What is the difference between the set and real temperatures?
I don't have a hard measurement for this. What I can tell you is that in a timed test I ran with the oven set to 350 degrees, it was at 150 at the end of the preheat cycle. At the end of an hour, it was at 347 degrees and had stayed there for at least ten minutes.
How long takes to light up thee burner since you push the Start button?
I'd guess it's a minute or less.
Pull out the Broiler and watch the flame. How high is it?
Quarter inch? Half inch?
What is the color of the keypad? Black.
