My microwave is 25 years old, will it be working to maximum efficiency

Using an electrical tester you will be able to trouble shoot the issue quickly.

Probably a problem with the door latch safety system. This happens every so often with our microwave, which is over 25 years old, and otherwise works perfectly.
If yours is new, it may still be under warranty. If not, there are places that specialize in fixing microwave ovens.
If it is an older, or less expensive oven, it might be time for a new one.

After 16 years, I should think you had your money's worth from this machine.
There are a few arguments for fixing it, if it's repairable, but a new one will be more powerful while being more efficient too. (use less electric)
Less radiation leakage too.. (pacemaker exposure?)

Perhaps you should first try shopping around to see if you find one that you like, and that fits in the space you have for it, etc. If you buy a new one, get a good one. Don't go cheap.
If one seems to make good sense to you, then buy it. If nothing looks good to you then find a repair shop to take old one to.

Why would you keep old one? Well first of all, they don't make them like they used to. Lot of new ones are noisy and rattle a lot. Don't last nearly as long. Many new ones have problems early.

Old ones are lower power, which is slower, BUT food heats more evenly because of it. Less prone to exploding food.

It would be much easier, and cost efficient to replace the Microwave, especially if no heat is being generated.

If the light, or turntable went out or something, maybe then a repair would be more reasonable.

Um, no. You can get a new microwave that is much, much more efficient for a fraction of the repair cost.

Check fuses or count yourself lucky that you got 25 years out of anything. Buy a new one...there relatively cheap and work more efficiently. This old one probably leaks radiation anyway.

Sadly Kenmore only offers parts for 10 years. The truth is a new microwave for 50 dollars will be much more energy efficient than your 21 yr. old model

look at the features the new microwaves have. alot of them have a button to turn the turn table off
