Failing MCU

Capacitors on motor board drying out.

3
Wire chafing in cabinet

Harness routed against a sharp edge.

How to Fix It

  1. Reseat all harnesses between main and motor control boards.
  2. Inspect harness routing for chafing; re-tape or re-route.
  3. Look for bulged or leaking capacitors on the MCU.
