The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety for the Goodman GCH950703BXAC gas furnace. Mounted on the heat-exchanger/plenum, this primary limit continuously monitors supply-air temperature and opens the gas-valve circuit if the furnace overheats — most often from restricted airflow, a failed blower, or a dirty filter. It is the main over-temperature safeguard protecting the heat exchanger and preventing hazardous operation.

Specifications

Type: Primary high-limit temperature control (auto-reset)
Function: Opens gas circuit on plenum over-temperature
Mount: Furnace-specific bracket / setpoint
Fit: Direct OEM replacement for Goodman GCH950703BXAC
Brand: Goodman (genuine OEM)
Part number: 20162904

OEM vs. Generic

The genuine 20162904 is calibrated to Goodman's exact trip and reset temperatures for this furnace and uses the correct insertion depth and bracket. A generic limit with the wrong setpoint can either fail to protect the heat exchanger or cause repeated nuisance shutdowns. For a primary safety control, OEM is strongly recommended.

Install Difficulty

Moderate (3/5). Disconnect power, remove two mounting screws and the wiring, and transfer the connections to the new control. After installation, run a full heat cycle and verify the furnace does not trip under normal airflow. If the original tripped, correct the underlying airflow problem before returning to service.
