The Goodman 20162903 Primary Limit Switch is a genuine OEM high-temperature safety control rated at 150°F, designed for Goodman GKS90704CXAE gas furnaces. This limit switch monitors heat-exchanger temperature and opens the circuit to shut down the burners if the furnace overheats — protecting the heat exchanger and your home. A failed or nuisance-tripping limit switch is a frequent cause of short cycling and no-heat calls.

OEM vs. Generic

Limit switches are life-safety components, and the trip temperature must match your furnace's design. This genuine Goodman OEM switch is calibrated to the exact 150°F set point your furnace expects. Generic switches with an approximate rating can trip early (causing no heat) or too late (risking heat-exchanger damage). We strongly recommend OEM for any safety control.

Installation Difficulty

Easy to Moderate (2 of 5). The switch mounts with two screws and two spade terminals. Shut off gas and power, note wire positions, and swap the switch. Verify operation after install. If in doubt, use a licensed HVAC technician.

Ships fast and backed by our exact-fit guarantee.
