Auxiliary limit switches provide a secondary layer of overheat protection—typically mounted near the blower or a secondary airflow path—so the furnace shuts down safely if the primary limit fails to catch an overheat condition. A failed auxiliary limit can cause intermittent no-heat calls or safety lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ secondary limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GDH80403ANBA and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Secondary furnace overheat protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause the auxiliary limit is calibrated to a specific trip temperature and bracket location, the factory \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e part is strongly preferred.

Kill power at the breaker first, transfer the two spade connectors one at a time to avoid a wiring mix-up, and confirm the switch seats flush against its mounting surface.
