E14 error; display may go blank intermittently or show garbled characters.

Safety first: Disconnect power before removing the display assembly. Avoid flexing the display PCB excessively.

Step-by-step checks:

• 1. Inspect for condensation: If the freezer is in a humid environment, moisture can condense inside the control housing. Remove the panel and check for droplets or corrosion. Dry thoroughly.
• 2. Reseat connectors: Unplug and replug the display ribbon cable and power connector. Ensure they are fully seated.
• 3. Visual inspection: Look for burnt components or cracked solder joints on the display PCB, especially around the voltage regulator and connector pins.
• 4. Replace display module: If reseating and drying do not resolve the issue, replace the display module with a compatible Hansa part.
