Sub-Zero Refrigerator Ice Maker Overflowing? Try This…
Sub-Zero refrigerator ice makers are a common household appliance. When they don’t make the ice your family’s cold drinks rely on, including ice that smells and tastes bad, it can be pretty frustrating. And on the contrary, when they make too much ice and overflow, it can be a real mess. Thankfully, this common problem has a few common causes. Let’s look at five of the top reasons your Sub-Zero refrigerator ice maker overflowing may be occurring.

Misaligned Ice Bin
The Sub-Zero refrigerator ice maker overflowing may be caused by the ice bin not being correctly aligned with the ice maker. Does your Sub-Zero ice maker make too much ice? If the ice bin is not in the correct position, the sensors will not detect that the container is full, and will cause the ice maker to run continuously. You will need to realign the ice bin into its appropriate location to fix this. Take a look at your Sub-Zero refrigerator owner’s manual for detailed instructions on positioning your ice maker’s ice bin correctly.
Check the Max Ice Feature
Sub-Zero refrigerator ice makers make a lot of ice. Sometimes too much. If it’s making too much ice, there is a Max Ice feature that you can turn on and off. This Sub-Zero refrigerator ice maker feature is generally controlled by a switch on the back of your ice maker. Once you turn off this switch, your Sub-Zero fridge will stop making so much ice.
If the Max Ice Feature is mistakenly turned on or left on, the simple flip of a switch may be your solution to your Sub-Zero refrigerator ice maker overflowing.
Check the Ice Maker Shut-Off Arm

If the ice maker shut-off arm malfunctions, it can cause the problem of a Sub-Zero ice maker overflowing.

To make sure the icemaker switch arm is connected correctly, open the freezer door and find the small metal arm on the side of the icemaker. The ice maker should be upright and linked to the freezer.
