My refrigerator is making ice fine, but has been having issues with dispensing the ice. After some investigating these are the symptoms the ice maker/dispenser are showing:
The motor that rotates the ice out of the tray is only working when crushed ice is selected, it doesn't work at all when cubed ice is selected.
The flapper that releases the ice from the ice tray is not being opened by the pneumatic solenoid.
On rare occasion everything will work fine.

Since the solenoid and motor are in the same housing I bought a replacement Case Auger Unit that includes all the dispensing items, but after replacing it the same problems exist.
I'm thinking the pcb might be the issue but am not sure. Does anyone have any insight on this?
