This normally-closed thermal cutout monitors temperature in a secondary location (such as the blower or rollout area) and opens the circuit if it detects an overheat condition, shutting down the furnace to prevent damage. As an \u003cstrong\u003eauto-reset\u003c\/strong\u003e device, it re-closes automatically once temperatures return to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20269903\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary limit switch, auto-reset (SPST, normally closed)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ high-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman AMV80703BXA furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20269903 is calibrated to Goodman's exact open\/close trip temperatures for the AMV80703BXA. Because this is a safety component, an incorrectly rated generic switch can nuisance-trip or, worse, fail to trip at the correct temperature. Always use the OEM-spec part for safety-critical controls.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Moderate (2\/5).\u003c\/strong\u003e Requires disconnecting power, removing two spade wire terminals, and unscrewing the mounting bracket.
