Actually, don't mess with it until you verify it's status as if it's only 6 years old, it might still be under warranty:

If it's something like a hot surface ignitor, then bfd, those are cheap, the labor to have a tech install is going to be 4-5 times what the warranty part would cost you to buy outright and just install yourself, but a blower motor or worse, a circuit card, those are big dollar parts.
