Display shows E10 or similar numeric code, freezer may shut down or lock controls.

Safety first: Unplug the freezer before touching any electronic components.

• Step 1 – Hard reset: Disconnect power for at least 10 minutes to allow capacitors to discharge. Plug back in and observe if the code clears.
• Step 2 – Check for surges: If the error appeared after a storm or outage, consider using a surge protector rated for appliances once the unit is repaired.
• Step 3 – Inspect control board: Access the main control board (often in a rear control box). Look for burnt spots, bulging capacitors, or a burnt smell.
• Step 4 – Reseat connectors: Unplug and reconnect all harnesses to the board to ensure solid connections.
• Step 5 – Replace board if needed: If E10 persists and no external issues are found, the main control board likely needs replacement. This should be done using the correct JennAir part number and anti-static precautions.
