I also had the door of this oven explode on me, simply by opening it. Just thought I’d drop by and let you know. Any more leads on this ‘QA’ brand would be appriciated, as the oven came (rented) with the house.
If its not around the door surround, it will most likely be on the roof of the oven box. It will need sliding forward to view. Don’t forget to refit the security screws afterwards.
