Anyone else get a super loud fan buzz from the rear of unit. If I smack the oven it will subside but I feel like a Neanderthal. Bad noise smack go away…

Any one else have this issue. Possible causes? Possible fixes aside from playing prodigy smack my bitch up and going to town on the oven.

I have the same issue. Started several weeks after getting the unit. Opening and closing the door seems to be the little jolt the unit needs to stop it from buzzing. I have emailed support.
