Typically mounted on the blower deck or near the cabinet, this control opens the circuit when blower-compartment temperatures climb too high — commonly due to a stuck blower or blocked return airflow — shutting down the burners to prevent overheating. It is a direct-fit replacement for the Goodman\/Amana \u003cstrong\u003eADV80703BXBB\u003c\/strong\u003e gas furnace. Replacing a worn or tripped auxiliary limit restores proper high-temperature protection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B1370155\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 120°F\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ secondary limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Blower-compartment overheat safety cutoff\u003c\/li\u003e\n\u003cli\u003eCompatible model: ADV80703BXBB furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM auxiliary limits are calibrated to the exact 120°F set point and use the correct mounting profile so the sensor reads cabinet temperature accurately.
