Goodman B1370145 300°F Flame Rollout Switch

The B1370145 is a genuine OEM manual-reset flame rollout switch engineered for the Goodman/Amana AMS81405DXAA gas furnace and compatible 80% AFUE models. Mounted on the burner assembly, this normally-closed safety limit opens at 300°F to shut down the gas valve if flame rolls out of the burner box — protecting your equipment and home from overheating and combustion hazards.

Specifications

Trip temperature: 300°F (open on rise)
Reset type: Manual push-button reset
Configuration: Normally closed (N.C.)
Function: Flame rollout / burner safety limit
Fits: Goodman & Amana 80% AFUE furnaces incl. AMS81405DXAA

OEM vs. Generic

Our OEM B1370145 matches factory trip tolerance and terminal spacing exactly, ensuring proper safety cutout timing. Generic aftermarket switches may drift on trip temperature and void furnace warranties. When it comes to a life-safety component, we recommend genuine OEM.

Installation Difficulty

Easy (1/5) — Two-wire spade connection and a single mounting screw. A repeatedly tripping switch usually signals a blocked flue, cracked heat exchanger, or bad burner alignment; diagnose the root cause before replacing. Always shut off power and gas before servicing.
