Mounted on the heat exchanger \/ blower bulkhead, it continuously senses supply-air temperature and shuts off the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It is an \u003cstrong\u003eauto-reset\u003c\/strong\u003e control that re-closes once temperatures return to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary auto-reset high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety cutout for the gas valve circuit\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bulkhead flange with insertion probe\/disc\u003c\/li\u003e\n\u003cli\u003eTerminals: Spade connectors\u003c\/li\u003e\n\u003cli\u003eFits: AMH81005CXBD and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis control's cut-out and cut-in temperatures are matched to the AMH81005CXBD's heat-exchanger design. OEM 20162904 guarantees the correct set point and probe length. Generic limits with the wrong trip temp risk both nuisance shutdowns and unsafe over-temperature operation, which is why OEM is strongly recommended for this safety-critical part.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — Shut off gas and power, remove the mounting screws, withdraw the sensing probe from the airstream, transfer the wiring, and install the new control in the same orientation. Confirm airflow issues (filter, blower) are resolved so the new limit isn't tripped by the same underlying fault.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057641210227,"sku":"GOODMAN-5988","price":54.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-amh81005cxbd-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
