When temp. selector is set to Toaster On/Bake Off position and setting is set for toast (light/med/dark) nothing happens. The indicator light does not come on. Is there something else that needs to be done. It seems like there should be another step to "turn on" the toaster function. Just choosing the setting doesn't seem like that would turn the function on. I'm am following the manual, so it may be that the oven defective. We just purchused it yesterday.
