I was last out on this refrigerator approximately 15 days ago and done a wire trace on everything coming out of the door and found nothing open. I done continuity checks from the user interface all the way back to the main motherboard. I'm not one to give up on something very easily but considering I've got hours and hours into this thing and a board with a core charge that I can't get money back on I give my customer his money back and told him to call somebody else. I hate being defeated and I hate giving money back. I was hoping someone may have run into a similar problem on this low volt motor design. This design calls for 14 VDC coming out of the main board 2 the auger motor. I did not have that 14 volts DC coming out of the main board. That only leaves the user interface and connecting wiring. Scratching my head.
