The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM high-limit safety control for the AMV80905CXBA gas furnace. This thermally activated switch monitors temperature within the furnace cabinet and opens the circuit to shut off the burners if the unit overheats — protecting the heat exchanger and blower from damage. As an auto-reset type, it re-closes once temperatures return to a safe range. A failed or nuisance-tripping limit switch commonly causes short cycling or a furnace that won't fire, and replacing it with the correct OEM control restores safe, reliable operation.

OEM vs. Generic

Limit switches are calibrated to a specific open/close temperature set point matched to the furnace design. Genuine Goodman 20269903 switches carry the correct trip rating, while generic substitutes may open at the wrong temperature — leading to nuisance trips or, worse, inadequate protection. For a safety-critical control, OEM is the right choice.

Installation Difficulty

Easy to Moderate (2/5). Disconnect power at the furnace, remove the two mounting screws, transfer the wire terminals, and secure the new switch. Confirm proper seating against the mounting surface for accurate sensing. Typically a 10–15 minute repair.
