Goodman 10123535 Manual Reset Limit Switch — Red

The Goodman 10123535 is a genuine OEM red-body manual reset limit switch for the GMH950453BXAC 95% AFUE gas furnace. The red housing distinguishes it from the companion 10123533 unit and typically denotes a different trip temperature or mounting location within the furnace's layered safety-limit system. It opens the heating circuit on an over-temperature condition and requires a manual reset, ensuring a technician inspects the cause before the furnace restarts.

Specifications

OEM Goodman part number: 10123535
Component: Manual reset high-limit switch (red body)
Type: Snap-disc thermal cutoff, manual reset button
Compatible model: GMH950453BXAC (95% AFUE furnace)
Function: Over-temperature safety shutoff

OEM vs. Generic

Because the red and standard switches are calibrated to different set points, using the wrong device — or a generic with an unknown trip temperature — can defeat the furnace's staged safety protection. This factory Goodman part guarantees the correct color-coded trip rating and terminal layout.

Install Difficulty

Easy (1/5). A quick spade-terminal and two-screw swap. Cut power, match the red switch to its original location, transfer wiring, and mount. Confirm the reason for any trip before restoring heat.

Disconnect power before servicing. Repeated trips indicate an airflow or heat-exchanger issue — consult a licensed HVAC technician.
