The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the Goodman GKS90453BXAF gas furnace and compatible GKS90 series models. Mounted on the heat-exchanger/blower deck, it continuously monitors plenum temperature and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. This auto-reset control is the furnace's primary overheat protection and a common failure point on aging systems.

Specifications

Type: Primary high-limit temperature control (auto-reset snap-disc)
Function: Plenum overheat / high-limit burner cutoff
Terminals: 1/4 in. quick-connect spades
Mounting: Bracket-mount to blower/heat-exchanger deck
Fits: Goodman GKS90453BXAF and select GKS90 furnaces
OEM Part No.: 20162904

OEM vs. Generic

The OEM primary limit is factory-calibrated to the furnace's exact trip temperature and mounting geometry. Generic universal limits require field adjustment and can trip early or fail to protect if mismatched. For this safety-critical control, the genuine Goodman part is strongly recommended.

Install Difficulty

Easy (2/5) — Disconnect power and gas, unplug the two spade terminals, remove the mounting screws, and install the new control in the same position and orientation. Roughly 15 minutes for a qualified technician; verify normal cycling after replacement.
