This normally-closed thermal limit continuously monitors heat-exchanger and plenum temperature, cutting power to the gas valve if the furnace overheats — protecting your equipment and home from unsafe operating conditions. A tripping or open primary limit is one of the most common causes of a furnace that fires briefly then shuts down on a hard lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit safety cutout (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally-closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Goodman\/Amana VMES800804BXAA and compatible furnace platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Furnace limit switch \/ temperature control\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is the genuine Goodman-specified limit switch, calibrated to the exact trip temperature engineered for the VMES800804BXAA heat exchanger. Generic replacements often carry incorrect trip points or mounting geometry, which can cause nuisance lockouts or defeat the safety margin.
