So this is model #PVM9005SJ1SS and it is only 4 years old and it just shut down one day after cooking something. Flipped breaker and that did nothing. Took down and checked outlet which was fine. Since the controls are all in the door it is not easy to take apart to check fuse. Did notice there had been complaints about the wires going to the controls in the door getting cut by the door being open and closed. Checked and 2 wires where cut. Took door off and soldered wires back together. This did not work. Took panels off and checked fuse and it was fine and everything else looked good. Put is back together and plugged in and it worked!! Put it back over the stove. Cooked some corn for 5 minutes and when it beeped it then just shut completely off again! Tried flipping breaker again and nothing. I need help! I hate to just junk a 4 year old microwave that cost $400!
