Main Control Board
The main control board manages the DC power distribution and communication bus for the entire appliance. Blinking dispenser lights are a known failure mode where the board's power regulation circuit fails to provide a steady voltage to the door-mounted electronics, causing the UI processor to repeatedly restart. Replacing the board restores a clean DC signal and stable communication timing.

Dispenser User Interface Board
Internal corruption of the LED driver or the UI's local microprocessor can lead to erratic display behavior. If the main board is providing stable voltage, the UI board's logic gates may be stuck in a failure state due to moisture ingress or electrostatic discharge, necessitating a full module replacement.
