The Goodman 10123529 is a genuine OEM manual reset high-limit switch for the AMEC800803BXAB gas furnace and compatible Goodman/Amana models.

OEM vs. Generic

This OEM limit switch is factory-calibrated to the exact trip temperature Goodman specifies for this furnace. Generic switches with incorrect set points can nuisance-trip on normal operation or, worse, fail to trip during a genuine overheat. On a life-safety component, OEM calibration is essential.

Installation Difficulty

Easy — A two-wire, two-screw replacement. Disconnect power, note wire positions, unscrew the old switch from the heat exchanger panel, and mount the new one. If the switch keeps tripping after replacement, diagnose airflow and heat exchanger issues before running.

A repeatedly tripping limit switch signals overheating — never bypass it. Install genuine Goodman 10123529 to restore reliable overheat protection and safe furnace operation.
