OEM vs. Generic

The genuine OEM switch is factory-calibrated to the exact trip temperature specified for your furnace, ensuring reliable safety shutdown and correct auto-reset behavior. Generic universal limits often carry wider tolerances and mismatched mounting, which can cause nuisance trips or fail to protect the heat exchanger. For a safety component, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). A qualified technician can swap this switch in minutes: disconnect power, remove the two spade terminals, unscrew the mounting bracket, and reverse. Always shut off electrical and gas supply before servicing.
