The Goodman B1370145 Rollout Limit Switch is a genuine OEM flame-rollout safety control designed for the AMV80905CXBB gas furnace and other compatible Goodman and Amana models. This normally-closed switch monitors the burner compartment for flame rollout and opens the ignition circuit if temperatures exceed its 300°F trip point, shutting the furnace down to prevent a dangerous overheat condition.

Specifications

Trip temperature: 300°F (open on rise)
Type: Manual-reset flame rollout safety switch
Configuration: Normally closed (SPST)
Fits: Goodman / Amana AMV80905CXBB and compatible gas furnaces
OEM part number: B1370145

OEM vs. Generic

The OEM Goodman switch is calibrated to the exact factory trip point and mounting footprint, ensuring correct safety response and a bolt-in fit. Generic aftermarket rollout switches may vary in trip tolerance and terminal orientation, which can cause nuisance tripping or improper safety operation. For a life-safety component we recommend the OEM part.

Installation Difficulty: Easy

A two-wire swap with a nut driver — typically 10–15 minutes. Always disconnect power before servicing. If the switch has tripped, diagnose and correct the underlying rollout cause (blocked heat exchanger, poor venting, or dirty burners) before restarting.
