Mounted on the heat exchanger or blower deck, this safety control continuously monitors supply-air temperature and interrupts the burner circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing unsafe operation. A failed or nuisance-tripping limit is one of the most common causes of a furnace that lights briefly and then shuts down on high limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Primary limit \/ high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Automatic-reset thermal safety cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GCH950453BXAC and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Gas furnace heat\/limit safety circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eOEM (recommended):\u003c\/strong\u003e Exact factory trip temperature, mounting, and terminal layout — guaranteed drop-in fit and correct safety calibration. \u003cstrong\u003eGeneric:\u003c\/strong\u003e A lower-cost universal limit that may require verifying the trip point and adapting terminals; acceptable for budget repairs but not calibration-matched to the original.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy — 2 of 5.\u003c\/strong\u003e Typically two mounting screws and two spade connectors.
