OEM vs. Generic

As a safety device, exact calibration matters. The genuine OEM Goodman 20162903 trips at the factory-specified 150°F, ensuring the furnace shuts down at the correct threshold. Generic limits with drifted set points can trip early (frequent lockouts) or too late (overheating risk). OEM protects both safety and warranty coverage.

Installation Difficulty

Moderate (2/5) — Mounts to the heat-exchanger/blower panel with two screws and two spade connectors. Shut off power before servicing and photograph wiring before disconnecting. If the old limit tripped repeatedly, have a technician diagnose the root cause (airflow/heat exchanger).
