This secondary safety control provides an additional layer of overheat protection — typically monitoring the blower compartment or a secondary zone — and interrupts furnace operation if temperatures climb beyond safe limits. It works alongside the primary high-limit to guard against restricted airflow, blower failure, or a blocked filter.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ Secondary Limit Switch\u003c\/li\u003e\n\u003cli\u003eColor: Light Blue (factory-coded set point)\u003c\/li\u003e\n\u003cli\u003eFunction: Secondary overheat safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMP100-42AA and related furnace models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe color coding on the \u003cstrong\u003eOEM Goodman 0130F00038\u003c\/strong\u003e corresponds to a specific trip temperature — installing the wrong set point can cause nuisance shutdowns or fail to protect the furnace.
