OEM vs. Generic

This is a factory-original Goodman OEM part, calibrated to the exact 300°F set point specified for your furnace. Generic aftermarket limit switches may carry a different trip temperature or mounting bracket, which can cause nuisance shutdowns or fail to protect the unit. For a critical safety control like a limit switch, OEM is the recommended choice.

Installation Difficulty

Easy — typically a two-wire spade connection and two mounting screws. Always disconnect power before servicing. If you're unsure of the cause of repeated limit trips, have an HVAC technician diagnose airflow first.
