Thanks a lot for your replay. Maybe the reason why the compressor did not startet and popped the 220 V switch is really because I did not wait with stopping and starting the compressor. I did not know it could be an issue. When I wait like you said, it start every time without a problem. I think that it must be a foult thermostat. If the sensor is warm enough (too much then it should), the compressor starts normal and it works fine.
