The Goodman 10123533 manual reset limit switch is a genuine OEM safety control for GMH950905DXAD gas furnaces. This high-limit switch monitors temperature at the heat exchanger or burner area and opens the circuit if it detects an overheat or flame-rollout condition, shutting down the furnace to prevent damage and hazards. As a manual-reset device, it stays open until a technician physically presses the reset button — a deliberate design that forces inspection of the root cause before the furnace can run again.

OEM Part Number: 10123533
Category: High-limit / rollout safety switch
Type: Manual reset
Fits: Goodman GMH950905DXAD furnace
Function: Opens on overheat/rollout to de-energize the furnace
Fit type: Direct OEM exact-fit replacement

OEM vs. Generic: Limit switches are calibrated to a specific trip temperature. A generic switch with the wrong setpoint either nuisance-trips or, worse, fails to trip when it should — defeating a critical safety function. The genuine Goodman 10123533 carries the correct factory calibration and terminal configuration, protecting occupants and preserving warranty compliance.

Install difficulty: Easy (1/5). Allow 15–20 minutes. Turn off gas and power at the furnace, note and disconnect the wire terminals, unscrew the old switch, mount the new 10123533 in the same orientation, and reconnect the leads. Restore power, press the reset if needed, and run a heat cycle to confirm normal operation. If the switch trips again, investigate airflow, venting, or a blocked heat exchanger before repeat resets.
