The microwave was workign fine the it stopped heating. Everything seems to work ok, power level at 10, light comes on fan runs, but there is no heating (microwaving) any ideas of what it may be?

You can help us with the diagnosis, if you have a meter and can do a few electrical tests. If you don't own a meter, you can get one for a very reasonable price at any electronics store. First check the outlet to make sure you have 120VAC, and that it is the proper polarity. Again, you can find a very inexpensive outlet tester almost anywhere, including Walmart.

Ok, then:
Remove the cover and discharge the capacitor (after you have unplugged it, of course). Disconnect the power transformer secondary wires (these are the wires going to the capacitor and the magnetron). Plug the machine back in and select a cooking time and while it's running, check for 120VAC at the transformer primary wires. If no voltage (or considerably lower than 120V), the problem is in the control board. If you get the proper voltage, the problem is one of the high voltage components. Post your results.
