My Accentra (freestanding model) is burning fine now. Earlier postings of feed/start up/flashing light problems seem to go back to the combustion motor. It was plugged enough with soot and ash to prevent it from starting. No combustion motor -- no feed -- no ignition, etc. But I still have some smoke in the hopper when the hopper is getting low. I've checked with two dealers about this and both have told me about a Harman factory authorized modification that should be done. It involves drilling a .25" hole in the feeder body housing. The slide plate cover is removed and the hole is drilled into the wall next to the auger. This is to fix some sort of backdraft/pressure problem. I quickly saw the service fax that Harman sent to the dealers regarding this fix. It should slow down pellet resin build up on the slide plate. New Accentras come through with this modification. If there is a number 2 engraved on the back of the feeder housing the stove is all set. My stove is a year old and does not have that number or the fix. Also, the outside air is contributing somewhat to the problem. The very cold outside air may condense and be part of the problem -- really not sure about that. So both dealers have techs to do the job -- depends which one is availble the earliest after the Holiday. And it's under the Warranty. Any one hear about this Harman mod?
