Freezer displays temperature but does not respond to button presses or touch controls.

Safety first: Unplug the freezer before opening the control panel if needed.

• Check for child lock: Consult the user manual for the key combination to unlock the controls (often holding a specific button for several seconds).
• Power reset: Disconnect power for 5 minutes and reconnect to reset the electronics.
• Inspect panel connections: If still unresponsive, remove the control panel and reseat the ribbon cable or harness.
• Replace UI board: If buttons remain dead, replace the user interface board with the correct Hotpoint-Ariston part.
