EE4 means the line voltage is too high. Usually this is fixed by resetting the voltage selector on the back.
The voltage selector may not look like a switch, looking rather like a metal panel that has to be taken off and reoriented. There will be a label next to it indicating a voltage number.
EE2 actually means that the control circuit senses that magnetron number 2 is not running.
It doesn't necessarily mean a bad magnetron.
This can be due to a bad or misaligned door switch (common), a failed relay (#3) on the control panel, or a failed high voltage component such as transformer #2, capacitor #2, rectifier #2 or magnetron #2 or loose connections anywhere along the chain.
We have a similar model's service manual on our site. Please not that yours may be different! Part numbers will probably not match. But it will help with safety, disassembly, discharge and diagnosis.

If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.
