The auxiliary limit provides backup over-temperature protection — commonly mounted near the blower or rollout area — and shuts off the burners if heat builds up where the primary limit can't sense it. Its light-blue color code marks a distinct factory trip-temperature from the primary (pink) limit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary high-limit thermal switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light blue (factory-set trip point)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e ACES800804BXAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Secondary over-temperature cutout, auto-reset\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The light-blue auxiliary limit is calibrated to a specific setpoint that differs from the primary limit — they are not interchangeable.
