Set built-in DCS model MO-24SS microwave for 1 minute at high and turned on. Started to smell a burning smell -- not a food burning smell -- more like a fire burning smell. Turned it off immediately. Was on maybe 15-30 seconds. No food was burned, no food debris inside microwave. Unit was no hot to touch. No smoke. Afraid to turn it on again if it will start a fire. Unit is 7 years old -- this is first problem. Any suggestions?
