The black ribbon cable does not fit into the grey connector of the extension board?
The new extension board has a grey connector for the ribbon cable:
- The existing black ribbon cable leading from the extension board to the control board must be replaced with the enclosed grey/white ribbon cable.
- The black connector at the control board may have to be adjusted with pliers for this purpose.

Unplug black ribbon cable at the control board
Carefully adjust the black connector at the control board
