Mounted as a backup to the primary high limit, it provides an additional layer of overheat and flame-rollout protection, cutting the burner circuit if a fault develops. When this switch opens repeatedly, it typically signals a restricted-airflow or combustion problem that should be diagnosed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eColor code: Light Blue (auxiliary\/secondary limit)\u003c\/li\u003e\n\u003cli\u003eType: Snap-disc limit \/ rollout-style safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Backup overheat \u0026amp; rollout cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18090S4BXCC and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana compatible)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM option\u003c\/strong\u003e matches the factory trip temperature exactly, which is critical for a safety device.
