Goodman 10123535 Manual Reset Limit Switch (Red)

The Goodman 10123535 is a genuine OEM red-cap manual-reset limit/rollout safety switch for the WGFM195045S3BAB gas furnace. The red button identifies this switch's specific trip temperature and mounting position, distinguishing it from the companion 10123533. It opens the burner circuit on an over-temperature or flame-rollout condition, shutting the furnace down until the underlying fault is corrected and the button is manually reset.

Specifications

OEM Part Number: 10123535
Type: Manual reset high-limit / flame-rollout safety switch
Cap Color: Red (trip-point identifier)
Reset: Push-button manual reset
Fit: Goodman WGFM195045S3BAB (verify existing part number)

OEM vs. Generic

The red versus non-red distinction matters: each color corresponds to a factory-set trip temperature and location on the furnace. Installing the wrong switch can cause nuisance shutdowns or, worse, fail to protect against rollout. Always match the color and part number — this genuine OEM part guarantees the correct calibration and fit.

Installation Difficulty: Easy

Expect 10–20 minutes with basic tools. Disconnect power and gas, photograph the wiring, and install the replacement in the identical position and orientation. Do not swap the red and non-red switches. If the switch trips repeatedly, diagnose airflow, the heat exchanger, or a rollout condition before returning the furnace to service.

Verify the part number and cap color on your current switch before ordering.
