The Goodman 10123518 Manual Reset Limit Switch is a genuine OEM high-limit safety control for the GMV950453BXAB gas furnace. This switch monitors heat-exchanger and rollout temperatures and opens the control circuit if the furnace overheats, protecting your equipment and home from unsafe conditions. Because it is a manual-reset design, it must be physically reset after a trip — a deliberate safety feature that flags an underlying airflow or combustion problem.

OEM vs. Generic

Safety controls are one place to never gamble on a generic. This genuine Goodman switch is calibrated to the exact trip temperature specified for the GMV950 heat exchanger. Off-brand switches with the wrong set point can either nuisance-trip or, worse, fail to open when needed. Buy OEM for guaranteed calibration and terminal fit.

Installation Difficulty

Easy — Two spade terminals and typically two mounting screws. Shut off power, note wire positions, swap the switch, and reset. Estimated time: 10–15 minutes. If the switch keeps tripping after replacement, investigate airflow (dirty filter, blocked vent) rather than repeatedly resetting.

Genuine OEM part with same-day shipping on in-stock orders.
