OEM Goodman Manual Reset Limit Switch (Red) for GMH950703BXAF — 10123535

Goodman 10123535 Manual Reset Limit Switch (Red)

The genuine OEM Goodman 10123535 is a red manual reset high-limit safety switch used on the GMH950703BXAF 96% AFUE two-stage gas furnace and compatible Goodman/Amana equipment. The red housing typically denotes a higher trip temperature than the companion 10123533, positioning it as a secondary or rollout/limit safety on the burner assembly. When temperatures exceed the rated set point, the switch opens the control circuit and de-energizes the furnace to protect the heat exchanger and surrounding components.

OEM vs. Generic

The OEM 10123535 is factory-matched to the correct trip temperature and terminal layout for your furnace. Substituting a generic switch with a different set point can either mask a dangerous condition or cause repeated nuisance shutdowns. For flame-rollout and high-limit protection, always use the genuine Goodman part.

Installation Difficulty

Rating: Easy–Moderate (2/5). Replacement takes about 15–20 minutes. Cut power and gas, transfer the wire leads to the new switch, and secure it in the original bracket. A repeated trip indicates a combustion or airflow fault — inspect the burners, vent, and blower before restoring operation.
