Installed our Harman Absolute 63 last February and loved it. Heats all of our 2,000 square foot home. Recently I have noticed a clicking sound when the fire ramps up and then calms back down. Had the dealer come out and said it was normal metal expanding and contracting. I’m adamant that I have not heard this sound before. Anyone else experience this? Driving me nuts since it is in our living room and we have not heard it before.

My Absolute 63 does it as well when it's burning especially hot.
Good to know. Does it do it make the clicking when the flame is calming down after burning hot? Has it always made that noise for you? I feel like mine started that not too long ago but I also might not have been paying as close attention to it as I am now.

I'll try to pay attention but I believe so. I know the clicking happens a lot when I open the door after a good burn following a good clean.

Thanks! On another topic I saw that you said your feed rate is set to 6%. That seems low compared to the default of 65% I think it is. Does it help you burn less pellets?

I set my feed rate max to 45% due to poor pellet quality. I believe what you are referencing is an issue I have where once the room reaches the set temperature, the stove defaults to a 6% feed rate and continues to feed at 6% until I open a door to stop it, regardless of what temperature it may get to. Changing the feed rate limits doesn't really improve efficiency or reduce costs unless of course it results in a lower room temperature which is the same result if you had just reduced the room temp.

Gotcha thanks for the info! I haven’t experienced that yet.

I think the cast iron stoves seem to make more noise like that since they are bolted together. The Pseries are plate steel welded together.

For 12 bucks you can replace it with a new one from NAPA.

It’s strange to me that I didn’t notice it last season or earlier this season? Is this something that develops after the stove is no longer new?

It can also happen right from the beginning. It depends entirely on the stove and how it's been treated. It's entirely possible, though, that this year's pellets are burning hotter, so you're hearing expansion that you didn't hear before.

Or, if you're like me, it's always been happening, and you just noticed for the first time. Like the time I heard this strange ticking sound in my bedroom and traced it to the radiator as it heated. I'm sure it didn't do that the first winter we were in the house! :)

Metal heats, it expands, cools, contracts. Been that way since the beginning of the metals age.
