Goodman 20269903 Auxiliary Auto-Reset Limit Switch

The Goodman 20269903 is a genuine OEM auxiliary auto-reset limit switch for WGGE4360A090MAB gas furnaces. This secondary safety control guards a specific zone of the furnace — commonly the blower compartment or a secondary limit location — and opens the circuit if temperature climbs beyond its rated set point. Unlike a manual-reset device, this switch automatically re-closes once temperature returns to normal, allowing the furnace to resume operation without technician intervention while still shutting things down during a transient overheat.

Specifications

Part Type: Auxiliary auto-reset limit / safety switch
Function: Opens on over-temperature, self-resets on cool-down
Fits Model: WGGE4360A090MAB and related Goodman gas furnaces
Brand: Goodman (OEM)
Part Number: 20269903

OEM vs. Generic

The OEM 20269903 carries the exact trip and reset temperatures Goodman engineered for this furnace. A generic switch with the wrong calibration will nuisance-trip or, worse, fail to open when needed. The OEM part also matches the bracket and terminal layout, so it drops in without wiring changes — the right call for a safety-rated component.

Installation Difficulty

Rating: Easy. Cut power at the disconnect, remove the two mounting screws, transfer the spade terminals to the new switch, and reinstall. About 15 minutes with a nut driver. If the switch repeatedly trips, diagnose the airflow or heat-exchanger issue rather than replacing it blindly.
