Lennox 12Y80 Sequencer L99H008 Optimized Ignition Reach: The 1The Lennox 12Y80 Sequencer (OEM part number 104284 03) is a critical thermal sequencer relay used to manage staged heating in Lennox electric furnaces and air handlers. As a DPDT normally open component, it acts as a timing controller for 24V circuits, ensuring that heating elements and blower motors activate in a staggered sequence. This staged operation is vital for preventing massive inrush current and potential electrical overload on the job site.
