The Goodman 10123529 is a genuine OEM manual reset high-limit switch for the ACEC800603BXAB gas/electric package unit. This safety control opens the gas/heating circuit if the heat exchanger or supply air exceeds a safe temperature, protecting against overheating from blocked airflow or blower failure. Because it is a manual-reset device, it must be physically reset after a trip — a deliberate design that flags a fault condition for the technician to investigate.

Category: Limit Switch
Type: Manual reset high-limit / rollout safety switch
Compatible Model: ACEC800603BXAB

OEM vs. Generic

The OEM 10123529 is calibrated to the exact factory trip temperature and mounting footprint. Generic switches with a different setpoint can nuisance-trip or, worse, fail to protect the unit. For a safety-critical control, only the OEM-rated switch should be used.

Installation Difficulty: Easy

A direct-swap component: disconnect power, transfer the wiring, and mount the new switch in the same location. Typically 15–20 minutes. After installing, identify and correct the original overheat cause (dirty filter, failed blower, blocked ducts) before returning the unit to service.
