As you can see from the attached photo GE would not allow my review on their website as it would "direct business away" well that was the point. I was trying to save someone else the headache and trouble I've been dealing with. The registration card and online registration only ask for date of installation, however when it came to replacing my faulty unit they would not do it until I provided proof of purchase. We purchased prior to our kitchen remodel and by the time it was installed it was over a year from date of purchase. So now they don't want to replace it and one oven doesn't heat properly.
