Question about Panasonic NN-S254BF Microwave Oven

Panasonic Model nn-s252bf.....not heating probably

In have this issue with my microwave.  We purchased the item new in 2003, it worked great for the first couple of years while we were in our new home, however, we seem to be having a heating issue.  For example; it used to just take 2:30 to heat up a bag of popcorn, now takes like 5 minutes.  Sa,e goes for boiling water, only 1 minute then, now more like 2-3 minutes.  It is an over the range type, we really like how it matches our kitchen and hope this isn't something drastic, maybe just a blown fuse in the microwave itself that I could easily repair.  Any suggestions would be greatly appreciated.

Panasonic NN-H664

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.
