The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the GMH950904CXAG 96% AFUE gas furnace. This control continuously monitors heat-exchanger and plenum temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a cracked heat exchanger. It is one of the furnace's most important safety devices, and a failed limit will cause no-heat or repeated lockout conditions.

Specifications

Part type: Primary high-limit temperature control
Function: Automatic overheat cutout, resets on cool-down
Mounting: Factory bracket to furnace vestibule/plenum
Fits: Goodman GMH950904CXAG and compatible furnace models

OEM vs. Generic

The trip and reset temperatures are calibrated to this specific furnace platform. The OEM 20162904 guarantees the correct set point and mounting geometry. Generic limits with the wrong trip temperature can either nuisance-trip or, worse, fail to protect the unit. For a safety component, OEM is strongly recommended.

Installation Difficulty: Moderate

Disconnect power, note the wiring, remove the two mounting screws, transfer the leads to the new 20162904, and remount. A multimeter helps confirm continuity. Most techs complete this in 20–30 minutes.
