OEM vs. Generic

Our OEM Goodman switch is factory-calibrated to the exact trip point your furnace control board expects, guaranteeing reliable safety shutdown. A lower-cost generic equivalent offers the same form and fit at a budget price, but trip tolerances can vary slightly. For a critical safety component, OEM is recommended; the generic is a solid value choice for the DIY repair.
