Genuine Goodman 20269903 Auxiliary Auto-Reset Limit Switch

The OEM Goodman 20269903 is an auxiliary auto-reset limit switch for the WGGE4342A070MAB furnace. It provides secondary overheat protection — commonly guarding the blower or secondary heat-exchanger area — and opens the control circuit if temperature exceeds its rated setpoint. Because it is auto-reset, the switch closes again automatically once the area cools, allowing normal operation to resume without manual intervention.

Specifications

Part Number: 20269903
Type: Auxiliary auto-reset limit switch
Reset: Automatic (self-resetting on cooldown)
Function: Secondary overtemperature safety cutout
Fit: Goodman WGGE4342A070MAB (verify against your model)

OEM vs. Generic

Genuine Goodman switches carry the precise trip and reset temperatures specified for your furnace. Generic auto-reset switches risk nuisance cycling or delayed protection. For a safety-critical control, OEM is the reliable choice.

Install Difficulty

Moderate — disconnect two spade terminals and unscrew the switch from its mounting. Cut power before service. Repeated tripping usually points to restricted airflow (dirty filter, blower, or coil) — correct the root cause, not just the switch.
