The Goodman B1370145 Rollout Limit Switch is a genuine OEM flame-rollout safety control engineered for the AMS80453ANA furnace and other compatible Goodman/Amana 80% AFUE gas models. Mounted on the burner assembly, this manual-reset switch opens the gas-valve safety circuit if flame rolls out of the burner box—protecting the heat exchanger and occupants from combustion hazards. A tripped rollout switch is one of the most common causes of a furnace that fires briefly and then shuts down on lockout.

Specifications

Trip temperature: 300°F (opens on rise)
Reset type: Manual push-button reset
Function: Flame rollout / burner safety limit
Terminals: 1/4" male quick-connect
Fits: Goodman/Amana AMS80453ANA and compatible 80% furnaces
OEM Part #: B1370145

OEM vs. Generic

The OEM Goodman B1370145 guarantees the exact 300°F trip point, terminal spacing, and mounting bracket for a true drop-in fit and full safety-listing compliance. Our quality generic equivalent matches the electrical and temperature spec at a lower price—ideal for out-of-warranty repairs where UL-matched OEM sourcing isn't required. Both are new, not refurbished.

Installation Difficulty

Easy (1/5). Shut off power and gas, unplug two spade terminals, remove the mounting screw, install the new switch, and reconnect. Typically a 10-minute repair with a nut driver. If the switch trips again after replacement, inspect for a cracked heat exchanger or blocked flue—the switch is doing its job.
