The auxiliary limit protects the blower compartment by opening the circuit when it senses excessive heat — typically caused by restricted return airflow, a dirty filter, or a blower fault. It works alongside the primary high limit to keep furnace temperatures within safe bounds.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Auxiliary high-limit switch (safety)\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 120°F\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370155\u003c\/li\u003e\n\u003cli\u003eFits model: AMH80453ANAC (80% gas furnace)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eFunction: Blower-compartment over-temperature protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370155 switch\u003c\/strong\u003e is set to the exact 120°F trip point specified for this furnace. Substituting a switch with a different rating can cause nuisance shutdowns or, worse, allow unsafe temperatures. As a safety control, it should always be replaced with the genuine factory part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Secured with two screws and spade terminals, the switch swaps out in minutes.
