Carrier 39-3SI Ignition Igniter
The ignition igniter in the 39-3SI has a main job of detonating the main heating fuel in your furnace. Your system will not get under way and heat up if it is unable to provide ignition.
Clues to watch for in a bad igniter
- There is no ignition of the LP or natural gas when the furnace kicks in
- System produces cold air throughout the house
