take under 15 minutes. Shut off power and gas, unplug the two spade terminals, remove the mounting screw(s), and install the new switch in the same orientation. Never bypass a tripped rollout switch — if it keeps opening, a technician should diagnose the underlying combustion or heat-exchanger issue.
