This normally-closed thermal switch monitors temperature at a secondary location in the furnace cabinet and opens the control circuit if it senses an overheat condition — typically caused by restricted airflow, a dirty filter, or a failing blower. When it trips, it de-energizes the gas valve to protect the heat exchanger from thermal damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WFM18070S4BXCC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary high-limit, normally-closed, auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Secondary overheat \/ airflow-failure protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe color coding on Goodman limit switches denotes a specific trip temperature — installing the wrong rating will either nuisance-trip during normal heating or fail to protect the furnace. The genuine 0130F00038 guarantees the correct light-blue trip point and mounting footprint. Generic switches rarely match Goodman's exact temperature stamp, making the OEM part the safe pick.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eA two-screw swap, about 10 minutes.
