Symptoms

  • F6E0 on display, sometimes with display going dark intermittently
  • Buttons unresponsive
  • Code may clear briefly then return

Common Causes

1
Loose or damaged ribbon between UI and main control

Vibration or a bad seat at a ZIF socket interrupts the data line.

2
Failed user interface board

The UI/display board has lost its communications chip or its power rail.

3
Failed main appliance control (oven appliance manager)

The other end of the bus has died and stops responding.

How to Fix It

  1. Disconnect power at the breaker for at least 1 minute, restore, and watch for the code.
  2. If F6E0 returns, kill power again and access both the UI board (behind the keypad) and the main control board.
  3. Reseat the ribbon/harness between them at both ends; check for crushed pins.
  4. Inspect each board for burn marks, swollen capacitors, or scorched traces.
  5. Replace whichever board shows damage. If neither shows damage, the tech sheet sequence is to replace the user interface board first, then the main appliance control if that doesn't resolve it.
  6. After replacement, run a bake test to confirm normal communication and operation.
