Product review (1 stars): worst purchase ever!
I really regret that I didn't read reviews before purchasing this range.  This is a nice looking range and seemed like it would work well in our upscale apartment.  Here is my list of issues:
1.  The burners have a small high to low range.  Unless you dial back from high (manual does not recommend) you can only get it down to medium: absolutely no simmer.
2. It takes 20 seconds or more to get the oven to light and then takes a long time to get up to temperature.
3. I called Avanti for warranty service because one burner was sticking.  When I pushed it in to ignite, the igniter would not release: I would have to pull it out manually and sometimes the knob came off.  They tried to find a service company to come out but no one wanted the job.  Finally, one company told me that Avanti pays very little for warranty work and it takes them a long time to get paid.  After going back and forth for months, Avanti agreed to ship me a new range.
4. I received the new range and when I unpacked it, the top had a large dent on one side.  The impact was not visible on the outside of the carton but the impact was so much, it cracked the cast iron grate.  At this point, I took the top off the first range and put it on the replacement.
5. After having it installed (at my expense), the oven will light but not stay lit.  The broiler does not work at all.
6. Avanti, has NO technical service/support at all!
I am so sorry I wasted my money.  This has been the worst purchase I ever made.  By the way, I have an Avanti dishwasher and it is just fine but DO NOT buy a range from them!
