The front door handle of our Technika Bellisimo oven, Model TB70F has fallen off. The front door of the oven has now separated into 2 parts as the screws and bracket holding the handle on to the front of the door also holds the 2 door parts together. How do I reassemble it? If I put the 2 door parts back together with the handle and the brackets, there is no access to do the screws up?
