The Goodman B1370145 Flame Rollout Switch is a genuine OEM safety limit control designed for the AMS81405DNAA multi-position gas furnace and other compatible Goodman/Amana models. This manual-reset switch opens the ignition circuit if it detects a flame rollout condition — an unsafe situation where combustion escapes the heat exchanger — shutting the furnace down to protect your equipment and home.

Rated to trip at 300°F, this switch is a critical component of your furnace's layered safety system. If your furnace is locking out on ignition or shutting down mid-cycle, a tripped or failed rollout switch is a common cause.

Specifications

Trip Temperature: 300°F (manual reset)
Type: Flame rollout / high-limit safety switch
OEM Part Number: B1370145
Reset: Push-button manual reset
Compatibility: Goodman/Amana AMS81405DNAA and related 80% AFUE furnaces

OEM vs. Generic

Our OEM Goodman switch guarantees the exact trip temperature and mounting geometry your furnace was engineered for. Generic universal switches may vary in trip tolerance, risking nuisance trips or delayed protection. For a safety-critical component, factory-spec OEM is the right choice.

Installation Difficulty

Easy (1/5) — Two spade terminals and a single mounting screw. Always disconnect power before servicing. If the switch trips repeatedly after replacement, have a licensed HVAC technician inspect the heat exchanger and venting.
