This automatic high-limit switch monitors supply-air temperature in the heat exchanger area and opens the burner circuit if the furnace overheats — typically from restricted airflow such as a dirty filter, blocked ducts, or a failed blower. It automatically resets once temperatures return to a safe range. As the furnace's front-line thermal protection, a correctly rated primary limit is essential for safe, code-compliant operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed (opens on over-temperature)\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003eFit: Goodman WFD195070S3BAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eReset: Automatic on cool-down\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e limit is calibrated to the precise trip temperature and insertion depth specified for your heat exchanger.
