Harman accentra feeds only on slow

[smirnov3]

Hey, I have a question.

I just turned my stove on for the first time this fall, and I am having some weirdness

My accentra insert feeds fine when I set the temperature low (ie small flame), but when I turn it up, the stove operates normally for 15 minutes or so, and then stops feeding pellets. The feed light goes on, but the auger doesn't move.

the stove (and flue) were cleaned in the spring. The door seals are tight (I checked).

any clues as to what this could be?

Check your flue again. If the stove can't breath it won't feed itself anymore fuel than what the high limit is of the ESP. The feed light coming on without any feed of the auger is alarming. Did you leave any pellets in the stove last spring?

Yes, a handful of pellets got left behind in the stove last spring.

>. If the stove can't breath it won't feed itself anymore fuel than what the high limit is of the ESP

I don't understand what you mean by this.

The feed light coming on without any feeding happens if the flue is blocked with ash, but 1) I cleaned it and b) the fire is dancing quickly, flickering form side to side like it should (no slow waving)

Exhaust temp gets high and stove will reduce the feed

I think I may have solved the problem - the lid on the fines box was loose. it was letting in air, so that the combustion blower wasn't able to pull a vacuum across the flow gauge / pressure meter (whatever it's called)

That will do it.

That will do it.

Yep. Was gonna say a permissive was not being satisfied but you all beat me to it.
