Mounted on the heat exchanger, it monitors plenum temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger and preventing fire hazards. A failed limit causes short-cycling, no-heat conditions, or a furnace that runs the blower continuously.\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\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFits: AMEH801005CXAA and compatible Amana\/Goodman furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is calibrated to the precise trip and reset temperatures Goodman engineered for this furnace.
