The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch engineered for the GMH950904CXAA 96% AFUE two-stage furnace and compatible Goodman/Amana models. Mounted on the heat exchanger vestibule, this limit acts as a critical safety device: it opens the gas valve circuit and shuts down the burners if the plenum temperature exceeds a safe threshold, protecting the heat exchanger and your home from overheating.
OEM vs. Generic: This is the factory OEM control with the exact trip temperature and mounting bracket your furnace was designed around. Generic snap-disc limits often differ in calibration and bracket geometry, which can cause nuisance lockouts or improper safety response. For a safety-critical component, we strongly recommend the OEM part.
Install difficulty: Easy (1 of 5). Disconnect power, remove the two mounting screws and the two spade wire connectors, swap in the new limit, and reconnect. A qualified HVAC technician should verify operation after replacement. Typical job time is under 15 minutes.
