Mounted on the heat exchanger or burner box, the primary limit continuously monitors plenum temperature and opens the control circuit to shut down the burners if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard caused by restricted airflow, a dirty filter, or a failed blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety shutoff\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman ACVC960804CNBA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM limit control\u003c\/strong\u003e is calibrated to the exact trip temperature specified for the ACVC960804CNBA. Generic limits with different cut-out\/cut-in set points can cause premature shutdowns (short cycling) or, worse, fail to trip when needed. Because this is a primary safety device, matching the OEM temperature rating is critical.\u003c\/p\u003e\u003ch3\u003eOEM vs. Generic Comparison\u003c\/h3\u003e\u003cp\u003eOEM: factory-calibrated trip point, exact mounting footprint, full reliability. Generic: lower cost but variable calibration and fitment — not recommended for a safety limit.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eDisconnect power, remove the two mounting screws and the wire connectors, and install the new limit in the same orientation. A multimeter check of continuity confirms operation. Best performed by an HVAC technician.
