The 20269903 Auxiliary Limit Auto‑Reset Switch is an OEM safety component used in Goodman and Amana furnace systems. Designed to open (interrupt the circuit) at approximately 150 °F, this limit switch provides backup protection by cutting power when temperatures exceed safe thresholds. Once the system cools, it automatically resets—eliminating the need for manual resets.
Features:
- Automatic Reset Design — Opens at ~150 °F to safeguard against overheating, then resets once temperatures return to safe levels.
- OEM Compatibility — Fully compatible with Goodman and Amana furnace models originally designed with the 20269903 limit switch.
- Compact & Robust Construction — Made to handle repeated thermal cycling in the furnace environment.
