My 1200W microwave oven no longer heats. Since the electronics
package still works and the motorized platter turns, I presume that I
need a new magnetron. How can I verify this?

In general, if we're otherwise satisfied with the oven, does it make
sense to replace the magnetron? Or is the cost probably going to be
at least 50% of the price of a new oven?
