Mounted on the heat exchanger bulkhead, the primary limit continuously monitors supply-air temperature and opens the 24V control circuit if the furnace overheats — typically from low airflow, a clogged filter, or a failing blower. It automatically resets once temperature returns to a safe range, protecting the heat exchanger from thermal stress.\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\u003eAction: Opens on temperature rise, closes on cool-down\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed, 24V control interrupt\u003c\/li\u003e\n\u003cli\u003eMounting: Factory bulkhead hole pattern and bracket\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMVC800804CXAB furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit's trip point is matched to this furnace's cabinet and heat-exchanger design.
