The light in microwave doesn't go off when door is closed ?
Once I close the microwave door the light is still on and the microwave will not start but a message appears saying shut microwave door but the door is shut
One of the two or three safety switches that tells the microwave its door is shut has failed - or the operating tab on the door has broken off. Unless you know EXACTLY what you are doing (and, based on your question, you won't) then don't risk the lives o fyour family by attempting a repair yourself. get a techie to do it or simply get a new microwave.

There will be a crafty mechanism that senses that the door is closed - a small switch very probably. It will be defective.
Your appliance needs to be seen by a specialist - either that or you consider buying a replacement.
