This thermal cutout guards a specific zone — such as the blower deck or burner box — and opens the control circuit if that area exceeds its rated temperature, protecting against flame rollout or blower-compartment overheating. The color-coded housing denotes its factory trip point, so matching the exact part is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light blue (denotes trip temperature)\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\u003eFunction:\u003c\/strong\u003e Zone high-temperature \/ rollout protection cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana WFM18070S4BXCB gas furnace\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 switch\u003c\/strong\u003e is calibrated to the light-blue trip temperature specified for this furnace and matches the mounting footprint.
