General

1 check

If you see

Nothing works — lights are off and the triangles are not rotating.

Then check

Open the poster case door and press the on-off switches for the motor and the lights.
Check the fuse, which is located to the right of the on-off switches.

Lighting

3 checks

If you see

Some lights are out.

Unscrew and slide out the light tray and then replace old lamps with new lamps.

If you see

Then check

One of the electronic transformers is burned out.

If you see

All lights are out.

Then check

Both electronic transformers are burned out.
Remote possibility of a short or wiring problem.

Triangle Rotation

4 checks

If you see

Some triangles are rotating and others are not rotating.

Then check

Make sure that the triangle is snapped into its gear by pushing the triangle up from the bottom towards the top. If the triangles are snapped in then it is likely that a gear is stripped and needs to be replaced. If not snap it in you may need to loosen the set screw first then snap up the triangle and re tighten the screw.

If you see

No triangles are rotating.

Then check

Check that the coupler between the motor and the drive shaft is securely fastened.

If you see

Coupler is secured and no triangles are rotating.

Then check

Loosen allen screw to detach coupler from drive shaft. Press on-off switch for motor to see if the motor is rotating the coupler while the drive shaft is disconnected.
If the coupler rotates then the motor is OK and one or more of the gears are jammed.

If you see

One or more gears are jammed or stripped.

Then check

Replacement gears and replacement instructions will be needed. For jammed gears order at least two replacement gears. To determine if additional gears are stripped, gently touch the edge of each triangle by hand. If any triangle rotates when touched its gear is stripped and needs to be replaced.

DO NOT FORCE ROTATION by hand.
