Mounted on the heat exchanger or blower housing, this normally-closed thermal switch opens the circuit if supply-air temperature exceeds its rated limit, shutting down the burners to prevent heat-exchanger damage and overheating. If your furnace short-cycles on high limit or fails to fire, a faulty limit switch is a common cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eType: Normally-closed primary high-limit switch, auto-reset\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GMH950704CXAB (and related Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eEquipment Type: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM Goodman limit switches are calibrated to the exact trip temperature specified for your furnace's heat exchanger. Generic switches may carry a similar temperature rating but differ in reset behavior, bracket geometry, and calibration accuracy — a mismatch on a safety control can lead to nuisance trips or unsafe operation. We recommend OEM for this critical component.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Usually a two-screw, two-wire swap taking under 20 minutes.
