This normally-closed thermal safety control opens the ignition circuit if it senses excessive heat near the blower compartment, shutting the burners down before damage or a hazard can occur. A failed or nuisance-tripping auxiliary limit is a common cause of a furnace that starts, runs briefly, then stops on a safety lockout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip point: 120°F (auxiliary limit)\u003c\/li\u003e\n\u003cli\u003eType: Normally-closed automatic-reset thermal switch\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \/ Amana AMH80453ANAA furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370155\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\u003eOur \u003cstrong\u003eOEM\u003c\/strong\u003e option is the exact Goodman-specified switch with a factory-calibrated 120°F trip point and matching terminal geometry for a plug-and-play install. A \u003cstrong\u003eGeneric\u003c\/strong\u003e equivalent meets the same electrical rating at a lower price point but may require minor bracket adjustment. For a safety-critical limit control we recommend OEM to guarantee the correct calibration.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy (1 of 5)\u003c\/strong\u003e. Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch — typically a 10–15 minute job for a homeowner comfortable working inside the furnace cabinet. Always confirm power is off at the breaker before servicing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057601954163,"sku":"GOODMAN-5005","price":11.96,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-120-f-auxiliary-limit-switch-for-amh80453anaa-b1370155","provider":"National HVAC Parts","version":"1.0","type":"link"}
