This thermal safety control opens the furnace circuit if it senses excessive heat from a blocked filter, failed blower, or restricted airflow — protecting the heat exchanger from overheating and cracking. The manual-reset design requires a deliberate button press to restore the circuit, alerting the homeowner that a fault occurred rather than silently auto-cycling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e ACES800805CXAA furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens on over-temperature, protects heat exchanger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Limit switches are calibrated to a specific trip temperature matched to the furnace's heat-rise rating. The factory 10123529 opens at exactly the spec Goodman designed for this model. A generic switch with the wrong trip point can either nuisance-trip or, worse, fail to protect the heat exchanger. For a safety-critical control, always use OEM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty: Easy (2\/5).\u003c\/strong\u003e Shut off power and gas, disconnect the two wire leads, remove the mounting screws, and install the new switch in the same orientation. Allow 20–30 minutes. If the switch tripped, diagnose the airflow or combustion cause before resetting — a repeatedly tripping limit indicates an underlying problem.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057421664627,"sku":"GOODMAN-2228","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-aces800805cxaa-10123530","provider":"National HVAC Parts","version":"1.0","type":"link"}
