My oven works fine in general. However, when I try to set u the control knob for themperwture or time change, the value only decreases no matter which way I turn the knob. So for example when I want to bake and the default temperature of 350°F appears, I can only decrease the temperature no matter which way I turn the knob. Yes the temperature decreases even if I turn the knob to increase. The same behavior is shown when I want to set the time. I can only go back and not forward no matter which way I turn the knob. Does anyone have an idea what the problem might be and which part might need to be replaced?
