1. Most circuit problems are due to incorrect assembly, always double-
check that your circuit exactly matches the drawing for it.
2. Be sure that parts with positive/negative markings are positioned as
per the drawing.
3. Sometimes the light bulbs come loose, tighten them as needed. Use
care since glass bulbs can shatter.
4. Be sure that all connections are securely snapped.
5. Try replacing the batteries.
6. If the motor spins but does not balance the fan, check the black
plastic piece with three prongs on the motor shaft. Be sure that it is
at the top of the shaft.
Radio Shack is not responsible for parts damaged due to incorrect wiring.
