Query: Died after 5 months

I purchased the Panasonic NN-T764SF microwave in June of 2004 and it stopped working this past weekend (October 2004). Other than it being dead... while it was working it didn't seem to have the power output that it states. My previous microwave was a lower wattage but it heated items much faster... maybe it's because the cubic footage is a little larger???
