The Lennox 92W94 (OEM reference R101083-02) is a genuine Lennox sequencer relay that stages electric heating elements with a 60–120 second ON delay and a 1–30 second OFF delay, preventing simultaneous element energization that could trip breakers or damage components. Symptoms of failure include no heat, insufficient heat output, or repeatedly tripped circuit breakers in your Lennox electric furnace or air handler. This direct OEM replacement matches the original timing specifications exactly, ensuring safe, efficient, and reliable staged heating performance.
