We have a broad inventory of circuit boards that are used across the Lennox
product line. Today's modern furnaces usually have an integrated ignition
control that serves as the "heart" of the furnace. Integrated controls have the
ignition system, safeties and blower controls all built into one control. Heat
pumps and condensing units also use electronic devices in their controls. If you
know the part number of the control you need, simply use the parts search to
locate a replacement. If you need help, make sure you have your Lennox model
number and send your information to us using
this form.
One of our parts specialists will help you find the correct replacement.
