Wicked annoying

[Oink Oink]

Wicked annoying clinging sound coming from my stove as it winds down. Is this a normal sound that I need to just deal with? You won't see much in the video, you'll just hear the sound.

I couldn't hear anything but I'm almost deaf Is the sound coming as the room (convection) blower shuts off?? What do you mean by 'winds down'?

 

[PJPellet]

It sounds like the flapper on the OAK intake clanging. My P43 makes that noise but only when the wind blows hard and the stove is off. Hmmmm.

 

[Oink Oink]

When the flame is out and only the combustion blower is running.

x2 on the OAK flapper. See if the noise is coming from that area.

I believe that it is this flapper. I do not have a OAK installed though.

Well, I believe (I may be wrong) that the combustion air is still drawn in from the OAK connects, therefore the flapper is still in use. Have you cleaned the exhaust piping (careful of the ESP), including the pass thru pipe from just behind the ash pan to the exhaust connection? Maybe an partial obstruction causing this on shutdown?
Or maybe just wind blowing in the exhaust just the right way?

I have burned a total of maybe 5 bags last year (bought the stove at the end of the season.) I did however clean the exhaust pipe including the pass thru pipe. I don't think it is wind blowing in the exhaust, its a nice calm day out. My next thought is maybe because my house is pretty air tight that the stove isn't getting enough air and making the flapper go.

Thank for all your help so far with the suggestions.

"My next thought is maybe because my house is pretty air tight that the stove isn't getting enough air and making the flapper go."

That is a good thought. I can't think of what else would cause that, especially if the exhaust is clean and unobstructed. Keep us posted.

I get something similar on my Whitfield
it happens sometimes during burning
I sure wish someone knows what it is

Some stlves make a clinking noise when heating up or cooling down. The expansion and contraction of the steel. That sounds to be a bit much for what I just said. But its possible. My woodstove sounds like that when its getting up to temp.

The flapper sounds like a better idea. If in fact it is, you should be able to narrow it down the next time it shuts off. If you dont have an OAK. You should be able to find out rather quickly.

Sounded more like a "clanging" than a "clinging" sound. I had 3 wives that made really annoying "clinging" sounds on their way to the land of X-dom, so I should know. But, yeah I hear something "clangy", I'd guess a slightly out of balance fan, or something loose in the fan assembly.

 

[Oink Oink]

I took the panel off and actually watched the flapper make the noise. Now the question is why it does that?

There is a clear tube near that oak opening on the back of the stove. It goes into a "port" right next to the oak opening. Is there anything in that hose? Pellet chunks, pieces, etc. Racking my brain on this one. There are two tubes back there, I am referring to the bigger of the two, hope that makes sense.

Just thought of something else. Since you have no oak hooked up, when you hear the flapper noise see if something somewhere in your house just kicked in; like a bathroom vent fan, range hood, clothes dryer. Something like that. I betcha if the oak was hooked up it wouldn't make that noise anymore. IMHO. The pellet stove would be on it's own little pressure system independent of the interior of your house.

 

[heat seeker]

Excellent point about the pressure! It could also just be the wind shifting direction, a door opening, etc.

Shut the stove off and get it to start the process for it to make the flapper clink. Then open a door or window and see if it quits. That will rule out or confirm the starving for air theory.

Tried opening a window last night and it still was clanking. There goes that idea right out the window. Anyone else have any thoughts? I'm going to call the guy I bought it from soon, but don't want to sound like an idiot when I call.

You might want to find out if a Harman pulses the combustion blower during shut down to loosen crud and then expel it out the vent or out of the burn pot. That could cause the flapper to flap around a bit.

How do I find that out? Read through the manual a ton of times and checked out thier website. Any Harman owners out there know?

I don't believe so. This is the first I have heard of the flapper clanging so I am quite interested. Did you ever check out the clear tube I mentioned in a previous post? Just something else to look at.....

Guess we're not figuring this one out.

 

[MacSierra]

Sounds like the normal noisy ball bearing combustion and convection motors..

 

[staplebox]

Sounds like Morse Code. Your stove is telling you something.
