We have a 2 year old natural gas furnace that is making a noise during operation that sounds like a muffled cabinet door being shut from halfway open. It makes this noise every 30 to 45 seconds while it is firing. Once the blower shuts off the noise goes away.
Is this normal or does it need to be checked out? Outside of this noise it is extremely quiet.
