Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 Primary Limit Switch is a genuine OEM high-temperature safety control designed for the Goodman GKS90703BXAH gas furnace and compatible Goodman/Amana models. Rated to open at approximately 150°F, this thermal limit switch monitors heat-exchanger and plenum temperatures and shuts off the burners if the furnace overheats — a critical safety function that prevents heat-exchanger damage and unsafe operating conditions. If your furnace short-cycles, trips on limit, or fails to fire, a faulty limit switch is a common cause.

OEM vs. Generic

The OEM Goodman limit switch is factory-calibrated to the exact 150°F setpoint your furnace's control board expects. Because this is a safety component, we strongly recommend OEM — generic switches can have setpoint tolerance drift, leading to nuisance trips or, worse, failure to protect against genuine overheating.

Installation Difficulty

Rating: Easy to Moderate. Two-wire spade connection and a couple of mounting screws. Turn off power first and note wire orientation. Estimated time: 15–25 minutes. DIY-friendly for handy owners; when in doubt, use a technician.
