The Goodman 10123535 manual reset limit switch — identified by its red reset button — is a genuine OEM safety control for GMH950905DXAD gas furnaces. It guards against overheat and flame-rollout conditions by opening the control circuit when temperature at its mounting location exceeds the safe setpoint, immediately shutting the furnace down. The red button color typically denotes a distinct trip temperature or mounting position from its companion switch (10123533), so it is important to match the correct part to the correct location.

OEM Part Number: 10123535
Category: High-limit / rollout safety switch
Type: Manual reset (red button)
Fits: Goodman GMH950905DXAD furnace
Function: De-energizes furnace on overheat/rollout
Fit type: Direct OEM exact-fit replacement

OEM vs. Generic: Color and part number encode a specific calibration on Goodman furnaces — mixing up the red (10123535) and its counterpart can cause nuisance shutdowns or leave a safety gap. Generic switches rarely match the exact setpoint and terminal layout. The authentic 10123535 ensures correct trip temperature, reliable protection, and warranty compliance.

Install difficulty: Easy (1/5). Budget 15–20 minutes. Shut off gas and electrical power, photograph and disconnect the wiring, remove the old switch, install the new 10123535 in the identical position and orientation, and reconnect the leads. Restore power and run a heat cycle. Repeated tripping signals an underlying airflow, venting, or heat-exchanger issue that must be corrected — never bypass a safety limit switch.
