Mounted on the heat-exchanger bulkhead, this auto-reset thermal switch protects against overheating caused by restricted airflow — a dirty filter, blocked return, or failed blower. When supply-air temperature exceeds the setpoint, the switch opens and shuts off the gas valve, then automatically closes once the furnace cools.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162903 (OEM Goodman\/Amana)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 150°F (open on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type:\u003c\/strong\u003e Automatic (snap-disc)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally closed high-limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e VMES960603BNAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The 150°F trip point and disc mounting are specific to this furnace's heat-exchanger design. The OEM 20162903 guarantees the correct calibration; a generic snap-disc with a different setpoint can cause nuisance lockouts on cold days or fail to protect the heat exchanger. For a safety limit, OEM is the right call.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall Difficulty:\u003c\/strong\u003e Easy (2\/5). Cut power, photograph the wiring, remove two mounting screws, transfer the spade terminals, and reinstall. Clean or replace the air filter and confirm proper airflow, since restricted air is the most common cause of high-limit trips.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058207146355,"sku":"GOODMAN-13622","price":21.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-primary-limit-switch-for-vmes960603bnaa-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
