The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM safety control for the GMV80704BXA variable-speed gas furnace. This thermal limit switch monitors temperature in the blower or burner compartment and opens the circuit if the furnace overheats, shutting down the burners to prevent heat-exchanger damage or fire. Because it is an auto-reset design, it re-closes automatically once temperatures return to a safe range — no manual reset required. A tripping or failed limit switch is a common cause of short-cycling and no-heat calls.

Part Number: 20269903
Type: Auxiliary high-limit switch, auto-reset
Reset: Automatic (SPST, opens on temperature rise)
Fits: Goodman GMV80704BXA and compatible GMV80 series furnaces
Function: Overheat safety shutoff

OEM vs. Generic

The genuine Goodman OEM switch is factory-calibrated to the precise trip temperature specified for this furnace. Generic universal limits may open at the wrong setpoint, causing either nuisance trips or a failure to protect the heat exchanger. OEM ensures correct calibration and terminal fit.

Installation Difficulty

Moderate (2/5). Requires removing two mounting screws and transferring two wire connectors. Shut off gas and 120V power at the disconnect before servicing. Basic multimeter skills recommended to confirm the old switch is faulty.
