To make sure, turn every breaker firmly to the "off" position, then turn each breaker back to the "on" position...sometimes a breaker will have tripped, but it does not visually appear to have tripped.
The stove fan was also not working so I checked the breakers. No breakers were thrown.
Did you test these other appliances on another circuit? Do they spring "back to life", or are they truly dead? If these other appliances work Ok on another circuit, then you have a loose connection of some kind. On the other hand, if these other appliances have truly "died" and do not work, then I am concerned there may be an over-voltage problem. Do you see a red wire in the "dead" receptacle box (turn off the fuse first, let everyone else in the house know not to turn the breaker back on while you're working, and TEST to make sure the wires are de-energized before you start poking around)?
Other power problems that might be oddly related, or perhaps unrelated, are that 6 weeks previously the counter-top toaster-oven oven portion stopped working (I don't see how this relates.) 2 weeks previously an even older microwave died when plugged into the now-dead outlet.
I would imagine that there are plenty of other lights and/or outlets on this circuit. You should check to see what else is on this circuit. The microwave is a high-current-draw appliance and will not tolerate much other load before it will indeed trip a breaker.
I've moved the microwave so Christmas Eve and Day can continue without much hiccuping and the outlet it's now plugged into has a device that turns one outlet into 6 with it's own breaker. That breaker blows whenever the microwave is run for more than 5 minutes.
Post back once you've had a look-see and we'll give you more help. If you are not comfortable, do call an electrician.
