Description
The Lennox 12J16 Heat Sequencer is a genuine OEM replacement component engineered to deliver precise, staged control of heating elements in Lennox electric furnaces and air handlers. By staggering the activation of individual heating elements, this sequencer prevents simultaneous power draws that can trip breakers or overload electrical circuits — ensuring smooth, reliable heating performance season after season.
How It Works
Heat sequencers use a bimetal element that heats and deflects when current is applied, opening or closing contacts in a timed sequence. This staged switching action distributes the electrical load across multiple heating elements, protecting your system’s wiring and breaker panel while improving overall comfort delivery.
