Unfortunately, I must agree with MOSFET. We've had a DCS 30" dual-fuel range for eight years and it has been a total lemon. I have loved it while it has worked, but it has needed so many repairs that I could have bought a new stove by now. First, the cooktop rusted out underneath, even though I followed the cleaning instructions in the manual. Fisher-Paykel (the new owners) finally fixed it for free, after a pretty big tussle. Now, the oven has gone kaput, even with three service visits.
Ironically, Fisher-Paykel is offering me a break on a new version of my stove, and I'm actually thinking about it because it looks like they've put a lot of work into redesigning the whole line. But, once burned...
