Goodman 10123533 Manual Reset Limit Switch

The Goodman 10123533 is a genuine OEM manual-reset high-limit safety switch built for the WGFM195045S3BAB gas furnace. This thermally activated cutout opens the ignition/burner circuit if the heat exchanger or blower compartment exceeds a safe temperature, protecting your furnace and home from overheating due to restricted airflow, a dirty filter, or blower failure. Because it is a manual reset design, it must be physically reset after tripping — a deliberate safeguard that forces a technician to identify the root cause.

Specifications

OEM Part Number: 10123533
Type: Manual reset high-limit / rollout safety switch
Reset: Push-button manual reset
Fit: Goodman WGFM195045S3BAB (verify existing part number)
Equipment: Gas furnace

OEM vs. Generic

OEM Goodman limit switches are calibrated to the exact trip temperature specified for your furnace. Because this is a life-safety component, we strongly recommend the genuine OEM part over generic substitutes that may trip early, trip late, or not fit the factory bracket.

Installation Difficulty: Easy

Replacement usually takes 10–20 minutes with a nut driver and pliers. Cut power and gas first, note the wire positions, and mount the new switch in the same orientation against the metal it senses. If the switch keeps tripping after replacement, stop and diagnose the airflow or heat exchanger issue rather than defeating the safety.

Confirm your existing part number before ordering — see also red-cap variant 10123535.
