Why Is My Sub-Zero Ice Maker Not Making Enough Ice?

Sub-Zero ice maker not making enough ice

Sub-Zero refrigerators are known for their quality and durability, but even the best products sometimes have issues. In this blog post, we’ll discuss some of the most common causes for a Sub-Zero ice maker not making enough ice. We’ll also provide some tips on how to troubleshoot the problem. So if your Sub-Zero is suddenly producing less ice than usual, or not producing ice at all, read on for help!

How Much Ice Should My Sub-Zero Ice Maker Produce?

According to Sub-Zero, its ice makers produce an average of eight ice cubes every two to three hours. If you feel like your ice maker is falling short of this mark there are a few things to consider. First, check the production limits and bin capacity. These can vary depending on the model of your Sub-Zero. If your Sub-Zero ice maker is producing too much ice, check out our resource here.

How Long Does it Take for a Sub-Zero Refrigerator to Make Ice?

Depending on the model, it may take 1-2 days to completely fill the ice bin. However, this can vary depending on the model and how often the door is opened. If you’ve been opening the refrigerator frequently, it may take longer for the ice maker to produce a full batch of ice.

Common Causes of a Sub-Zero Ice Maker Not Making Enough Ice

There are a few different reasons why your Sub-Zero ice maker might not be making enough ice. The most common causes are listed below:

Sub-Zero Ice Maker Bin Is Full

One common reason for a Sub-Zero ice maker not making enough ice is that the bin is full. The ice maker will only produce as much ice as the bin can hold, so if the bin is full, the ice production will stop. This is usually not a problem if you empty the bin regularly, but if you forget to do so, it can lead to ice build-up and eventually cause the ice maker to stop working altogether. If you think this might be the problem, simply empty the bin and see if ice production resumes.

Jammed Ice Cube

If the ice maker isn’t making enough ice, it’s possible that the ice cube tray is jammed. This can happen if the ice cubes get stuck together or if something is blocking the tray. To fix this, remove the ice cube tray and make sure that nothing is blocking it. You may also need to clean the tray if there’s build-up on it.

Dirty Coils

Another common cause of a Sub-Zero ice maker not making enough ice is dirt and debris build-up. Over time, dust and other particles can accumulate on the ice maker’s evaporator coils. This build-up insulates the coils and prevents them from absorbing heat properly, which in turn reduces ice production. If you think this might be the problem, clean the coils with a soft brush or cloth and see if ice production increases.

Water Supply Pressure Is Too Low

Another common cause of a Sub-Zero ice maker not making enough ice is that the water supply pressure is too low. The ice maker needs a certain amount of water pressure to function properly, so if the pressure is too low, it won’t be able to produce as much ice.

Sub-Zero Ice Maker Is Not Making Ice

If you’re Sub-Zero ice maker isn’t producing ice at all, then there are a few things you can check.

Ice Maker Is Turned Off

First, make sure that the ice maker is turned on. If your Sub-Zero refrigerator was recently installed, it may take up to 24 hours for a batch of ice to be produced.

Frozen Ice Maker Fill Tube

The ice maker fill tube can become blocked by ice. This can reduce the amount of water that flows into the ice maker and eventually lead to no ice production. If your ice maker fill tube is frozen, this may be a sign of something more serious, so it’s recommended to call a qualified technician.

Freezer Temperature Is Too High

If the freezer temperature is too high, the ice maker won’t be able to produce ice. The ideal freezer temperature for a Sub-Zero ice maker is at or below five degrees Fahrenheit. If the freezer temperature is higher than this, you’ll need to adjust it.

These are some common reasons why your Sub-Zero ice maker might not be producing enough ice. If you’re still having trouble, feel free to reach out to our Sub-Zero refrigeration experts DeserTech.
