The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit control rated for a 150°F trip point, built for the Goodman/Amana AMSS960603BNAA gas furnace. Mounted on the heat-exchanger bulkhead, this switch continuously senses supply-air temperature and opens the burner circuit if airflow is lost or the plenum overheats — protecting the heat exchanger from cracking and preventing unsafe operation. Unlike a manual-reset switch, the primary limit is auto-resetting: it closes again once temperatures return to normal, allowing the furnace to resume automatically.

Part Type: Auto-reset primary high-limit switch
Trip Temperature: 150°F (open on rise)
OEM Part #: 20162903
Fits: Goodman/Amana AMSS960603BNAA gas furnace
Circuit: Normally closed, auto-reset

OEM vs. Generic: Trip temperature and bracket geometry are model-specific. The OEM 20162903 is factory-calibrated to 150°F and mounts flush to the AMSS960603BNAA bulkhead. A generic switch with the wrong setpoint will cause short-cycling on limit or, dangerously, fail to protect the exchanger. For correct furnace behavior, choose the genuine Goodman part.

Install Difficulty: ⭐⭐ Easy (2/5) — cut power, note wire positions, remove two mounting screws, transfer the spade connectors, and reinstall. A multimeter confirms continuity at room temperature. Turn off the breaker before servicing.
