This secondary safety control works alongside the primary high limit, adding an extra layer of overheat protection — often positioned near the blower compartment to catch abnormal temperature buildup that the main limit might miss. If it detects excessive heat, it opens the circuit to shut down heating, then automatically resets once conditions normalize.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20269903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ secondary limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Opens on temperature rise (SPST)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WGGE4330A045MAB and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e auxiliary switch is set to the exact trip temperature engineered for your furnace's blower and cabinet layout.
