WOW! That's something!! I had that happen to a glass oven door one time..Hadn't used the oven that day at all.. Late one night it just shattered. Oddest thing I ever saw... I know you were just as stunned as I was... wondering what they heck happened?

Great that parts are covered and you got someone willing to do the work for you.. How about a homecooked meal if he don't want any pay for the job? If he is single, he would loooove a good homecooked meal.
