Your schematic part number 217 broke off in refrigerator (back) but is still attached to part 222. Do I need both? Do I need also parts 218 and 219 to complete repair? Also how to repair by myself?
For the parts that you will need to make the repair, you should only need the dial WR32X10154 and the knob WR02X10666. To access this the assembly appears to be held in by a couple of screws that would need to be removed. Once removed you should be able to replace the dial and knob.
