I was doing my stove cleaning and when I removed the oval plate on top I found a crack that goes about 2 inches into the top. When cleaning to attempt a repair I found another one that almost crosses it at a T. Never overfired or mishandled in any way. 9 year old stove. Has there been any reports of these stoves having some casting problems? Crack starts right where the screw hold down is underneath. Never overtightened because I removed the screws when I first got the stove. Been burning would for 40 years and have never had this happened before. Thinking on drilling to stop the crack and patching for this season. New top is pretty expensive.

Heard of some cracks in the base . . . often tied into folks who were burning with the ash pan door open resulting in a forge like situation. I do believe this is the first I've heard of a crack at the top. What does the baffle and insulation look like?

Everything looks fine. I was on this forum when I first got this stove. Actually learned a lot from reading your posts. I gently vacuum insulation every year with a small tube shoved into my vacuum hose. No rips or rough spots. I don’t do ash pan fire ups either.

Cracks on the top are not that common. Look for possible air leaks at the top of the door gasket and/or in the stove top gasket near the cracks.
I think the warranty is 5 yrs for the cast iron parts.

Yes, drill a small hole at the end of the crack and examine the stove top gasket for leakage in that area. I would also consider pushing in some high-temp epoxy into both sides of the crack after cleaning it out.

If the top is cracked, then most likely the bottom is to. You should repair the stove by replacing with the correct factory replacement parts.

Jb weld will not hold, because it will expand at a different rate than the cast, which will just open the crack up again.

Thanks , I ordered a new top from rocky mountain stove company for $365 , figured the jb weld wouldn't hold up for that reason .
