OEM Goodman 10123519 Manual Reset Limit Switch

The Goodman 10123519 is a factory-original manual reset high-limit switch for the GMS951155DXA 95% AFUE gas furnace. This safety control monitors heat-exchanger and cabinet temperature and cuts power to the gas valve if the furnace overheats — protecting against blocked airflow, dirty filters, or blower failure. As a manual reset device, it must be physically reset after a trip, alerting the homeowner or technician to an underlying problem rather than silently recycling.

Specifications

OEM Part Number: 10123519
Type: Manual reset high-limit switch
Compatible Model: GMS951155DXA (115,000 BTU class)
Function: Over-temperature safety shutoff
Equipment Type: Gas Furnace

OEM vs. Generic

Limit switches are matched to a specific temperature setpoint and mounting footprint. This genuine Goodman OEM switch trips at the exact factory-specified temperature, ensuring reliable overheat protection and a clean bolt-in fit. Generic switches with incorrect setpoints can either nuisance-trip or fail to protect the heat exchanger. For a critical safety component, OEM is the recommended choice.

Installation Difficulty

Easy (2/5). Disconnect power, remove the two mounting screws and spade connectors, and install the replacement in the same orientation. About 15 minutes with basic tools. If the new switch trips, diagnose the airflow or heat-exchanger issue before returning to service.
