How Do You Fix A Sub-Zero Ice Maker?

Let’s first understand how Sub Zero ice makers work. By knowing what is normal, you will know when things go abnormal! You can troubleshoot issues before they get worse. The process is quite simple, so strap in and keep reading.

These ice makers fill a mold with water and freeze it. This way, the water freezes to form ice and can then be ejected into a storage bin. These cubes are then ready to use whenever you need the ice cubes!

The process is made efficient using various components – from water supply lines for a smooth flow to inlet valves. You can see the ice molds outside the ice maker but various gears and motors work behind the scenes tirelessly.

That’s how you get good ice at the ready. Now that you know which components do what, you will better understand how to troubleshoot issues when they arise.

Common Concerns You May Face with Sub Zero Ice Makers

Your ice maker might be causing issues for various reasons. Maybe you opened the storage bin but there was no ice there. Or maybe you hear strange noises or whirring sounds from the ice maker. Or maybe your ice maker just won’t turn on.

Here are some common concerns and how to fix them:

Ice Maker Not Producing Ice

Is your Sub Zero not making ice? Have a stubborn ice maker that refuses to produce ice? We feel you! Here are some reasons why your ice maker is having a bad day:

Water Supply Issue

First, check if the water supply line is connected correctly and if water is freely flowing through it. Sometimes, a twisted or blocked water supply line can prevent the ice maker from doing its job and producing ice.

Faulty Water Inlet Valve

This is the part of your ice maker that regulates the water flow into the ice maker. If it isn’t working properly, then your ice won’t get produced as there is no water to freeze. Get the valve replaced to restore proper water flow and fix the issue.

Ice Maker Producing Thin Ice

There are times when your ice maker still produces ice but it is too thin. Ever seen hollow ice cubes or cloudy ones? Impure water can account for cloudy ice cubes, but for thin ones, the issue is quite different.

Low Water Pressure

Your ice maker needs adequate pressure to form ice cubes. If there is not enough pressure, your ice maker will produce very thin ones. Check if your water pressure is enough, else install a booster pump to get it working. Be sure to address this issue before getting an ice maker. If you don’t have good water pressure at your location, then there is no use getting an ice maker without a backup plan!

Faulty Ice Mold Thermostat

You need a mold thermostat to regulate the temperature of the water and ice cubes. Only then will they form correctly and retain their shape before you take them out. If the thermostat isn’t working correctly, replace it and you will notice better consistency for your ice cubes.

Ice Maker Making Strange Noises

If your Sub Zero refrigerator ice maker is making loud and strange noises, it is time to check it immediately. Here are a couple of possible reasons your ice maker is behaving badly:

Ice Buildup

If there is a significant amount of ice buildup within the ice maker, it can result in abnormal noises. When you notice your Sub Zero freezer not making ice, it’s important to clean the ice maker, ensuring that any accumulated ice is removed.

Worn-out Motor

Over time, the motor responsible for ejecting the ice cubes into the storage bin can become worn out. This wear and tear can lead to unusual noises emanating from the ice maker. If you suspect a worn-out motor as the cause, it may be necessary to have it replaced to restore normal operation and silence the unusual noises.

Troubleshooting Steps for Sub Zero Ice Makers

Your first instinct when you see broken ice makers might be to get them replaced. How long do Sub-Zero ice makers last, you ask? They last a year or even more based on how well you maintain them.

If you can relate to any of the issues mentioned, let’s get troubleshooting:

Check the Water Supply

If your ice maker isn’t producing ice, you can suspect a lack of water or a disruption in the water supply line. Get it checked to ensure it isn’t obstructed in any way to let water flow smoothly. Check the water pressure and adjust it to optimum while resolving any leaks. If there doesn’t seem to be any issue, try the next step.

Inspect the Water Inlet Valve

Check the water inlet valve if the water supply is working fine. If it isn’t functioning right, call a professional technician to replace the valve. It is best to not resort to DIY tactics in such cases as valves are expensive and can damage your entire ice maker.

Examine the Ice Maker Assembly

Check the ice maker’s assembly for any damage or blocks. Sometimes, if there is a block or clog formed due to pressure, the ice maker won’t form ice. Clean the ice mold and remove any debris left from the previous usage. By cleaning all components, you can remove dirt and obstructions in the smooth flow.

Clean the Ice Maker

Use a mild cleaner and warm water while cleaning your ice maker. Carefully dismantle the parts and clean both the interior and exterior surfaces.

Reset the Ice Maker

In certain cases, performing a reset can resolve minor issues with your ice maker. To do this, it’s recommended to consult the manufacturer’s instructions or refer to the Sub Zero ice maker repair manual that came with your specific Sub Zero ice maker model.

When to Seek Professional Help

Tried all these steps and your ice maker still isn’t responding? Then it’s time to take it on a trip to a professional! Get good assistance from a certified Sub Zero technician or a local one who specializes in this brand.

This is because certified professionals have the equipment and expertise to fix issues quickly. They take less time diagnosing the problem and more time getting it fixed. You could get it done for cheap or even for free if your warranty period is still ongoing.
