The dealer installed my stove and they put two small metal plates under the center of the stove (under the air control) to level the stove front to back. I noticed two right angle plates just under each fan that are welded to the stove. I am wondering if these should have been used to level the stove instead of under the air control. The reason I ask is I have been having a terrible rattling noise whenever the fans are on. The noise changes as the stove heats up and cools down. The rattling isn't from the surround it's coming from the plates that secure the fans and from the metal that directs the air flow from the fans. I haven't heard of anyone else with noise issue like I have on this forum. I have a call into the dealer but I can't stop poking around while I wait on them.
