Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual-reset high-limit switch designed for the ACEC800805CXAB gas furnace and compatible Goodman/Amana models. This safety control monitors heat-exchanger and rollout temperatures and opens the circuit if the furnace overheats, shutting off the gas valve to prevent damage and hazardous conditions. As a manual-reset device, it must be pressed to reset after a trip — a deliberate design that forces inspection of the underlying cause (blocked airflow, failed blower, or flame rollout).

Specifications

Part number: 10123529
Type: Manual reset high-limit / rollout switch
Function: Normally closed, opens on overtemperature
Reset: Manual push-button
Fits: ACEC800805CXAB and compatible Goodman/Amana furnaces

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature specified for your furnace's heat exchanger. Generic switches may carry a different temperature rating; an incorrect trip point either nuisance-trips or, worse, fails to protect the unit. Because this is a safety control, we strongly recommend genuine OEM.

Installation

Difficulty: Easy. Two wire terminals and one or two mounting screws — about 15 minutes with power off. Important: a tripped limit switch is a symptom, not a cause. Diagnose and correct the airflow or combustion problem before returning the furnace to service.
