Brand: Goodman / Amana

OEM vs. Generic

A limit switch is a safety device — its trip temperature must match the furnace's engineered spec exactly. A generic switch with the wrong cutout point can either nuisance-trip (no heat) or fail to trip when it should (a genuine safety hazard). The OEM Goodman 20162906 is calibrated to the correct temperature and terminal layout for this furnace. For safety components, always use OEM.

Installation Difficulty

Moderate (3/5) — Requires shutting off power and gas, removing the burner/control panel, and transferring the two spade connectors. Use a multimeter to confirm the fault before replacing. If you're unsure about diagnosing furnace lockouts, have a licensed HVAC technician install this part.
