Casa2G80 oven repair help

[mh88]

Hello, I have an 8 year old Casa2G80 built in Oyster Bay, NY 11771. I had a friend build it way back when and there is quite a bit of cracking in the dome and on the front around the door. I have a feeling, but an not sure that the temperature inside, especially the floor, is less hot and more volatile I was wondering how to address these issues and whether I should attempt to repair the existing cracks. I hope to find someone local to check it out and advise/repair. Please let me know if anyone has ideas. Thanks-M

There is no way to successfully repair the cracking and it should not cause any performance issues if not too severe.(large wide cracks). Is the oven exposed to the rain? Moisture can impact performance considerably.
