Display shows E17; high temperature alarm may sound and temperatures may be too warm.

Safety first: No internal live-voltage work is required for basic checks, but unplug the unit if removing panels.

Steps:

• Check doors and gaskets: Ensure all doors close fully and gaskets are sealing. Look for torn or warped sections.
• Verify loading: Avoid blocking air vents with food items, especially near the back wall and top of the compartments.
• Thermometer check: Place an appliance thermometer in both compartments to verify actual temperatures versus display readings.
• Sensor diagnostics: If the display shows unrealistic temperatures compared to a thermometer, test the compartment thermistors as described for E1/E2.

Corrective action: Correct any airflow or door seal issues. Replace faulty thermistors if sensor readings are inaccurate. Clear the alarm by pressing the alarm reset button or cycling power.
