Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control engineered as a direct-fit replacement for the GCH950703BXAA 96% AFUE gas furnace. This safety-critical component continuously monitors heat-exchanger and plenum air temperature, cutting power to the gas valve and burners if the furnace overheats due to restricted airflow, a dirty filter, or a failed blower. A functioning limit control is essential to safe furnace operation and to protecting the heat exchanger from thermal damage.

OEM vs. Generic

This is the factory-spec Goodman part, calibrated to the exact trip temperature your GCH95 furnace was designed around. Generic or universal limit switches often use approximate trip points and mounting patterns, which can cause nuisance shutdowns or, worse, fail to trip at the correct temperature. Choosing the OEM 20162904 guarantees correct calibration, fit, and safety compliance.

Installation Difficulty: Easy–Moderate

Replacement typically takes 20–30 minutes with basic hand tools. Always disconnect power to the furnace before servicing. Note the wiring and mounting orientation of the old switch, transfer the leads to the new control, and secure it to the same location. If you are not comfortable working around gas appliances and 120V wiring, we recommend a licensed HVAC technician.

Genuine Goodman OEM part backed by manufacturer quality.
