Man that does not surprise me, I am taking mine back tomorrow. I hope you can get yours returned somehow and be done with it. Don't tell me that they can't send out a known good board the first time. Are they pulling these boards off of returned stoves and hope that one works or what? Their has to be more people out there that are having the same problem than vrosario63 and myself. Their is no way this is isolated to just a few people. The company admitted to me that they had a known bad batch of boards, so where are some of these people. Something smells fishy here that their is not more posts on this issue. The bad / dangerous thing is that their may be people out their that are operating their stoves like this and don't know any better. I did read a post, but i don't remember where, that their stove would clog up with soot when they ran it over feed rate one. The combustion blower completely shutting off at any feed rate is not normal for this stove. If HHT keeps this up, people could be burning their houses down if the owner doesn't realize their is a problem. Seriously, HHT customer service told me after my 2 hour ordeal with them that I quote "sounds like your stove is running normal". I had it running on feed 4 at their request, and the combustion blower kept turning on and off about every 3-4 seconds. The entire combustion chamber was a complete sooty mess within minutes.Well of cause as expected the new board did not work...Not only did it not work but it was worse than the others....When I first plug it in the ignite when on and nothing else. I then unplug it and tried to start it but as I pushed the start button it would not respond. I pulled the board only to find that there were 2 screws missing, these screws hold the board to the face panel. I pulled 2 screws from the other board and installed them. I then reinstalled the board in the stove. I hit the start button and it started as normal. After it completed it's start cycle I then push the feed rate button to bring it up to 3 and guess what it failed....Same issue as before and that now makes 3 board that do not work...What part do they not understand that these boards are not working from the manufacturer it self...I reinstalled my control board from the older Pelpro Bayview and presto...it works...I don't know what else to do but they are going to have to fix this one way or another.....
