This color-coded (light blue) thermal safety switch protects the furnace from overheating by interrupting power to the gas valve and control circuit if temperatures exceed its factory-set trip point. It is a normally-closed, temperature-activated cutout that automatically resets once the assembly cools.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eCompatible Model: DMP125-52AA\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary (rollout\/high) limit switch, snap-disc\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue\u003c\/li\u003e\n\u003cli\u003eAction: Normally-closed, auto-reset thermal cutout\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ secondary limit protection\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause a limit switch is a \u003cstrong\u003esafety device\u003c\/strong\u003e, the trip temperature matters. The genuine OEM 0130F00038 is calibrated to the exact set point the furnace was engineered for. Generic snap-disc switches may look identical but carry different trip temperatures — installing the wrong rating can either nuisance-trip or, worse, fail to protect the heat exchanger. Always match the OEM color code and part number.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Usually two mounting screws and two push-on spade terminals. Shut off power and gas before servicing, and confirm the replacement carries the same light-blue calibration. Repeated tripping after replacement points to an airflow problem (dirty filter, blocked coil, or failing blower) that should be corrected.\u003c\/p\u003e\u003cp\u003eCovered by our DMP125-52AA fitment guarantee.
