Any recommendations on an appliance repair person? I need someone to look at my gas oven. Used it almost 2 week ago, and we heard a loud bang and smelled gas. Nat'l Grid came to check it out. Said no gas leak. Said we can use the stove top, but wouldn't use the oven, just to be on the safe side.. Don't want to spend hundreds of dollars for someone to "look",then I may as well start shopping around for a new one!Thanks in advance.
