The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety switch for the Goodman GKS90904CXAE gas furnace. This high-limit control continuously monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger, blower, and your home from dangerous conditions. If your furnace short-cycles, trips on limit, or won't fire, a failed primary limit is a frequent culprit.

OEM vs. Generic

The OEM Goodman limit control is factory-calibrated to the exact trip and reset temperatures this furnace requires. Because this is a life-safety component, an incorrectly rated generic switch can either nuisance-trip or, worse, fail to open at the proper temperature. We recommend OEM for all safety controls.

Installation Difficulty

Moderate (2/5) — Disconnect power, remove the two mounting screws and wiring connectors, and install the replacement in the same orientation. Basic hand tools only. Typical time: 15-20 minutes.
