Does a crack in a burn plate necessitate replacement? This is the rear burn plate on a Jotul 3cb. It’s a visible hairline crack about an inch or so long starting at the top. Some 10 years ago when I noticed the crack I removed the plate and the crack was not full depth and the plate was solid. It still looks the same as I’m cleaning for the end of the season. The burn plates aren’t expensive but can be a pain to replace. Opinions welcomed.
