Goodman 20269903 Auxiliary Auto-Reset Limit Switch

The Goodman 20269903 is a genuine OEM auxiliary high-limit switch with automatic reset, used on Goodman/Amana AMV80704BXBA 80% variable-speed gas furnaces. This thermally-activated safety switch opens the control circuit if it senses excessive temperature — typically from restricted airflow, a dirty filter, or blower failure — shutting down the burners to prevent heat-exchanger damage. As an auto-reset device, it closes again once the sensed temperature returns to a safe range.

Specifications

Type: Auxiliary high-limit switch, auto-reset

Reset: Automatic (SPST, opens on temperature rise)

OEM vs. Generic

The OEM 20269903 is calibrated to the exact open/close trip temperature Goodman specifies for this furnace, so it protects the heat exchanger without nuisance tripping. Generic limits with the wrong setpoint either trip early (no heat) or too late (safety risk). For a safety switch, OEM is the correct choice.

Installation Difficulty

Easy (2 of 5). Disconnect power at the furnace, note or photograph the two wire positions, unscrew the mounting bracket, transfer the wires to the new switch, and remount. No calibration needed. If the switch keeps tripping after replacement, diagnose the underlying airflow problem.

Compatibility note: verify your model and part number before ordering. Fits Goodman and Amana equipment.
