The Goodman 20269903 is a genuine OEM auxiliary auto-reset limit switch for the Goodman GMV80703BXA furnace and compatible models. This high-temperature safety control monitors heat in the blower or supply area and interrupts the burner circuit if temperatures exceed the safe threshold — protecting the heat exchanger and cabinet. Being auto-reset, it restores the circuit automatically once temperatures return to normal, unlike manual-reset rollout switches.

OEM vs. Generic

The OEM limit switch is calibrated to the exact trip temperature Goodman specifies for this furnace, ensuring it protects without nuisance-tripping. Generic switches with approximate temperature ratings can trip early (short cycling) or too late (safety risk). For a safety control, the correctly rated OEM part is the only recommended choice.

Installation Difficulty

Easy (2/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. Basic hand tools only. Never bypass a limit switch. Shut off gas and electrical power before servicing.
