The Goodman B1370154 is a genuine OEM 350°F flame rollout limit switch for the GMPN120-5 gas furnace and related Goodman/Amana models. Mounted at the burner assembly, it senses flame rollout caused by a blocked heat exchanger or restricted venting and instantly shuts down the gas valve to prevent fire and heat damage.

Specifications

Trip temperature: 350°F
Reset: Manual reset button
Contact type: Normally Closed (opens on rise)
Function: Flame rollout / high-limit safety
Fits: Goodman GMPN120-5 furnace

OEM vs. Generic

Because this is a life-safety device, the calibrated 350°F trip point matters. This factory-original Goodman switch is matched to the burner geometry and airflow of the GMPN120-5. Generic switches with loose tolerances may trip early (nuisance no-heat) or, worse, trip late. Always replace a rollout switch with an exact OEM equivalent.

Installation Difficulty

Easy (2/5). Roughly a 10-minute swap: cut power and gas, remove the two mounting screws, transfer the wire leads to the new switch, and remount. If the original tripped, diagnose the underlying cause (dirty flame sensor, cracked heat exchanger, or blocked flue) before returning the furnace to service. Consult a licensed technician if unsure.
