This is a critical safety control: it opens the ignition circuit and shuts down the burners if it senses an overheat or flame-rollout condition, protecting the heat exchanger and the home. Unlike an auto-reset limit, the manual-reset button requires a technician to physically reset it after a trip — a deliberate design that flags an underlying problem.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual-reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123529\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003ePrimary fit: ACEC800804BXAA gas furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on overtemperature; requires manual reset button\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip temperature — do not substitute by appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause the trip temperature must match Goodman's factory specification, the \u003cstrong\u003eOEM 10123529\u003c\/strong\u003e is the only recommended replacement. A generic limit with the wrong setpoint can either nuisance-trip or, worse, fail to protect the heat exchanger.

Disconnect power and gas before servicing. Important: if a limit switch has tripped, diagnose the root cause (blocked airflow, dirty filter, failed blower) before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057162273139,"sku":"GOODMAN-10123529","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-acec800804bxaa-10123530","provider":"National HVAC Parts","version":"1.0","type":"link"}
