This red manual-reset switch monitors heat-exchanger temperature and interrupts the burner circuit if the furnace overheats, protecting the unit from damage and preventing unsafe operation. Because it is a manual reset, it will not automatically re-close after a trip — a deliberate safety feature that forces the fault to be inspected before the furnace restarts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123535\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit switch (red button)\u003c\/li\u003e\n\u003cli\u003eFunction: Overtemperature burner cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90904CXAH and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM switch is calibrated to the exact trip temperature specified by Goodman engineering, ensuring the furnace's safety limits match the manufacturer's design. Generic aftermarket switches may differ in trip point, mounting footprint, or reset behavior, which can cause nuisance lockouts or, worse, delayed cutoff. For a critical safety control, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — requires disconnecting power at the breaker, removing the burner-compartment panel, transferring wiring to the new switch, and confirming correct placement. Homeowners comfortable with basic electrical work can manage it in about 20–30 minutes; otherwise a licensed HVAC technician is advised.
