How to Fix / Troubleshooting

Safety First: Disconnect power before servicing the console.

Steps:

  • Verify part numbers: Confirm that any recently replaced UI or main control board matches the exact Kenmore model and revision.
  • Reseat connectors: Unplug and reconnect the UI-to-control harness, ensuring a snug fit.
  • Inspect harness: Look for pinched or damaged wires between the console and main control.
  • Replace incorrect parts: If an incompatible board was installed, replace it with the correct OEM part.
  • Board diagnosis: If all parts are correct and wiring is good, either the UI or main control may be defective and require replacement.
