Goodman B1370145 Rollout Limit Switch (300°F)

The Goodman B1370145 is a genuine OEM 300°F rollout limit switch engineered as a direct-fit replacement for the Goodman/Amana AMS80703ANA gas furnace. This manual-reset safety control mounts on the burner assembly and instantly cuts power to the gas valve if flame rollout is detected — protecting the heat exchanger, cabinet, and your home from overheating. A tripped rollout switch is one of the most common causes of a furnace that ignites and then shuts down.

Specifications

OEM Part Number: B1370145
Trip Temperature: 300°F (manual reset)
Type: Normally-closed rollout / flame safety switch
Fits Model: AMS80703ANA and compatible Goodman/Amana furnaces
Brand: Goodman (Amana compatible)

OEM vs. Generic

Our OEM Goodman option is the factory-exact part with the correct trip point and bracket geometry for a plug-and-play install. The Generic option is a quality-matched aftermarket switch with the same 300°F rating at a lower price point — ideal for budget repairs where an exact-fit alternative is acceptable.

Installation Difficulty

Easy (1/5). Two-wire spade connection and a single mounting screw. Always disconnect power before servicing and confirm no gas leak is causing the rollout before replacing the switch.
