I have an oven similar to the G3 that I bought from Amazon for $99. My problem with it is the bottom of the crust gets done before the top. I put the pie plate behind the top heating element and that helped a little.
I live in Mexico and don't speak Spanish , so it's sometimes hard to get things done.
This week , I found a small appliance repair shop and had them rewire my heating elements.
The top element stays on all the time and the bottom element is on the temp control. They made a mistake and have the red light connected to the top element, which is of course on all the time.
I cannot tell if and when the bottom element turns on.
I made a Pizza tonight with the temp control turned all the way down. The bottom needed more heat.
I'm taking it back Monday and have the light wired to the bottom element, so I can have more control.
The good thing is, here in Mexico, they only charged $15 for the wiring change.
