Goodman 20269903 Auxiliary Limit Switch (Auto Reset)

The Goodman 20269903 is a genuine OEM auxiliary limit switch for the WGGE4330A045MAB gas furnace and compatible Goodman/Amana models. This secondary safety control works alongside the primary high limit, adding an extra layer of overheat protection — often positioned near the blower compartment to catch abnormal temperature buildup that the main limit might miss. If it detects excessive heat, it opens the circuit to shut down heating, then automatically resets once conditions normalize.

Specifications

Part Number: 20269903
Type: Auxiliary / secondary limit switch
Reset: Automatic (self-resetting)
Action: Opens on temperature rise (SPST)
Fits Model: WGGE4330A045MAB and compatible Goodman furnaces

OEM vs. Generic

This genuine Goodman OEM auxiliary switch is set to the exact trip temperature engineered for your furnace's blower and cabinet layout. Generic substitutes with the wrong setpoint can nuisance-trip and leave you without heat, or fail to trip when needed. As a redundant safety device, the OEM part keeps your furnace's protection system intact.

Installation Difficulty

Easy (1 of 5). Roughly 15 minutes: disconnect furnace power, unplug the two terminals, remove the mounting screws, and install the replacement in the same location and orientation. If the switch had been tripping, verify blower operation and airflow before restoring power. When in doubt, use a licensed HVAC professional.
