On the second day of operation, my fan started making a rattling noise like something is loose. Ugh! Anyone know on the PE Neo 2.5, if you have to pull the stove to get at it? The installer is supposed to come back and make adjustments or whatever, but it's the weekend and I don't want to wait if I can get at it without removal. It makes noise at all speeds, but I can find some quiet spots as the stove cools down. As the unit heats up, the rattle gets worse. Heres a short video.
