You have a bad secondary interlock (lower door switch) or its mount is damaged or out of alignment.
We have
the service manual for this model and have uploaded it to our
site here to help you.
You will need the free
Acrobat Reader
to view or print it in case you don't have it.
Even though a door
switch clicks, it may still be bad inside.
Door switch
or mount trouble is usually caused by slamming the door or by opening
the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these
mounts may be loose. If they get too loose, the switches will not be
activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab
can be hard to see, since it is under the
bottom edge of the switch.
If you only need a
switch, you can order a universal type here for $5 postpaid.
We're
happy to help you with free advice and we'd appreciate your thoughtful
rating of our answer.

The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.
Regarding parts, contact the seller here to purchase parts.
You can also order from MicrowaveSvc , they also provide parts.

When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.
