The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch engineered for the Goodman GKS90453BXAD gas furnace. Mounted on the heat exchanger bulkhead, this control continuously monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions.

Specifications

Part type: Primary high-limit temperature control
Function: Automatic-reset thermal safety cutoff
Fits: Goodman GKS90453BXAD gas furnace
Compatibility: OEM replacement for Goodman / Amana 20162904
Application: Residential gas furnace heat-exchanger limit protection

OEM vs. Generic

Our OEM Goodman control is calibrated to the exact trip and reset temperatures Goodman specifies for this furnace, guaranteeing correct high-limit protection and code-compliant operation. A generic aftermarket limit may carry a lower price but often uses a different trip point, risking nuisance lockouts or delayed shutoff. For a safety-critical component, we recommend the factory-matched OEM part.

Installation Difficulty

Moderate (2 of 5). A DIY-capable homeowner can complete the swap in 20–30 minutes with basic hand tools. Always shut off electrical power and the gas supply before servicing. Disconnect the two spade terminals, remove the mounting screws, install the new limit in the same orientation, and reconnect. If you are uncomfortable working near the burner assembly, contact a licensed HVAC technician.

Every part ships genuine Goodman OEM with fast, tracked delivery.
