Actually, its the tech! We had our Mt. Vernon AE installed right before Christmas, and I have posted a few quirks I have experienced with it, especially the low hopper icon that has been on consistently since day 1. Other issues, such as misfire, min firepot temp, etc have been increasing in regularity. The tech has been to the house 3 times, the last in which he dropped the hopper door and scratch the &%*@ out of the door and the front of my stove. My wife heard him drop it from the other room and came to check up on him. At the end of his last visit (yesterday), we waited to see if he would "own up to it" and he did not. He even scratched the back black surround as well. Well, after he left, 10 minutes later (after the low hopper icon popped on again), we discovered even more scratches and damage, so we called the owner and explained to him what happened. At this point, we have accepted the fact that we have a lemon and have insisted we receive a new stove. After replacing the hopper sensor twice, a new control board and various other "maintenance" items, not to mention the multiple scatches on the exterior of the stove (certainly not performed by us considering what we paid for it - the kids have been told NOT to go near it!!) the owner has agreed, so now we wait for that to happen. Thanks for letting me vent.
