Hi! The small 6V brushless DC motor went wrong. I had the same issue. You can replace it with one from a PC DVD reader (this is the door opener motor). Shaft is smaller but it's ok, diameter is good. I used a disassembly instruction from here: Disassembly Be careful with clips, use a small screwdriver and push the fixing inner parts. With this you can avoid the damage. You need a solder iron as well to replace electronic part from DC motor. Now my daughter's Furby is working again!
