This normally-closed thermal switch monitors temperature in the blower or burner compartment and opens the circuit if the furnace overheats, shutting down the gas valve to prevent heat-exchanger damage and fire hazards. The light-blue color code identifies its specific trip temperature—matching it exactly is critical for correct operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Type: Auxiliary \/ rollout limit switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMSS920403ANAA (Goodman\/Amana furnace)\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0130F00038\u003c\/strong\u003e is factory-calibrated to the precise trip and reset temperatures your furnace requires.
