What you may notice with 10

• The display shows the number 10
• The second door is slightly ajar
• Warm air or a draft comes from the gap
• The number stays on even after you think the door is shut

How the ice machine detects 10

The second door has a switch, and that switch tells the control whether the door is closed. When the door sits tightly against the cabinet, the switch is in its closed position and the display shows normal information. When the door swings open or is not fully shut, the switch changes state.

The control reads the change and puts the number 10 on the display, which is how this unit names the second door being open. The alert helps you spot a door that did not latch before warm air gets in and softens the ice. Once the switch sees the door closed again, the number should leave the display and normal readings return.

Why 10 appears

• The second door was left ajar
• A worn gasket keeps the second door from sealing
• A door switch that reports open when the door is closed

Can you keep using the ice machine with 10?

Yes, the ice maker is safe to keep using, because 10 is a door indication and not a failure. Close the second door firmly and give the unit time to recover. If the number stays up with the door closed, or the ice becomes wet, have the gasket and door switch inspected.

What you can safely check

1. Before touching the door, shut the ice maker down at its breaker and keep fingers away from the hinge.
2. Close the second door fully and listen for it to seat.
3. Look for anything sticking out that prevents the door from closing.
4. Check the gasket for a tear or a curled edge.
5. If 10 stays on the display with the door shut and clear, call us.

What our technician does for 10

• Test the second door switch for correct open and closed signals
• Inspect the gasket and hinges on that door
• Check the door alignment against the cabinet

How to keep 10 from coming back

• Push the second door shut until it latches every time
• Keep items from sticking out into the door path
• Wipe the gasket so it seals evenly along the full edge
• Check that the unit sits level so the door closes by itself
