My Harman Accentra stove has been making this noise more and more frequently. I wonder what is causing it and if it's a part I could replace myself. It's from 2011 and I know a couple of parts were replaced a few years ago, but I don't know which ones.

Any thoughts?

Well, you have a choice it is either the combustion fan or the
convection fan. Does the noise start as soon as you start the
stove or when the room air heat fan starts ( convection fan)?
Yes if you are the least bit handy you can replace either unit

Thanks for your reply! It makes that noise as soon as I turn the stove on. So that means combustion fan, right? If there is a YouTube video that shows how to do it, I should be able to handle it.

Would it be this part?

yes,, the exhaust motor is 1st to come on.. dist blower doesn't come on for quite a while..
when ordering make sure to also get new fan blade in case the original gets damaged in the removal.
pellet stove parts for less is great company.. changed mine this past summer..
not hard at all. might have to sawzaw the blade shaft[ from inside] as it has a set screw to hold it on that may be too frozen to loosen as to remove it. if not sure call them with model number..pix looks identical to most harman's..

btw: the second one has the 3 wires attached so will be easier to replace.... no re- splicing or making new connecting etc..
I imagine the one without wires is cheaper but both are same motor..

also, you can snap off the blades 1st as it will make it easier to cut the shaft after if cannot loosen set screw...[ reason to buy new blade .]

There are a couple of YouTube videos
from quick to a long step-by-step video
It's a little work but not overly difficult.
