Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 Primary Limit Switch is a genuine OEM high-temperature safety control for the AMH950703BXAF gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower housing, it opens the control circuit at its 150°F trip point to shut down the burners if airflow is lost or the plenum overheats — protecting the heat exchanger from cracking and preventing dangerous overheat conditions. A failed limit switch is a common cause of short-cycling, no-heat calls, and blower-runs-constantly symptoms.

OEM vs. Generic

Factory-calibrated to the exact 150°F set point your furnace's sequence of operation depends on. Generic limits with slightly off calibration cause premature nuisance trips or, worse, fail to open in time. OEM ensures correct terminal spacing, bracket geometry, and reliable snap-disc response.

Installation Difficulty

Easy (2/5). Two mounting screws and two spade terminals — typically a 10–15 minute swap. Cut power at the disconnect before servicing. Because this is a life-safety control, verify the replacement matches the original set point and mounting; when in doubt, use a licensed technician.
