Hopfully this link will work .It shows step- by step instructions for bulb replacement.

The door switches should be checked, often food partical buildup will cause one or more to malfunction.

That I can't answer! But I would replace your microwave/convection oven, it is completely unsafe and a major fire hazard, and I would get in touch with GE and lodge a formal complaint about their product, if there is a flaw in the design it needs to be brought to the table to warn others that have same item so they are not affected in the same way.

Microwaves are pretty much a non repair item. It will cost you more to fix than it would to replace.

Check your power setting, making sure that you are cooking at 100%. Adjust if necessary.
It could also be a bad magnetron.

You have a bad door swicth or a bad wiring connector to one of the door switches... secondary swicth or the door sense switch.
