The Goodman B1370145 Rollout Limit Switch is a genuine OEM manual-reset safety control for the Amana/Goodman AMS80905CXA 80% AFUE gas furnace and compatible models. Mounted on the burner bracket, this flame-rollout switch trips and cuts power to the gas valve if flames roll out of the heat exchanger — a dangerous condition usually caused by a cracked heat exchanger, blocked flue, or dirty burners. It is a critical last line of defense against combustion escaping the burner box.

Specifications

Trip temperature: 300°F
Type: Flame rollout safety switch (manual reset)
Configuration: Normally closed (opens on rollout heat)
Fits: Goodman/Amana AMS80905CXA and compatible 80% furnaces
OEM part number: B1370145

OEM vs. Generic

The OEM Goodman rollout switch is calibrated to trip at the precise 300°F rating and mounts flush to the factory bracket for accurate heat sensing. Because this is a life-safety control, we do not recommend generic substitutes — an incorrect trip point or poor bracket contact can prevent the switch from protecting against flame rollout. Always install genuine OEM.

Important Safety Note

A rollout switch that has tripped indicates an underlying combustion problem. Never simply reset or bypass it — have the heat exchanger, flue, and burners inspected by a licensed HVAC technician before returning the furnace to service.

Installation Difficulty: Easy

Rated Easy (2/5). About 15 minutes with basic hand tools. Disconnect power, remove the mounting screws, transfer the wire leads, and reinstall on the burner bracket.
