Genuine Goodman 10123535 Manual Reset Limit Switch (Red)

The Goodman 10123535 is a factory OEM red-button manual reset limit switch for the GKS90905DXAD gas furnace. Like all high-limit safeties, it interrupts the burner circuit on an overheat or flame-rollout condition, but it is calibrated to a different trip temperature than its companion switch — the red button and part number identify the correct setpoint for its mounting location. Using the right-rated switch is essential for proper protection.

Specifications

Goodman OEM part number: 10123535
Component: High-limit / rollout safety switch
Reset type: Manual (red push-to-reset button)
Equipment: Gas furnace (90%+ AFUE)
Fits model: GKS90905DXAD
Fit type: Direct exact-fit replacement

OEM vs. Generic

The red-button rating exists precisely because setpoint matters. Substituting a generic or wrong-color switch changes the temperature at which the furnace shuts down, risking nuisance lockouts or unsafe operation. The OEM 10123535 matches Goodman's specified trip point and terminal layout for a true drop-in fit. OEM is the recommended choice for this safety component.

Install Difficulty

Easy. About 10–20 minutes: cut power, photograph and transfer the wiring, remove the mounting screws, install the new switch in the same location, and reconnect. Confirm you are replacing like-for-like by part number, then investigate the root cause (airflow, venting) before restoring heat.
