My top rack falls down if I get more than 5lbs on it

Their has been issues on certain models of Jenn-Air ranges where the interior cavity was an issue. You should be able to have up to 25 lbs. of down pressure on the rack with the rack completely extended in the out position. Their is a repair kit for this issue and I recommend you call Whirlpool at 1-866-698-2538 . They will be able to provide you with the detailed warranty information.
