Hi i have a Newworld built in oven with grill. The problem i`m having is that when i turn the grill knob for the grill to come on it trips out my main fuse box leaving me with no power in the house atall untill i turn the knob back and reset my fuse box, my oven works fine its just the grill. Do you think its worth replacing the grill element or just fork out for a new oven, any help would be great, regards paul
