OEM vs. Generic

Genuine Goodman limit switches are calibrated to the precise trip temperature specified for this furnace model. Generic substitutes may trip early (causing short cycling) or late (defeating the safety margin). Because this is a life-safety component, the OEM part is strongly recommended.

Installation Difficulty

Easy to Moderate — Typically two mounting screws and quick-connect terminals. Turn off power at the furnace disconnect before servicing. A basic multimeter helps confirm the old switch has failed open.
