The Goodman 10123518 Manual Reset Limit Switch is a genuine OEM high-limit safety control for GMV950453BX series 96% AFUE gas furnaces. This normally-closed thermal switch opens the ignition circuit if it detects an overheat condition — such as a blocked flue, dirty filter, or failed blower — shutting the furnace down to prevent heat-exchanger damage and fire hazard. Because it is a manual reset switch, it must be physically reset (button) after a trip once the fault is corrected.

Part Type: Manual reset high-limit / rollout safety switch
OEM Part Number: 10123518
Fits: Goodman GMV950453BX high-efficiency furnaces
Configuration: Normally closed (opens on overheat)
Reset: Manual push-button reset

OEM vs. Generic

This genuine OEM Goodman switch is factory-calibrated to the correct trip temperature for the GMV950453BX. Because this is a safety device, an incorrectly rated generic switch can trip prematurely or — worse — fail to trip when needed. Always match the exact OEM specification on limit controls.

Install Difficulty

Easy (1/5) — A quick swap requiring only a nut driver. Shut off power, disconnect the two wire leads, remove the mounting screws, install the new switch in the same orientation, reconnect the leads, and restore power. Verify the furnace completes a full heat cycle. Note: if the switch keeps tripping, diagnose and correct the underlying airflow or venting fault.

Safety component — disconnect power before servicing. Consult a licensed HVAC technician if unsure.
