The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety component engineered for the Goodman GMH950904CXAF 95% AFUE two-stage gas furnace and compatible GMH95 series models. This normally-closed thermal limit switch continuously monitors heat-exchanger and plenum temperatures, cutting power to the gas valve if the furnace exceeds its safe operating range — protecting your equipment and home from overheating caused by restricted airflow, a dirty filter, or a failed blower.

Function: Normally-closed thermal safety cutout

OEM vs. Generic

This is a factory-original Goodman part, calibrated to the exact trip temperature specified for your furnace's heat exchanger. Universal aftermarket limits often carry different set points and can nuisance-trip or fail to protect properly. Choosing OEM guarantees correct calibration, terminal orientation, and mounting fit — no guesswork.

Installation Difficulty: Easy (2/5)

Replacement is straightforward for a handy homeowner or HVAC tech: shut off power and gas, remove the two mounting screws, transfer the wire leads to the new switch, and reinstall. Always confirm the underlying cause of a tripped limit (airflow restriction, blower fault) before returning the furnace to service. Professional installation is recommended if you are unfamiliar with gas appliance safety.

Genuine Goodman OEM replacement — backed by correct-fit assurance for the GMH950904CXAF.
