As a secondary safety, the auxiliary limit adds a redundant high-temperature cutout — commonly guarding the blower compartment or a secondary airflow zone — so the burner de-energizes if temperatures exceed safe limits due to a blocked filter, failed blower, or restricted duct.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary (secondary) temperature limit switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (trip-temperature identifier)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VDS80603ANAA gas furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Redundant high-limit overheat protection\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause the auxiliary limit is a backstop safety device, matching the OEM trip temperature is essential. The genuine Goodman part is factory-calibrated to the VDS80603ANAA specification. Generic substitutes may trip at the wrong temperature, causing either nuisance shutdowns or, worse, failing to protect the furnace. Always confirm the light blue code before ordering.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — A straightforward two-screw, two-terminal swap.
