The Goodman B1370113 Auxiliary Limit Switch is a genuine OEM safety control rated to open at 120°F, built for the GMNT060-3 and compatible Goodman/Amana furnaces. This normally-closed thermal switch monitors temperature at a secondary location (such as the blower compartment or return-air area) and cuts power to the gas valve or burners if it senses an overheat or restricted-airflow condition — a critical safeguard against heat-exchanger stress and fire risk.

Type: Auxiliary / secondary high-limit switch, automatic reset

OEM vs. Generic

Safety limits must trip at the exact factory-specified temperature. Generic switches with loose tolerances may open too early (nuisance shutdowns) or too late (unsafe operation). The genuine B1370113 guarantees the correct 120°F setpoint and preserves your equipment's safety certification and warranty.

Installation

Difficulty: Moderate (30–45 min). Remove the failed switch, transfer the wiring, and mount in the identical location. Shut off power and gas before servicing. Because this is a safety device, verify proper cycling after install; when in doubt, use a licensed HVAC technician.

Protect your Goodman GMNT060-3 furnace with a genuine 120°F auxiliary limit switch.
