My loss is your win... Our glass element broke and is not replaceable through breville so we are parting out the unit for people who need parts that breville wont make good on or are no longer making.  Our breville isn't that old but we know people would rather replace the  part rather then scrap the whole machine because they  really are nice ovens/ toaster/ air fryer and are quite pricey brand new.  We weren't as lucky to be able to find the replacement part.  We will be listing all of the parts reasonably so please check out our other listings for parts that you may need.  This part is a hard to find part  the feet for the unit.   Model A2BUAOVA211819043.  The lot comes with the 4 rubber gasket metal feet inserts as well as the plastic vented covers for the bottom of the unit.
