Product review (5 stars): A Great Range, but with a Learning Curve
We installed this range when we remodeled our kitchen 2 1/2 years ago and have used it extensively since then, and have come to love it.  Here is what we've learned about it: You better have a GOOD technician to set it up properly and CAREFULLY adjust everything so that all the burners work correctly. BUT once set correctly, all burners have kept their adjustments and we've had no problems.  We have the model with gas burners on top, gas main oven and electric bottom oven.

There is some kind of a vent fan that comes on in the oven at around 375 degrees, or above, and stays on until the oven cools back down, and it blows hot air out the slots at the BACK of the top.  This hot air is hot enough that it cracked the grout between the metallic ceramic tiles of our backsplash and we had to replace the grout with colored silicone.  But the original grout job wasn't done right, and the silicone looks better anyway, soooo, no problem.  However, my wife used to be annoyed by the noise of the fan, but she's gotten used to it.  It isn't loud enough that it ever bothered me, but it is noticeable.

We've seen in some reviews where folks complained about the noise of the fan when cooking in convection mode.  The convection fan is much quieter than the vent fan mentioned in the previous paragraph. In fact, it's almost inaudible, BUT we don't use the convection mode when baking above 375 degrees, so I don't know if the convection fan gets louder above 375.  BTW, the Convection Roast with Probe is a fantastic way of cooking meats.  It has always turned out perfect, without fail, but we've been careful to get the probe properly inserted into the meat.

We've seen complaints in reviews about the front knobs and panel getting hot while using the oven.  We've NOT had that problem at all, ever.  I believe there must be a setup problem with the ranges that are having that problem.  I also wonder if that's a problem with the electric main ovens and not the gas ovens.

The bottom oven has a 120 volt element in it rather than the 240 volt elements that normal electric ovens have, but it still cooks perfectly, HOWEVER, you have to allow for a little extra time for pre-heat, but it's not a huge amount of extra time since the bottom oven is not as large as the top one.

When you go to cook pancakes on the griddle, because of the mass of the griddle, you have to allow it plenty of time to get good and hot.  I drop a couple droplets of water on it and don't put the batter on it until the droplets sizzle good.  You have to keep the burner wide open on high the entire time you're using the griddle to cook effectively.  But it DOES cook well, once it's hot and kept hot.

We really like the heat ranges of the burners.  The power burners heat and bring things to a boil quickly, but turn down to simmer very nicely.  The simmer burner on the back right is terrific for warming and slow cooking.

All in all, we love this range.  The owner's manual could be more clearly written, but the info in it is correct, unlike the one for the last gas range we owned before this one.  We highly recommend this range and would buy it again.
