ide take it to a white goods repairer because it will be under worrenty

Convection contact solenoid is stuck you will have to open the unit and try tapping them all with a light screw driver to free them up lightly NOT bang them they are thin plastic. If i can help further just shout remember to rate my help also thanks in advance.

Unplug the oven and remove the top/side cover. Check for loose screws on the hinge mounts, and examine the door carefully there to see just where the play is if the screws are tight. There's a high probability it's due to worn pivot bushings. I haven't yet taken a door apart to fix this problem (although I need to do it on my 30-year old Panasonic unit), so I'm not prepared to describe how to do that. Depending on how it's put together, you may be able to loosen the screws, adjust the door so it fits better, then tighten the screws again.

need model number

It should not be too difficult, but the fault could also be a failure of the HV transformer or the big capacitor in that circuit. http://www.repairfaq.org/sam/micfaq.htm As you may be aware, the main precaution is to make sure the HV capacitor is fully discharged before you work on that circuit. https://www.youtube.com/watch?v=OFFzS1a6k5g Some have a self discharge resistor, but that also can fail. Here is a typical circuit http://www.microtechfactoryservice.com/images/doubleranim_a.gif and the diagram for your unit may be pasted to the inside of the casing. If you are sure it is the magnetron, you only have to discern the mechanical fixings of it after that.

I think your local repair profesional is your best bet in this case.
