How to remove broken light protector/cover from inside oven?
Good news - it came off!

A Hot air gun was useless as was a butane torch - I suspect the heat was not softening anything and the adhesives were well and truely burned on.  Perhaps spraying cold water on the hot glass might have helped crack it, but read on.

In the end I used a teatowel in one hand to cup the entire fitting and then pushed an "automatic punch" against the lip, and one piece cracked out on the first try.  Against the other side, it took a dozen hits before breaking the same way, with a vertical crack and a chunk out.



I left the lamp in place to protect the socket from any damage.  Its already got oil burned on the glass.

So then I could simply unscrew the remainder and it fell out in two pieces after one rotation, which I caught in the teatowel.

Not sure if it was the increased grip, or if it was the shock which broke the hold but it turned freely after that.



Despite using a damp catching cloth, there were heaps of tiny glass shards in the bottom of the oven.   Had I attempted to use heat and cold to crack the glass, it could have made a bigger mess.



Careful cleanup is required here - glass fragments are no fun near food.
