Goodman 20269903 Auxiliary Auto Reset Limit Switch

The 20269903 is a genuine OEM Goodman auxiliary limit switch with automatic reset for WGGE4537A090MAA gas/electric package units. Mounted as a secondary overheat/rollout safeguard, this bi-metal snap-disc opens the control circuit if it detects excessive temperature — for example from flame rollout or a blocked flue — and automatically closes again once conditions return to normal. It backs up the primary high-limit to give the furnace layered thermal protection.

Direct-fit for WGGE4537A090MAA

OEM vs. Generic

As a safety device, the auxiliary limit must trip at Goodman's specified temperature to protect the heat exchanger and occupants. Generic replacements may carry a different calibration or terminal layout, compromising protection or fit. The OEM 20269903 matches the factory trip point and mounting exactly, ensuring the safety chain performs as designed.

Installation Difficulty

Easy — typically two screws and two push-on terminals. Plan 15–20 minutes with basic hand tools. Always disconnect power and shut off gas before servicing. If this switch trips repeatedly, investigate the root cause (rollout, blocked venting, or airflow) rather than replacing it in a loop.

Compatible model: WGGE4537A090MAA. Verify part number 20269903 on your existing switch before ordering.
