Question about Microwave Ovens
Since that's a European model, I don't have solid info on it.
If it's an inverter-equipped oven, it may be a problem with the inverter or magnetron.
Otherwise, I would first suspect this to be a door switch issue or a bad door switch mount.
You could try holding up or down (alternately) on the door to see if that changes the performance.
Another possibility is the damper. Normally they will run for 49 seconds and then stop when the damper system has a problem, but maybe a non-US market has different requirements...
Please see the diagram below for a typical convection damper system.
