The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM safety component for the WGGE4348A115MAB gas furnace. This normally-closed thermal switch monitors temperature at a secondary location in the furnace and opens the circuit to shut down the burner if it detects an overheat condition — protecting the heat exchanger, wiring, and cabinet from heat damage. Because it is an auto-reset style, the switch closes again automatically once the furnace cools to a safe temperature.

Specifications

OEM Part Number: 20269903
Type: Auxiliary auto-reset thermal limit switch
Function: Overheat / high-limit safety cutout
Contacts: Normally closed (opens on overtemp)
Fits Model: WGGE4348A115MAB (and compatible Goodman/Amana furnaces)

OEM vs. Generic

Limit switches are calibrated to a specific trip temperature. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to trip and allow dangerous overheating. This genuine OEM Goodman limit switch is factory-calibrated for the exact cut-out temperature your furnace requires, ensuring reliable protection and a plug-in fit.

Installation Difficulty

Easy to Moderate. The switch mounts with screws and connects via push-on terminals. Cut power at the breaker before servicing. Photograph the wiring before disconnecting. Estimated time: 15–20 minutes. Gas furnace repairs involving safety circuits are best confirmed by a qualified technician.

Replace a failed or nuisance-tripping limit switch with the correct OEM part to restore safe, reliable furnace operation.
