Assuming that your refrigerator does have flame outage detection then adding the appropriate components to provide a LED indicator should be fairly simple although carrying out the modification yourself might be frowned upon

It is positively illegal.

The OP wants only to be able to see if the flame is on without using the inaccessible viewing window. He's told us that there IS a flame-failure device (without realising what it was).
