Description
The Lennox 22J51 is an OEM replacement relay sequencer engineered for use in Lennox electric heating systems. Relay sequencers play a critical role in staged electric furnace operation — they stagger the activation of heating elements to prevent simultaneous power draw, protecting electrical circuits and extending the life of heating components.
Why Relay Sequencers Matter
In electric furnaces and air handlers, energizing all heating elements at once would create a massive inrush current that can trip breakers, damage wiring, and shorten component life. The 22J51 relay sequencer staggers element activation in a controlled sequence, ensuring smooth, efficient heat delivery and protecting your electrical system.
