Genuine Goodman/Amana 10123533 manual reset high-limit switch, a direct-fit safety component for the AMVC950905CXAB 95% AFUE modulating furnace and related Goodman/Amana models. This normally-closed thermal switch opens the ignition circuit if the heat exchanger or burner compartment exceeds its rated cutout temperature, protecting against overheating and flame rollout. Because it is a manual-reset device, a tripped switch must be pressed to reset after the underlying cause (restricted airflow, blocked flue, dirty filter) is corrected.
The OEM switch is calibrated to the exact factory cutout temperature for safe, code-compliant operation — recommended for any safety device. A Generic equivalent matches the mounting and terminals at a lower cost; verify the temperature rating matches before substituting on a safety limit.
Easy (1/5) — Two mounting screws and two push-on terminals. Disconnect power, note wire positions, swap the switch, and reset. About 15 minutes with a nut driver.
