My stove has been having an issue where it will run for a while with no problems then start feeding pellets like crazy then shutting down and not restarting. Everyone here is saying that it's probably a door gasket / vacuum issue. I've told my dealer about the door gasket and what you all have said in regards to the dollar test. He keeps saying that it shouldn't have anything to do with the gasket. I called Heatilator yesterday and they are now saying it's a control box issue or a vacuum issue. How do I go about telling him to fix the gasket on the door without sounding rude?
