The mica window in meller ovens was old, ugly and hat a whole. It affects the draught of the wohle thing. So it have to be replaced. Getting old replacements for ovens can be a pain. Maybe you have to google little longer, or order overseas.
Step 1: Loosen the Screws
After thoroughly lubricate with MOS ², the screws can be loosened carefully
Step 2: Old Seal and Mica Window
The seal and the mica window are no longer continue using and can later be discarded. Next, we need to make a new gasket from a Feuerfetsenplatte and of course get a mica window. For now, we keep the parts to compare!
Step 3: Making New Seal
With the help of the metal frame on the new seal sketch out, and cut it with a knife hobbyists. Taking care to seal the frame should not be too thick, and can break easily!
Step 4: Cut Mica Window
Best to cut the mica window with scissors
Step 5: Trick With the Adhesive
The trick is not to get mad when installing is all three parts in the correct order - Gasket, mica window frame and metal adhesive glue together with a normal household. Thus, the net screws slip nothing more.
Step 6: At the Conclusion
I had to also flex a few longer screws yet. The originals were too short with the new seal. But you must not be too long. The thread in the oven door is not very deep. I still recommend the screws so well greased at the next repair is a good chance all aufzubekommen again.
