Well, the shoulder season is still here, 65* yesterday and I needed to do something constructive rather then look at a cold stove and JETS football. So, I performed the dollar bill test on the old 2 door castine. Each door was tested with the bill in 4 differnt locations. Only 1 of the 8 areas was a little less the very tight. With this in mind I guess I won't replace door gaskets until maybe next fall. Not wanting to JINX myself but I haven't had to make any repairs on this stove since I purchased it in 2001. Any thoughts as to how long gaskets usually last before needed replacements? Thanks for any info.
