The Goodman 20162904 is a genuine OEM primary high-limit temperature control designed for the GCH950704CXAB gas furnace and compatible Goodman/Amana 96% AFUE models. This safety limit switch monitors heat-exchanger temperature and shuts off the burners if the furnace overheats, protecting the equipment and your home from unsafe operating conditions.

OEM vs. Generic

The genuine OEM 20162904 is factory-calibrated to the exact trip temperature Goodman engineered for this furnace, ensuring correct safety response and preserving your warranty. Aftermarket universal limits can carry the wrong temperature rating or bracket geometry, leading to premature tripping or unsafe operation. For a safety-critical component, OEM is strongly recommended.

Installation Difficulty

Moderate. Requires removing the burner-compartment panel and disconnecting two wire leads. Always shut off gas and power first. Most DIYers with basic tools can complete the swap in 20–30 minutes; if you are unsure, consult a licensed HVAC technician.
