My guess is , no one has service experience with this, and I'd escalate your case with JennAir. You want to talk with a senior technical , service person or engineer. Chances are no appliance tech has seen this problem and they are likely to call in for guidance anyway. Better you find out now for free that a new display/controller is 700 bucks + labor instead of paying $95+ for a service visit to tell you the same thing. Perhaps JA will warranty the whole deal - but I wouldn't hold my breath. They've never been overly service oriented and now they have other masters that they are beholden to. This is more complex than 99.9% of fridge repair men can handle. It's more in the realm of the IT boffin or Home Integrator/ Stereo guy and even they will be put off that there is a refrigeration compressor attached to the "computer".

I bought the Jenn Air 42 inch French Door Refrigerator JF42NXFXDW for my complete kitchen renovation. We put custom cabinetry throughout and added the custom panels to the refrigerator as well as other appliances. I wanted the refrigerator to be built-in with the cabinetry fully integrated so that you weren't able to tell there was a refrigerator there. That has not happened. The hinge is definitely a flush mount hinge. You read correctly. The Jenn Air has a flush mount hinge. You need to know that the Kitchen Aid Refrigerator does NOT have a flush mount hinge. (though Jenn Air and Kitchen Aid are owned by the same company). They LOOK like the same refrigerator, but the hinge assembly is different. Problem: After going round and round with my contractor, we determined that the online specs for the Jenn Air panels are incorrect. The panels don't cover the hinge and are about 3/4" too short. So you submit the specs to your custom cabinetry company, they make them to Jen Air specs only to find that the custom panels aren't wide enough to cover the hinges. At that point, unless you Redo your custom panels (expensive proposition) there is no way can they be fully integrated into your cabinetry. The Kitchen Aid 27" warming drawer specs are incorrect as well. I am currently in conversation with Jenn Air (Whirlpool Corp). We'll see where this goes.

We are making the same decision right now -- either sub zero or thermador for a 36" French Door. I'm leaning towards Thermador based on (i) price (cheaper to start, then factor in the free range hood and it beats the sub by a $3k or more); and (ii) some aesthetic aspects, like the integrated look, the LED column style lighting, and that it would match a touch better with a Thermador range (which includes a free dishwasher). Based on name along, and my support of American manufactured products, I wanted the sub, but it's really hard to justify the extra money, particularly when I already have a hard time justifying the extra spend over the price of a Samsung FD which worked just fine for me for 5 years. But I would love to hear if anyone has any other thoughts. When is the Sub Zero 42 inch French Door coming out? I see it in the design guide, so I assume sometime this year.

I've been using mine for a month or so now. I haven't noticed any big problem. It is as described above. In theory things could fall around the edges, but not an issue so far. What has occurred is that when pulling out the upper shelf in the freezer, which includes the ice tray, sometimes an ice cube gets knocked out. It then falls around the back and bounces out on the floor. But it hasn't been a big deal. I wouldn't lose sleep over it. I wasn't especially happy with any of the frig choices that seemed workable for my situation. But I have fairly happy with the JennAir so far - moreso than I expected to be.
