Mounted on the heat exchanger bulkhead, this safety switch continuously monitors supply-air temperature and opens the control circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing unsafe operation. When the temperature returns to a safe range, it automatically resets and allows normal heating to resume.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit \/ auto-reset temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat protection for heat exchanger\u003c\/li\u003e\n\u003cli\u003eReset: Automatic on temperature drop\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMEH801005CNAB and related Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 20162904 is calibrated to the exact trip temperature your furnace requires. Generic limit switches with the wrong set point can trip prematurely (short-cycling and no heat) or, worse, fail to trip when needed. For a life-safety component, matching the factory calibration is essential — we recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eReplacement typically involves removing two mounting screws and disconnecting the two spade terminals, then installing the new switch in the same orientation. No gas work is required. Always turn off power to the furnace at the disconnect or breaker before servicing. Verify the switch is seated flush against the metal it monitors for accurate readings.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057587208563,"sku":"GOODMAN-4516","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-high-limit-switch-for-ameh801005cnab-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
