Anyone have an idea what might cause this? I'm on year two of my XXV and have never seen anything like that, and hope I don't.
noone seems to know for sure......it's rare, doesnt happen to everyone with a certain model, and no common denominator has ever been found to indicate a certain issue.....
The gummy stove in the feeder mechanism has to do with burn back or deposit from unburnt gases. Have you cleaned out the fine box? If you have excessive fine in the feeder tube where the auger is and are running a very hot stove you can get residual burn back (slow burn) back towards the feeder assembly. Likewise, running the stove for extended periods on low settings can lead to gas deposits. Very tough to fix once it has set in and it gets worse...then stops feeding. The entire feeder assembly needs to be removed from the stove and dipped into hot water to dissolve the creosote resin, then put back together. About a 12 hr job if you know what you are doing. I've done it over a two day period as everything needs to dry. Essentially the entire stove needs to be unassembled, cleaned and reassembled. Additionally, there is a modification with an air tube which can be added to help with the unburnt gases but the mod will void the warranty. The stove may be covered under warranty if it is less than 5 years old. If you are anywhere in southern New England I'd be happy to look at it for you while I'm on the road.
I dont agree with all of this. First of all, the addition of the air tube DOES NOT void the warrantee if done correctly, in fact, its sanctioned by Harman.
I agree it takes quite alot of time to "fix" the gummy issue....not 12 hours, bbut certain stoves are easier than others....the "P" series is easier than the Accentra and XXV's, and it really isnt a job I would want to do in a customer's home....VERY messy. You can either do what smwilliamson says, remove and clean the mechanism, or, you can replace the feeder weldment...we've done both. If you opt to clean it, its quite messy and alot of work, whereas, if you replace the weldment, its somewhat messy and alot of work...yuck
