Mounted on the heat-exchanger partition, this snap-disc switch continuously monitors supply-air temperature and opens the control circuit if the plenum overheats — typically from restricted airflow, a dirty filter, or a failing blower. This protects the heat exchanger from thermal damage and cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit switch (snap-disc)\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (auto-reset on cool-down)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (NC)\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \/ Amana AMH951155DXAE and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162903\u003c\/strong\u003e guarantees the exact 150°F trip point, disc diameter, and mounting bracket for reliable protection.

Turn off power, note the two wire connections, remove the mounting screws, transfer the spade terminals, and remount the new switch. Around 10–15 minutes. Note that frequent limit tripping usually points to an airflow problem — check the filter and blower before assuming the switch itself has failed.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057681908083,"sku":"GOODMAN-6669","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150f-primary-limit-switch-for-amh951155dxae-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
