I can't find a schematic for your machine, but a lot (almost all) of these components are plug in type now, where the older ones used to be soldered in. I would get a part number for the light component, then look it up and find a pic. If it's plug in, you can easily remove the old part and just plug in the new part. first, though... I would also take the face plate off of the machine and check to see that the plugs are all seated properly, sometimes they can be vibrate just loose enough to trigger a malfunction. If you can't find a pic, post the part number and I can try and find it for you.
