Locate the white plastic Assembly Spacer part.

Make sure that the flat side of the Assembly Spacer is facing up when orienting it relative to the Control Board.

Position the Assembly Spacer above the nine components P1-7 and S2-3 and slide it down onto them.

The Assembly Spacer should rest on top of the nine components with no gaps. All nine component shafts should be extending upwards through the Assembly Spacer as shown.
