I purchased my Jenn Air oven (model W30400P) in 2002. From the very beginning the door would not close properly. I called for service early in 2003; the technician said this was "normal" and that the problem would resolve itself over time. Well, it did not.
Over the past few years the numbers on the "clock" became dimmer, so that I no longer could see the temperature. However, the oven itself was working (getting up to temperature) until a couple of months ago, when the control unit fried and the top element stopped working. I had a tech come out again; he told me I needed a new clock, a new controller, a new seal, and new hinges on the doors, and that all the non-hinge problems were due to the oven not closing properly. The total charges would be $1300. Since then I've also discovered the keypad isn't working properly.
I purchased all the parts and fixed it myself for $600; still waiting for the control unit, though. The new hinges DID NOT fix the door problem; they are exactly the same as the old hinges, which tells me it was a design flaw from the very beginning.
I'm angry with Jenn Air. It is excusable for a product to not work if they company fixes it, but is in inexcusable for a company to lie about a problem like this and cause numerous repairs down the road for the customer. Even now the door will not properly close, so I have purchased magnets to install at the top of the door.
