I got new wall oven. It was working for a while now it's not working. Oven light, clock and all buttons are working but the when I set it for bake it does not warm up. I have it connected directly to 220 volt outlet. Do I need fuse panel between oven and power outlet?

Check the 220 outlet, it sounds like one side of the 220 is not working. That is why the 110 itms like light and clock would still work.

If you are not getting 220 at the outlet, then check the main breaker pannel.

But if you don't know what to look for or what you are doing, this is too dangerous so call a professional.

Chucks idea is a great place to start, and if that doesn't get it, it sounds like you may have burned a wire off an element. I find it hard to believe that a new element has went out already, so its most likley a loose wire connection.

I don't know how complex your oven is, but on a simple electric oven circuit, normally a thermostat controls controls the oven element. In newer ovens, there may be a cicruit board to two involved, maybe a solid state thermostat, but to say the least, voltage should come out of it. All of the residential ovens I have taken apart didn't have a contactor, but that doesn't mean you don't per-se.

As chuck said, if you are unsure about any of this, then call a professional. The only way to correctly troubleshoot this would be to remove the panels to access the insides, then energize the oven so you can determine where voltage stops.
As you can imagine, this can be dangourous if you are not careful.

What is the brand and model number of your oven? Perhaps I can dig up a wiring diagram.
