The Goodman 10123535 Manual Reset Limit Switch (Red) is a genuine OEM high-temperature safety cutoff for the GMS950453BXA gas furnace. The red button designates a specific trip temperature in the furnace's safety chain — do not substitute a different color, as the color codes the cutout setpoint. This normally-closed switch interrupts the burner circuit on an overheat or flame-rollout event and must be manually reset after a trip.

Specifications

OEM vs. Generic

The genuine Goodman OEM switch carries the correct factory trip point marked by its red button. Installing a generic switch or the wrong color can defeat the layered safety design of the GMS950453BXA and lead to nuisance shutdowns or an unprotected heat exchanger. OEM ensures the exact calibration, bracket, and terminal fit.

Installation Difficulty

Easy. Cut power, pull the spade terminals, unscrew and replace the switch in the identical position, then reconnect. Roughly 15 minutes. A tripped safety switch always points to an underlying problem — verify airflow and combustion before restoring heat.
