The Goodman 10123535 Manual Reset Limit Switch (Red) is a genuine OEM high-limit safety control for GMV950453BX series 96% AFUE gas furnaces. The red-button manual reset switch is a normally-closed thermal safety that opens the control circuit on an overheat or flame-rollout event, shutting the furnace down to protect the heat exchanger and prevent unsafe operation. The distinctive red reset cap denotes this switch's specific trip rating within the furnace's safety chain — do not substitute it for a different-color/temperature switch.

OEM Part Number: 10123535
Fits: Goodman GMV950453BX high-efficiency furnaces
Configuration: Normally closed (opens on overheat)
Reset: Manual red push-button reset

OEM vs. Generic

This genuine OEM Goodman switch is factory-calibrated to the exact trip temperature specified for its position in the GMV950453BX. On safety controls, matching the OEM rating is essential — a mismatched generic switch may nuisance-trip or fail to protect the equipment. The color coding exists to prevent installing the wrong-temperature switch.

Install Difficulty

Easy (1/5) — A simple nut-driver replacement. Power down the furnace, note the wire and orientation, disconnect the leads, unscrew the old switch, mount the new red-reset switch identically, reconnect, and restore power. Run a full heat cycle to confirm normal operation. Repeated tripping indicates an airflow or venting problem that must be addressed.

Safety component — always disconnect power before servicing. When in doubt, hire a licensed HVAC professional.
