Designed for the \u003cstrong\u003eAMH81205DNAA\u003c\/strong\u003e furnace, it monitors heat-exchanger and plenum temperature and shuts off the burners if the furnace overheats — protecting against blocked airflow, dirty filters, or blower failure. When a limit switch fails open or drifts out of spec, you'll see short-cycling, no-heat calls, or the furnace running the blower continuously.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: ~150°F (primary\/high limit)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed, auto-reset\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eFits: AMH81205DNAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eCategory: Safety controls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eGenuine OEM\u003c\/strong\u003e switch uses Goodman's exact temperature rating and mounting footprint, so it seats correctly and trips at the designed setpoint. Generic limits with the wrong trip temperature can cause nuisance shutdowns or, worse, fail to protect the heat exchanger.
