Loud buzzing fan

When heating and cooking the oven makes a loud buzzing fan noise When I give the oven a light smack in the rear it stops but I can’t imagine a good smack a la 50s television sets is protocol. Anyone else experiencing this.

I’ve had the oven just over a day now and experiencing a host of irregularities that I’ll share as I find if they are one offs or continual problems.

Glad for this community


No buzzing here.
