OEM vs. Generic

The OEM 10123533 is calibrated to the exact trip temperature specified for this furnace's heat exchanger and mounting location. Generic limit switches often carry incorrect set points or bracket patterns, risking nuisance trips or — worse — a switch that fails to protect the equipment. For a safety-critical control, genuine Goodman is the right call.

Installation Difficulty

Easy (2/5). Typically a two-wire swap on a bracket; 15–20 minutes. Cut all power first, photograph wiring, and never bypass a limit switch to keep a furnace running.
