I noticed some cracks around the front door on my Englander NC30 recently. They are right at the top edges where the air wash plate ends on the interior of the stove. Not sure how to handle this. I'm not a welder, but perhaps they could be welded? if anyone else has run into a similar problem with an Englander I'd love to know how you handled it. The stove is about 5 years old at this point.
