This limit control continuously monitors heat-exchanger temperature and opens the burner\/gas-valve circuit if the furnace overheats — protecting the heat exchanger and blower from thermal damage. A failed or drifting limit is a common cause of short-cycling, no-heat, and repeated lockout faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset thermal switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VMS80604BXAA gas furnace\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE furnace safety circuit\u003c\/li\u003e\n\u003cli\u003eMounting: Bolt-on to furnace vestibule\/heat-exchanger panel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is factory-calibrated to the exact trip temperature Goodman specifies for this cabinet, guaranteeing correct safety-circuit behavior and preserving your warranty.
