Possible Causes

How to Fix / Troubleshooting

Safety first: Unplug the freezer before removing the control panel or display housing.

  • Inspect the control panel: Remove the front display trim (usually clipped or screwed). Check for signs of moisture, condensation, or corrosion on the keypad and circuit board.
  • Check connectors: Locate the ribbon cable or harness connecting the user interface to the main PCB. Disconnect and reconnect it firmly, ensuring it is not twisted or damaged.
  • Dry the area: If moisture is present, gently dry with a soft cloth and allow the panel to air dry completely before reassembly. Do not use heat guns or hair dryers directly on electronics.
  • Power cycle: After reassembly, plug the freezer back in and see if the A6 code clears. Try operating the buttons to confirm response.

When to call a technician: If the display remains unresponsive or the error returns, the user interface board or main PCB may need replacement and should be diagnosed by a professional.
