SOURCE: Microwave works intermittently
This is most commonly due to a failing door switch or door switch mount. But it may also be a bad connection or bad relay on the control board, which we repair nationwide for $39.95. Also, it could be a loose connection at the magnetron. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams for similar models here: http://tinyurl.com/gv383 You can order parts at http://www.wehaveparts.com

I also bombed out on locating a downloadable manual but the hardcopy is available on eBay here:
The efficiency of microwave oven is ~ 65% so if you will check the back of your unit for the AC line (input power) consumed, you can easily calculate the usable 'cooking' power available.
i.e. If the label states: 115 VAC 10 Amp(eres), this would amount to 10 X 115 = 1150 X .65 = ~ 740 watts delivered to the food.
The magnetrons do age (if not fail first) and their emissions fall with progressive use so a 10 year-old oven won't still give you that ~65% but substantially less.

I have replaced the main fuse on this model. Though blown main fuses are common in this model, it will not even turn on when they blow, so your problem is most likely NOT a blown fuse. I had heard of your problem so, when replacing the main fuse inside one, I looked for additional fuses and saw none. The store was wrong. Even if it were a fuse, the security Torx screws mean that you couldn't replace the fuse anyway.
This microwave seems to have been haphazarly been recommended by Consumer Reports, but it is terribly unreliable. The turntables break when popping popcorn, the main fuse repeatedly blows, and they also stop heating.
