I have a LG Microwave oven, model #MV-154SJ. When pressing Time Cook, the Microwave no longer heats. The light comes on like it would start heating but the usual humming sound is no longer there and the turntable no longer turns. It's like I would only put the timer on and not the time for cooking. Checked the breaker, checked the door, but everything seems to be fine. Read the manual but it does not talk about fuses. Please help.
