Typically mounted near the blower compartment, it provides backup over-temperature protection — opening the control circuit if temperatures climb from restricted airflow, such as a dirty filter or blocked return. It works alongside the primary limit to keep the furnace operating safely.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 120°F\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ secondary limit switch, normally closed\u003c\/li\u003e\n\u003cli\u003eFunction: Backup high-limit over-temperature protection\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370155\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eFits: GMPH080-5 and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman switch is calibrated to the 120°F auxiliary trip point and matches the mounting location and bracket your furnace uses.
