The primary limit continuously senses supply-air temperature and de-energizes the gas valve if the heat exchanger exceeds its safe operating range — commonly triggered by a dirty filter, blower fault, or restricted ductwork. A drifting or failed limit control leads to intermittent no-heat calls and short cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air over-temperature protection\u003c\/li\u003e\n\u003cli\u003eSensing: Factory-calibrated trip set point\u003c\/li\u003e\n\u003cli\u003eMount: Vestibule \/ heat-exchanger bracket (match original)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Amana\/Goodman AMEC800805DXAB furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAs a primary safety device, the \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e control carries the exact temperature calibration and probe length your furnace requires.
