The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMH81005CNBB gas furnace and compatible Goodman/Amana models. This manual-reset limit acts as a safety cutout: if temperature at its mounting location exceeds the factory trip point — typically caused by flame rollout or a blocked/overheating condition — the switch opens, shutting off the gas valve to prevent damage or a hazard. Because it is manual reset, it must be physically reset with the button after the fault is corrected, alerting the technician that an abnormal event occurred.

Part number: 10123529
Type: Manual reset high-limit / rollout safety switch
Reset: Manual (push-button)
Action: Normally closed, opens on over-temperature
Fits: Goodman & Amana AMH81005CNBB and related furnaces

OEM vs. Generic: The genuine Goodman 10123529 is calibrated to the exact trip temperature specified for this furnace's combustion area and uses factory-matched terminal spacing and bracket geometry. Generic switches with the wrong trip point can nuisance-trip or, worse, fail to open when needed. This is a life-safety component — always use the OEM-specified part.

Install difficulty: Easy to Moderate (2/5). Shut off power and gas, note wire positions, unclip the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. Basic hand tools required. After installing, diagnose and correct the underlying cause (blocked flue, cracked heat exchanger, or airflow problem) before returning the furnace to service.
