Goodman 10123518 Manual Reset Limit Switch

The Goodman 10123518 is a genuine OEM manual reset high-limit safety switch designed for the GMV950453BXBB gas furnace and compatible Goodman/Amana models. This switch protects your furnace from dangerous overheating by cutting power to the gas valve when the plenum temperature exceeds a safe threshold. Because it is a manual reset unit, it requires a technician to physically press the reset button after a trip — a deliberate safety feature that flags an underlying airflow or heat-exchanger issue rather than silently cycling.

OEM vs. Generic

Our OEM version is the exact Goodman-specified part with a factory-calibrated trip temperature — the safest choice for warranty and precise operation. A generic equivalent can lower cost while meeting the same temperature rating, but always confirm the trip setpoint before installing a safety control.

Installation Difficulty

Easy (2/5). Two-wire connection with a single mounting screw. Always shut off power and gas before servicing. If the switch keeps tripping, diagnose airflow (dirty filter, blocked vents) before replacing.
