Microwave oven goes kaput

I think it is the result of a power surge we had during a storm the other
night. My question is, would it be worth fixing or should we just buy a new
one. It is about 7 years old, Panasonic from Sam's.

Buy a new one. If you shop around you'll likely pay less
than you will for even the simplest repair job. At 7 years
your old unit is well past its best.

Ditto. I got a 1300 Watt Panasonic for less than 100.00.

Microwave ovens are like toasters. Toss it and buy another and don't buy a
warranty.
Also, lots of luck with the power company. I lost my last one due to their
fault - not trimming trees - and they said it was an act of God and would
not pay anything. Make sure you put a surge protector on the new one.

I would call a service center and ask how much for an estimate of
repair . Then go buy a new one.

The last one I bought from Wal-mart was less than the cost of getting
a repair estimate .
