Description
The Lennox 31W67 is an OEM replacement relay sequencer engineered for use in Lennox electric furnace and air handler systems. Relay sequencers play a critical role in staged electric heating — they stagger the activation of individual heating elements to prevent simultaneous inrush current draw, protecting electrical circuits and extending equipment life.
How It Works
When a call for heat is initiated, the relay sequencer energizes each heating element in a timed, sequential order rather than all at once. This staged approach reduces peak electrical demand, minimizes tripped breakers, and delivers a smoother, more consistent heat output to the conditioned space.
