Goodman 10123533 Manual Reset Limit Switch

The Goodman 10123533 is a genuine OEM manual-reset high-limit safety switch for the GKS90905DXAF gas furnace. This normally-closed thermal switch opens the control circuit if the furnace overheats or a flame rollout condition occurs, shutting down the gas valve to protect the heat exchanger and prevent unsafe operation. Because it is a manual-reset device, it locks out until pressed, alerting the technician that an overheat event occurred rather than silently cycling.

Specifications

OEM Part #: 10123533
Part Type: Manual-reset high-limit / rollout switch
Action: Normally closed, opens on overtemperature
Reset: Manual (push-button)
Fits Model: GKS90905DXAF (and compatible Goodman furnaces)

OEM vs. Generic

The OEM Goodman switch is calibrated to the factory trip temperature for the GKS90905DXAF and is the safest choice for a safety control. A generic equivalent can save money on out-of-warranty jobs, but verify the trip point and terminal orientation match. For a safety-critical limit switch, OEM is strongly recommended.

Installation Difficulty

Easy–Moderate (2/5). Disconnect power and gas, note wiring, unscrew the switch from the burner box or heat-exchanger bracket, transfer the terminals, and mount the replacement. Takes 10–15 minutes. If the switch keeps tripping after replacement, diagnose the underlying overheat cause (dirty filter, blower, or restricted airflow).
