Elizabeth, without access to a service manual, even an experienced electronics technician with no experience with the KN7000 would probably have problems with the disassembly nessary for getting to the dial wheel.

I have a service manual for the KN7000. The part number used is QGUG3002BC. I do not have a service manual for the KN6000. Maybe someone else with a KN6000 service manual could compare part numbers to see if the dial from your KN6000 might work.

The Printed Circuit Board (PCB) for the encoder switch (dial wheel) has a part number SXPG239011B. The schematic symbol for the switch is SW1101.
