This normally-closed thermal switch opens and cuts power to the gas valve if it senses excessive temperature — typically from a blocked filter, failed blower, or restricted airflow — protecting the heat exchanger from damage and preventing an unsafe condition. Unlike an auto-reset limit, it stays open until manually reset, alerting you to the underlying fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10123517\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit \/ thermal safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e WFD195070S4CAA (and related Goodman furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button reset\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e limit switch is calibrated to the exact trip temperature specified for your furnace. A generic switch with a different setpoint can trip too early (nuisance no-heat) or too late (bypassing critical overheat protection). Because this is a safety component, OEM specification matters — and it preserves your warranty.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2 of 5).\u003c\/strong\u003e Shut off power and gas, remove the mounting screws, transfer the wire terminals to the new switch, and remount.
