Mounted on the heat exchanger, this normally-closed thermal switch continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger from cracking and preventing a potential fire hazard. A failed limit switch is a common cause of short cycling, no-heat calls, or a furnace that runs the blower but never fires.\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 (auto-reset)\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit safety switch, normally closed\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GCH950904CXAD\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat protection \/ burner cutout\u003c\/li\u003e\n\u003cli\u003eBrand: Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman switch is factory-calibrated to the exact 150°F trip point and mounting footprint your furnace's control board expects. Generic switches may carry a different setpoint or bracket geometry, leading to nuisance trips or, worse, failure to trip. For a life-safety component, we recommend genuine OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — Power off the furnace, disconnect the two spade terminals, remove two mounting screws, and install the replacement.
