Rated for a \u003cstrong\u003e150°F cutout\u003c\/strong\u003e, this normally-closed switch monitors heat-exchanger and plenum temperatures and shuts down the burners if the furnace overheats due to restricted airflow, a failed blower, or a dirty filter. It is a critical safety device — a tripped or failed limit is a common cause of a furnace that heats briefly then shuts off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary Limit Switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutout Temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMEH800805DNAB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis OEM limit switch is calibrated to the exact 150°F trip point specified for this furnace.
