This thermal safety control monitors temperature in the blower or secondary compartment and opens the circuit if it senses an overheat condition caused by restricted airflow, a dirty filter, a failed blower, or a blocked vent. When it trips or fails, the furnace shuts down heat as a protective measure. Because the switch is calibrated to a specific temperature and color-coded (light blue) to its trip point, using the exact OEM part is essential for correct, safe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ high-limit thermal safety switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eFits: GCH950905DXAB and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on overheat to protect the furnace and heat exchanger\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine 0130F00038 is factory-calibrated to the precise trip temperature Goodman engineered for this cabinet, indicated by its light-blue coding.
