The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM high-limit safety control for the GMH950905DXAA 95% AFUE gas furnace. This switch monitors heat-exchanger and plenum temperature and shuts off the gas valve if the furnace overheats — protecting the unit and your home from unsafe conditions. Because it is a manual-reset device, it must be physically reset after a trip, which flags a persistent problem (such as restricted airflow or a dirty filter) for correction.

Specifications

OEM part number: 10123533

OEM vs. Generic

Genuine OEM 10123533 switches use the exact trip temperature and mounting geometry specified for your furnace. Generic look-alikes can carry the wrong set point, causing nuisance trips or — worse — failing to trip when needed. For a safety control, factory-matched calibration matters.

Installation Difficulty: Moderate

Requires disconnecting power, removing the burner/blower access panel, disconnecting two wire leads, and unscrewing the switch bracket. Basic hand tools and a meter for continuity testing are recommended. Always shut off gas and electric before servicing.
