The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM safety control engineered for the AMVC950704CXAE 95% AFUE variable-speed gas furnace. This high-limit switch monitors heat-exchanger temperature and opens the gas valve circuit if the furnace overheats — protecting your equipment and home from unsafe operating conditions. As a manual-reset device, it must be physically reset after a trip, prompting the homeowner or technician to investigate the root cause (blocked airflow, failed blower, or dirty filter).
This is the factory OEM part, calibrated to the exact trip temperature specified for the AMVC950704CXAE. Generic universal limits often carry incorrect setpoints, which can cause nuisance lockouts or fail to protect the heat exchanger. Choosing OEM guarantees correct calibration, terminal fit, and warranty compliance.
Rating: Moderate (2/5). A two-wire swap on the vestibule panel, typically 15–20 minutes. Always shut off power and gas before servicing. If tripping recurs after replacement, have a licensed HVAC technician diagnose the underlying airflow or combustion fault.
