Goodman 10123535 Manual Reset Limit Switch

The Goodman 10123535 is a genuine OEM manual-reset rollout limit switch (identified by its red reset button) engineered for the GMH950453BXAD 95% AFUE gas furnace and other compatible Goodman and Amana models. This safety control monitors the burner and heat-exchanger area for flame rollout or abnormal heat, opening the gas-valve circuit to shut the furnace down before an unsafe condition develops.

Specifications

Type: Manual reset flame rollout / limit switch
Reset: Manual (red push-button)
Function: Normally closed, opens on high temperature
Fits: Goodman GMH950453BXAD and compatible Goodman/Amana furnaces
Part number: 10123535 (OEM)

OEM vs. Generic

Our OEM 10123535 is the factory-specified part with the exact trip temperature and terminal layout your furnace's safety circuit was designed around. Generic aftermarket switches may use a different set point or bracket, risking nuisance trips or an improper fit. For a safety-critical control like a rollout switch, we recommend the OEM part.

Installation Difficulty

Easy (2/5). Two spade terminals and a single mounting screw or clip. Always shut off power and gas before servicing. If this switch has tripped, diagnose the underlying cause (blocked flue, cracked heat exchanger, or restricted venting) before returning the unit to service. Professional installation recommended when in doubt.
