Goodman 20269903 Auxiliary Auto-Reset Limit Switch

The Goodman 20269903 is a genuine OEM auxiliary auto-reset limit switch for the WGGE4348A090MAB gas furnace and compatible models. Mounted near the blower or secondary heat area, it opens the control circuit on an overtemperature event and automatically closes again once temperatures return to normal — protecting the furnace during transient conditions like a temporarily restricted filter or brief blower interruption without requiring a manual reset.

Specifications

Type: Auxiliary auto-reset thermal limit switch
Action: Opens on overtemperature, auto-recloses on cooldown
Function: Secondary overheat / blower-area protection
Reset: Automatic (self-resetting)
Fits: Goodman WGGE4348A090MAB and related furnaces

OEM vs. Generic

The OEM Goodman switch is calibrated to the factory trip and reset temperatures for this cabinet. Generic substitutes with different setpoints cause nuisance shutdowns or leave the furnace under-protected. For a safety limit, match OEM specs exactly.

Installation Difficulty

Easy (1/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same position and orientation. Roughly 10–15 minutes with basic tools. If the switch was tripping, check the filter, blower, and airflow before returning the unit to service.
