The Goodman 10123529 Manual Reset Limit Switch is the genuine OEM overheat safety control for the AMES801005CXAA gas furnace. This normally-closed switch opens and shuts down the burners if it senses excessive temperature or flame rollout, protecting the heat exchanger and household from unsafe combustion conditions. Because it is a manual reset device, a trip signals an underlying issue (restricted airflow, blocked flue, or dirty burners) that should be corrected before pressing the reset button.

OEM vs. Generic

The OEM switch is factory-calibrated to the exact trip temperature specified for this furnace and uses the correct terminal and bracket geometry for a drop-in fit. Generic limit switches may trip at the wrong setpoint — nuisance-tripping or, worse, failing to protect the unit. For a safety-critical component, always use the genuine OEM control.

Installation Difficulty

Easy to Moderate — Disconnect power, unplug the two wire terminals, remove the mounting screws, and install the replacement. About 15–20 minutes. Because this protects against combustion hazards, have a technician diagnose the root cause of any trip before returning the furnace to service.
