HEALTH HAZARD ! Please check your oven no matter what brand. Had a new-to-me Frigidaire oven installed - model # CMEF212ES2. Only lightly used. Turned on oven and while pizza was baking noticed 2 large fiberglass tufts inside oven. One was sucked down into bottom drawer as I watched thru glass. Took out drawer and looked up towards bottom sides of stove. ALL along the bottom sides of the stove, matts of fiberglass hanging down and easily viewed. As stove heats, air current sucks up air from this area into drawer and then into stove! This is possible because seal around door that leads to drawer is not tight. Able to stick butter knife right up into the stove when door is closed. It seems to me that this fiberglass should be sealed in and not open. PLEASE check your stove no matter what brand oven you own ! I am reporting this to Health Canada product safety unit.
