Possible Causes
Control panel in test mode, Power-on self-test not completing, Stuck control buttons, Faulty user interface board
How to Fix / Troubleshooting
Safety first: This is a control-only issue; no internal high-voltage work is required if you only use the front panel.
- 1. Attempt to exit test mode: Press and hold the main control buttons (such as Lock and Settings) for 3–5 seconds. Refer to the Café manual for your model's exit sequence.
- 2. Power reset: Unplug the refrigerator or turn off the breaker for 5–10 minutes. Restore power and see if the display returns to normal temperature readout.
- 3. Check for stuck keys: Gently press each button on the control panel to ensure none are jammed. A stuck key can keep the UI in test mode.
- 4. Inspect UI harness (if accessible): If comfortable, remove the control panel trim and verify the ribbon cable or harness is fully seated.
- 5. Replace UI if needed: If the display remains locked in 88 88 and buttons do not respond, the user interface board may need replacement with an OEM Café part.
