Long story short:I broke my main oven door glass.When ordering the glass I noticed where it said will also need this-moisture barrier.It's just a strip of some kind of foam like weather stripping with a self adhesive.It's 18"long.an inch wide and a half inch thick.I have a feeling it's some kind of retro fit thing because I'm sure I see it in the midst of the shattered glass.So does anybody know where the darn thing goes?Thank you in advance.BTW,glad I found your forum!
