I have friends who remodeled nine years ago and bought a Jenn Air white slide-in gas range. At that time, the choices in non-commercial, slide in gas convection ranges were pretty much limited to Dacor, KA, and JennAir. (GE and Frigidaire made gas convection free-standing ranges, but their gas slide-ins at the time did not offer convection). She <span style="text-decoration: underline;">HATES</span> it and always wishes she'd bought KA or other brand (her kitchen uses medium tone wood cabinets and white appliances, and she's happy with white color, but hates her JennAir). I've never noticed any culinary disasters at their house, but....
1. She says the cooktop (deeply recessed/sealed) and grates are very hard to keep clean.
2. The range has had two recalls and has required three repairs in nine years.
3. The oven door has never fit or closed securely, so that her baking times take LONGER in spite of having bought the convection model. This also means that she cannot effectively use the self-clean feature.
4. The range also had a dehydrate function (I assume it was low temp convection) which never worked properly.
All in all, she felt it was terrible value for a $2000 price tag. She had a gas line and 120V behind the range and was not willing to rip out the wall to install 240V, hence no electric or dual-fuel range. She preferred a gas cooktop to electric at that time, but now would like an induction cooktop, which needs 220V.
In contrast, I have a late 2001 Frigidaire gas convection range which works perfectly. Grates/cooktop easy to clean, big oven, and convection, cost $700 at that time. My only complaint is that grates don't go all the way across; they did offer a full grate model, but the design at the time looked cheesy, and it still only offered four burners, same power as mine. My burners are 12K, 2 x 9K, and 5K. By today's standards, a 12K "high output" burner is rather anemic, but in 2001, 12K was the definition of "high output" in a non-commercial range.
My model has been replaced by a five burner unit with grates that go all the way across the cooktop. One burner is very high output (16-18K BTU), one is high output (12-14 BTU), two are normal, one is 5K simmer. The porcelain grates are dishwasher-safe (per the Frigidaire manual) and easy to keep clean. Temperature stays constant. Oven warm-up is a little slow, but if you turn on the convection fan it speeds the process somewhat (example: for baking bread at 450 F, it can take 15-20 minutes to reach 450F from a cold start).
