Mounted on the heat exchanger or burner bulkhead, this auto-reset control continuously senses supply-air temperature and shuts down the burners if the furnace overheats — typically from a dirty filter, blocked ductwork, or a failed blower.\u003c\/p\u003e\u003cp\u003eThe primary limit is one of the furnace's most important safety devices. A control that has drifted out of calibration or failed open causes short cycling, no-heat conditions, or a burner that fires but never runs a full heating cycle. Installing the correct OEM-calibrated limit restores reliable, safe operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on temperature rise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature shutdown of burners \/ gas valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensing:\u003c\/strong\u003e Supply-air \/ heat exchanger temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Amana AMEC960402BNAC and select Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The trip and reset temperatures on this limit are matched to the furnace's heat-exchanger design.
