The genuine OEM Goodman 10123533 manual reset limit switch is a high-temperature safety control for the Goodman WGFM195045S3BAC gas furnace. This normally-closed thermal switch opens the ignition/gas circuit if the heat exchanger or burner area exceeds its rated trip temperature, shutting the furnace down to prevent overheating, cracked heat exchangers, and fire hazards. Its manual-reset design requires a technician to physically press the button after a trip — a deliberate safeguard that flags an underlying airflow or venting problem rather than silently cycling.

Specifications

OEM Part Number: 10123533
Type: Manual reset high-limit / rollout safety switch
Action: Normally closed, opens on over-temperature
Reset: Manual (push-button)
Fits: Goodman WGFM195045S3BAC furnace

OEM vs. Generic

The OEM 10123533 is calibrated to the exact trip temperature Goodman specifies for this model, so it protects the heat exchanger without nuisance tripping. Generic switches with approximate temperature ratings can trip early (no heat) or trip late (unsafe). For a life-safety component, matching the factory rating is essential.

Installation Difficulty

Easy to Moderate. Cut power and gas, disconnect the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. About 15 minutes. Because a tripped limit indicates a root-cause issue (dirty filter, blocked vent, failing blower), have a technician diagnose the cause during replacement.
