Need part number - GE microwave

Same problem as one of the earlier threads - light bulb blew and now no light or fan. Tried to replace the bulb but still nothing.

In the other thread a diagram and part numbers were provided for a GW JVM1660. I tried to look up the diagram and part numbers for the JVM1440 and the response was there was no diagram available.

  1. Is the problem most likely the controller board as stated in the other thread

  2. What would the part number, availability and cost for the part be?

Thanks, James
