We do not suggest covering the sheet pan or crumb tray in aluminum file as this may cause the unit to over heat.
Sorry, there was a problem. Please try again later.We put foil on the rack level 3 to warm up cheese/bread sticks. We only make the foil (platter) big enough to hold the items we are cooking as to not completely cover the grate or get any foil in the circulating fan in the rear. It seems to work great that way,.
Sorry, there was a problem. Please try again later.It can cause uneven heating, food contamination if heat is too high... most ovens, toaster ovens, etc. do not recommend using foil.
