The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutoff for the GMS950453BXA gas furnace. This normally-closed switch opens and shuts off the burners if it senses an overheat or flame-rollout condition, protecting the heat exchanger and household. Because it is manual reset, it must be pressed to close again after a trip — a repeat trip signals an underlying airflow or combustion fault that should be diagnosed.

Part Type: Manual reset high-limit / rollout safety switch
Fits Model: Goodman GMS950453BXA furnace

OEM vs. Generic

The genuine Goodman OEM switch is factory-calibrated to the exact cutout temperature the GMS950453BXA requires. A generic switch with the wrong trip point can nuisance-trip or, worse, fail to protect the furnace. OEM guarantees correct temperature calibration, mounting bracket fit, and terminal spacing.

Installation Difficulty

Easy. Remove power, unplug the two spade terminals, unscrew the switch, and mount the replacement in the same orientation. About 15 minutes. If the switch tripped, find and fix the root cause (dirty filter, blocked flue, failing blower) before returning the furnace to service.
