Customer reported that she noticed recently that the grill have been coming on when she uses the convection setting to make her casserole.
I checked it, the outer grill element glowed, the middle grill element doesn’t appear to be active on this setting. The base element is working. I checked the temperature and it is maintaining temperature.
I am at loss on what is the problem. The customer swears that she hasn’t seen this happened before. My logic doesn’t explain it well, the element will off course glow red until it reaches temperature and I can’t see it for it work by not glowing.
Is it normal behaviour for the oven to do this?
