Ok, this is interesting. I called my dealer this morning and talked at length about what is going on. He called Harman and they told him that they think it's my burnpot. So they are sending him a new burnpot. My stove(P43) was manufactured in Feb. of 2011. They checked my stove's serial number and said it could be the burnpot they were using at that time. This is the first that my tech has heard of this burnpot issue too. So could this be another burnpot problem? I hope they aren't just throwing new parts at it. I am very interested to see if this fixes the problem. Plus I'll have a chance to learn more about my stove while the tech is replacing the burnpot. They hope to have the new burnpot to my dealer within the week. I am hoping. I can't see why the burnpot would cause this but I am not a Harman tech either, time will tell. I will keep this updated and let's all hope this takes care of it.
