Goodman 10123533 Manual Reset Limit Switch

The Goodman 10123533 is a genuine OEM manual-reset high-limit (rollout) safety switch built as a direct-fit replacement for the GMS950905DXA gas furnace and compatible Goodman/Amana models. Mounted at the burner or heat exchanger, it senses abnormal high temperature caused by flame rollout or blocked airflow and cuts the gas valve and ignition circuit to prevent overheating and fire.

Specifications

Type: Manual-reset high-limit / rollout safety switch
Reset: Manual push-button (must be reset by hand after a trip)
Function: Opens the control circuit on over-temperature
Mounting: Bracket-mount with 1/4" quick-connect terminals
Fits: Goodman GMS950905DXA and select 95% AFUE furnaces

OEM vs. Generic

This factory OEM Goodman switch is calibrated to your furnace's exact trip temperature and mounting footprint. Generic limit switches may use a different opening temperature or bracket geometry, leading to nuisance trips or improper protection. Because this is a life-safety device, we recommend the OEM part.

Common Symptoms of Failure

Furnace shuts down mid-cycle and requires a manual reset
Repeated rollout or limit fault codes
No heat after the switch has tripped and will not reset

Installation Difficulty: Easy

A quick 10–15 minute repair: disconnect power, unclip the two wires, unscrew the switch from its bracket, and install the new one in reverse. Important: if the switch keeps tripping after replacement, do not bypass it — a repeated trip signals a real problem such as a cracked heat exchanger, blocked flue, or dirty burners that requires a licensed HVAC technician.
