Mounted in the blower compartment, this secondary limit protects against heat buildup caused by a restricted blower, dirty filter, or blocked return — conditions the primary high limit may not catch. If cabinet temperature exceeds its 120°F set point, it opens the control circuit to shut the furnace down safely.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSet point \/ open temperature: 120°F\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary (secondary) limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Blower-compartment overheat safety\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370155\u003c\/li\u003e\n\u003cli\u003eCompatible model: Goodman GMPE125-5 furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact 120°F trip point and mounting footprint of the GMPE125-5. Generic replacements with different set points can cause premature shutdowns or fail to protect the blower housing.
