It backs up the primary limit by monitoring temperature at a specific point — such as the blower compartment or burner box — and interrupts the heating circuit if that zone exceeds its safe threshold. The blue color code indicates its factory trip temperature, so matching the exact part is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary \/ secondary limit switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (temperature-rating identifier)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens heating circuit on localized overtemperature\u003c\/li\u003e\n\u003cli\u003eFit: Goodman VMS80403ANAA and compatible models\u003c\/li\u003e\n\u003cli\u003ePart Number: 0130F00038 (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are color-coded to their trip point for a reason.
