The Goodman B1370154 Flame Rollout Switch is a genuine OEM safety control for the Goodman GMP100-3 gas furnace, rated to open at 350°F. The rollout switch is mounted near the burner assembly and instantly shuts off the gas valve if flames roll out of the burner box — a condition caused by blocked flue passages, a cracked heat exchanger, or poor combustion airflow. It is one of the most important safety devices in the furnace.

Trip Temperature: 350°F (opens on rise)

Category: Limit Switch (Safety Control)

OEM vs. Generic

Because a rollout switch protects against flame rollout and CO risk, the trip temperature and mounting must exactly match the furnace design. This OEM B1370154 is factory-set to 350°F with the correct bracket and terminals. Substituting a generic switch with a different setpoint can defeat the safety function. Always use OEM-rated rollout switches.

Installation Difficulty

Easy — mounts near the burner with screws and connects via spade terminals. However, a tripped rollout switch usually indicates an underlying problem (blocked flue or cracked exchanger); a licensed technician should diagnose the root cause before simply replacing or resetting the switch.

Shut off gas and power before servicing. If the switch trips again after replacement, stop and have the furnace inspected. Contact info@nationalhvacparts.com for fitment help.
