This auto-reset thermal safety control monitors temperature at the blower or supply area and opens the circuit if it climbs beyond the rated cutoff, shutting the furnace down to prevent heat-exchanger damage or a fire hazard. When the temperature returns to normal, the switch automatically resets and restores operation — no manual button push required.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary high-limit, auto-reset (SPST, opens on rise)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20269903\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMV81155CXBB gas furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ rollout safety limit\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman limit switches are factory-calibrated to the exact trip temperature the AMV81155CXBB requires.
