The high-limit switch continuously monitors plenum and heat-exchanger temperature, interrupting the burner circuit if the furnace exceeds its safe operating range — commonly caused by a dirty filter, closed registers, or a failing blower. A faulty limit switch can cause short-cycling, no-heat calls, or nuisance shutdowns, making it a key diagnostic and replacement part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10728343\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High-limit temperature safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overtemperature burner cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e GMP100-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment Type:\u003c\/strong\u003e Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM\u003c\/strong\u003e Goodman limit switch is factory-calibrated to the exact trip and reset temperatures the GMP100-5 was designed around — the safest choice for a protective control.
