It opens the heating circuit on an overheat event and holds open until manually reset.

OEM vs. Generic

The red 10123535 is set to a distinct temperature threshold — do not substitute it with the standard limit switch or a generic equivalent. Using the wrong set point defeats the layered safety design Goodman built into the GMH950905DXAB. The OEM part guarantees the correct trip point and terminal fit.

Install Difficulty

Easy (2/5). Note the switch location, disconnect the terminals, swap the switch in the same orientation, and reconnect. Cut power and gas before servicing, and press the red reset button once installed. When in doubt, have a licensed HVAC technician confirm the correct part placement.
