Electric breaker box not producing 220
It sounds like you lost a phase from your utility.  If you have overhead supply, that is the likeliest possibility.  You could open up the panel and check the breakers, but if you call the power company, the visit will be free and fast (assuming you didn't just have a windstorm, ice storm or other mass-outage event). 

Ideally you would get all dead 240V appliances and all dead 120V appliances on one pole.  What actually happens is (from the 240V appliance's perspective) one leg is connected to neutral via your 120V appliances, and (from the 120V appliance's perspective) their hot wire is connected to the other hot wire via the 240V appliances.
