The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light-blue housing) is a genuine OEM safety control for the Amana/Goodman AMVM961155DXAA modulating gas furnace. This thermally activated switch monitors furnace temperature and opens the circuit if it detects an overheat or heat-rollout condition, shutting down the burners to prevent damage and hazards. A tripped or failed auxiliary limit is a frequent cause of no-heat and repeated lockout faults.
Limit switches are calibrated to a specific trip temperature — the light-blue code identifies this exact rating. Using the genuine OEM part guarantees the correct cutoff point; a mismatched generic switch can trip early (nuisance no-heat) or, worse, too late (a real safety risk). Always match the OEM color and part number.
Easy — Disconnect furnace power, remove the two mounting screws, transfer the wire terminals, and secure the new switch. A low-cost, high-value safety replacement.
