Is Your Furnace Electronic Ignition Out Cold?

Furnace ignition problems and solutions vary according to the type of furnace ignition system you have. Not all furnace pilot light ignition problems relate to a standing pilot in your furnace as I describe in How to Light a Gas Furnace Pilot.

Most all modern furnaces use an electronic ignition system having either an intermittent pilot or hot surface ignition.

Modern electronic ignition systems are more reliable than the standing pilot systems of old, but just as your new car has an electronic brain, so do some of these furnaces. And that means you're somewhat limited as to what can be done "under the hood" when they don't work

But take a read of the tutorial Overview and Repair of the Electronic Ignition Furnace and you'll learn how they work, and what you can do when they don't.
