Noisy fan

[frolingdual]

My fan used to be nearly silent but now it's vibrating when at high speed.

I have noticed the flue discoloured which looks like it got really hot. So I'm wondering if it got too hot and distorted the fan.

It only makes a noise on start up then the speed reduces and it's nearly silent again.

Any thoughts on how to solve?

If I need a new fan does anyone know of an online store I can buy one?

First thing we need to know is what make and model of stove ?

Cool - burns pellets or wood! Sorry, I don't know anything about that unit, but hopefully someone can come along and help you out.

Never heard of that stove here on this side of the pond. I would first try and clean the fan before attempting to buy a fan. Oven cleaner or orange cleaner. Does not take much buildup to cause an imbalance and high speed will amplify the problem.
Good luck

Thinking about it that would make sense as I did have a poor burn just before it started. I will give it a try. Thanks for your help.

Interesting burner.
Other than the fan, How do like it?
Do you burn both wood and pellets?
How does it work?

Everytime I think my fan is vibrating, it turns out to be a back side panel or similar touching my Dist fan housing. Always on Startup for a minute or 2..

you fill it with logs and forget it. when the buffer temp falls it starts up on pellets. The pellets flame passes through the log chamber. As the logs light it will contribute to the flue gas temperature and reduce pellets until it's just running on logs.

If you don't put any logs in it just runs on pellets. It's very convenient as you can just load when you like.

BUT I have given up running on logs this winter due to dark smoke and tar build up causing the turbulators to get stuck. I think it's solvable as I get experience of loading and what I should burn. But did read something about forming an ember bed before loading being recommended. This clearly takes away its main benefit if really necessary.

Thank you I will have a look at this.

How long has the wood been seasoned? I have the luxury of steel bins to season my wood for 3 + years and almost no creosote in a old stove with clay liner.
