This thermal safety control monitors temperature in the blower or burner area and opens the circuit if the furnace overheats — typically due to a dirty filter, blocked airflow, or blower failure — then automatically resets once temperatures return to normal. A failed limit switch can cause nuisance shutdowns, short cycling, or a furnace that will not fire at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20269903\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003eComponent: Auxiliary limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset type: Automatic (self-resetting)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on overtemperature, closes on cool-down\u003c\/li\u003e\n\u003cli\u003eFits: GMV80905CXBA furnace\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature.
