My Breville started making loud noise, and we finally had to stop using it. In researching on line it is a fan weakness in the unit. I also got mine from QVC. I don't know if they ever corrected their design flaw.
I purchased an Emeril model that had many of the same features as the Breville. I don't like it. I don't like how it toasts, and the inside area seems a bit smaller. It has the same footprint on my countertop as the Breville.
Bed Bath and Beyond has three models of the Breville, Amazon carries it too.
If you find a good replacement, please post as I would be interested. Good luck.
