I have a gas furnace that is about 10-11 years old that when trying to turn on, will go through a series of 6-7 "bang-psss, bang-psss..." before shutting off.

I assume this is the furnace trying to ignite, and I didn't want gas accumulating, so thought I'd look around before making a call.

I've no clue about this stuff, but sounds like a bad igniter? If so, is it something relatively easy to do?

I appreciate your time and consideration.
