Many Lennox furnaces have ignition controls that are manufactured for Lennox by Honeywell, Johnson, Robertshaw, White-Rodgers Ram, HeatCraft, or Fenwal. As some models of ignition controls become obsolete, or the technology is replaced with a newer control, Lennox will update the specified replacement control. If you need help use this form to contact one of our parts specialists to help you locate the latest part for your furnace..

Safety note: When a furnace requires an updated control, many times the control wiring of the furnace will need to be changed. The safe installation of an ignition control requires that you understand the theory of operation of the furnace and be able to read and understand the control circuit schematic. If you do not possess these skills, you should have your control replaced by a qualified servicer.
