On Consumer Affairs' website, many customers complain of glass doors that shatter with several users stating that the inside glass door exploded soon after beginning the self-cleaning process. Another user states that it's not possible to clean grease that builds up between the two glass panes in the door. Others complain of doors that either won't seal properly or that completely fall off.
A number of users express issues related to faulty control panels including ovens that turn on or off by themselves or panels that show the oven to be off when it's still operating. Many reviewers had trouble with maintaining temperature control while cooking.
