Mounted on the heat-exchanger bulkhead, it continuously senses supply-air temperature and opens the gas-valve circuit if the furnace overheats — typically from low airflow, a dirty filter, a failed blower, or a blocked duct. This is a primary safety device that protects the heat exchanger from cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit \/ temperature safety control\u003c\/li\u003e\n\u003cli\u003eCircuit action: Opens on temperature rise (auto-reset)\u003c\/li\u003e\n\u003cli\u003eCalibration: Factory-set trip point for AMVC81155CXAA\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMVC81155CXAA and related AMVC furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip temperature and mounting footprint are model-specific. A generic limit with the wrong set point can allow the heat exchanger to overheat or cause repeated nuisance shutdowns. This genuine OEM control is calibrated to Goodman's specification for reliable, code-correct protection.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the burner\/control panel to access the bulkhead-mounted control, transferring the wiring, and reseating it in the correct orientation. Kill power and gas first. If the limit continues to trip after replacement, diagnose the airflow restriction rather than repeatedly resetting the furnace.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057875272051,"sku":"GOODMAN-20162904","price":59.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-amvc81155cxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
