The Goodman 20162903 Primary Limit Switch (150°F) is a genuine OEM safety control for the GMH950704CXAB and related Goodman/Amana gas furnaces. Mounted on the heat exchanger or blower housing, this normally-closed thermal switch opens the circuit if supply-air temperature exceeds its rated limit, shutting down the burners to prevent heat-exchanger damage and overheating. If your furnace short-cycles on high limit or fails to fire, a faulty limit switch is a common cause.

OEM Part Number: 20162903
Trip Temperature: 150°F (open on rise)
Type: Normally-closed primary high-limit switch, auto-reset
Compatible Model: GMH950704CXAB (and related Goodman/Amana furnaces)

OEM vs. Generic

OEM Goodman limit switches are calibrated to the exact trip temperature specified for your furnace's heat exchanger. Generic switches may carry a similar temperature rating but differ in reset behavior, bracket geometry, and calibration accuracy — a mismatch on a safety control can lead to nuisance trips or unsafe operation. We recommend OEM for this critical component.

Installation Difficulty

Easy (1/5). Usually a two-screw, two-wire swap taking under 20 minutes. Cut power at the disconnect first and note wire positions before removal. When in doubt, use a licensed HVAC technician.
