The only thing I could find for your model,& # was just parts..
I have a combo to but mine is the Daewoo brand.
It's technical.Right down to the cooking power lvls,and convection oven temps.
Did yours come with any accessories for cooking? If so what did it come with? Got a picture?
With mine to grill/convection cook anything it's a must to have a rack and oven safe dishes to use with it.
Anything cooked either way has to be off the turntable.That allows the heat to be distributed evenly.Preheating for a few minutes is usually a good idea.
If you could give us a little more info about your model.Even the little details.I'm sure people here will help you as much as possible.
If your with me that's great. If not. Get out of my way.
