Disassembled ice dispenser front panel to replace the water dispenser delivery tube. While doing this, the ribbon cable became disconnected from the front panel. Got some arcing as I tried to reconnect ribbon cable. (Thought that I had killed power with the on/off switch inside refrig; turned off power at main panel and reconnected ribbon cable.)
Ice and water dispenser worked fine for a couple days but on third day when getting ice, the auger wouldn't stop. Checked micro switch and auger relay and they seem fine. With ribbon cable disconnected, the auger won't run.
What diagnostic can I perform to determine if the problem is with the power board (with the relay) or the control board (with the buttons)? Also, the auger relay has a MOC driver/isolator, what diagnostics can be performed to determine if this is the problem component?
