Freezer shows error code E8 and may not respond to temperature setting changes; display may freeze or show dashes.

Safety first: Disconnect mains power before accessing the control board compartment.

• Power reset: Unplug the freezer for at least 10 minutes to allow capacitors to discharge, then reconnect and check if E8 clears.
• Inspect board area: Remove the control board cover (often at the rear or top). Look for burnt components, strong odors, or visible damage.
• Check harnesses: Ensure all connectors are firmly seated and no wires are pinched or damaged.

When to call a technician: E8 usually indicates a board-level fault. Replacement or reprogramming of the main PCB should be performed by an authorized service center.
