Possible Causes

Loose wiring harness between door lock and control, Intermittent door lock assembly, Oxidized connectors, Failing main control board

How to Fix / Troubleshooting

Safety first: Disconnect power before handling wiring.

  • Inspect harness routing: Ensure the harness from the lock to the control is not pinched by the cabinet or rubbing on sharp edges.
  • Clean and secure connectors: Unplug connectors at both the lock and control board, spray with electrical contact cleaner, and reconnect firmly.
  • Wiggle test: With the unit running (technician only), gently move the harness to see if the error can be induced. If so, replace the harness.
  • Replace door lock or control: If wiring is sound, replace the door lock assembly first. If E45 persists, the main control board may be at fault.
