The Goodman B1370154 is a genuine OEM 350°F manual-reset rollout limit switch designed for the Goodman/Amana GMNTE100-4 gas furnace and compatible models. This safety control is mounted near the burner assembly and interrupts the ignition circuit if flame rollout is detected, protecting the heat exchanger and cabinet from dangerous overheating. A failed or tripped rollout switch is one of the most common causes of a furnace that ignites briefly and then shuts down on a lockout.
Our OEM Goodman B1370154 is calibrated to the exact 350°F trip point specified by the manufacturer, ensuring proper safety response and warranty compliance. Generic aftermarket rollout switches may vary in trip tolerance and mounting geometry, which can cause nuisance trips or improper safety cutout. For a critical safety component, we recommend the genuine OEM part.
Easy — Typically a two-wire quick-connect swap secured by a single bracket screw. Always shut off power and gas before servicing. If the switch continues to trip after replacement, inspect the heat exchanger and venting for a root-cause flame rollout condition.
