Sequel. Bro's wife's boss found her technician certified by Ontario to inspect Frigidaire range yesterday. He found nothing wrong – he opened display panel on cook top, tested electricity, and no electricity leaked. He said he saw no evidence the oven turned itself on to bake – he said he believes customers, but not this time. He said not worry about smoky smell. He charged $200 CAD, but he offered return for free if still issue.
After technician she never used range and opened open door to air out smokyness. Oven has always been empty. But today oven smells smoky again. The oven hasn't turned itself on again.
Anyone know why oven smells smoky when empty?
Smart for her to pay a second opinion – a different technician?
