Goodman 20269903 Auxiliary Limit Auto Reset Switch

The Goodman 20269903 is a genuine OEM auxiliary auto-reset limit switch for the WGGE4336A045MAB gas furnace and compatible Goodman/Amana models. Mounted as a secondary thermal safety, this switch backs up the primary high limit by opening the control circuit if it senses excessive temperature at its location — for example near the burner box or blower compartment. It resets automatically once the sensed temperature falls back within the safe range.

Specifications

Type: Auxiliary auto-reset limit switch
Contact configuration: Normally closed (opens on temperature rise)
Function: Secondary overheat / rollout safety cutout
Fit: Goodman WGGE4336A045MAB and compatible furnaces
OEM Part Number: 20269903

OEM vs. Generic

As a redundant safety device, the auxiliary limit must trip at the exact temperature Goodman engineered for this model. The OEM 20269903 guarantees that calibration; generic substitutes with different setpoints can nuisance-trip or provide inadequate protection. OEM is strongly recommended for any life-safety switch.

Installation Difficulty

Easy (2/5). Screw-mounted with quick-connect terminals. Disconnect power before servicing. If the switch had tripped repeatedly, diagnose the cause (flame rollout, blocked flue, airflow issue) before restoring operation.
