We have panasonic mircrowave mode NN-S953WF.It was working perfectly alright this morning, My wife wanted to make a cup of tea and put the cup in and timed for 1.55 minutues. All the power in started for 30 seconds and stopped itself with no warm up and or boiled water. I checked external fuses, Everything seems fine except it stopes after 30 seconds
