Can Ice Maker Freeze Up?

Can Ice Maker Freeze Up?

Remember that if the ice inside the ice maker can not release off the evaporator plate, it’ll start to freeze up. Though that’s not that big of a deal in the short term, as water starts to flow over the evaporator plate, it creates a problem. It forms an ice block that interrupts the whole thing, causing the device to malfunction. Now you know what causes the ice maker freezing up issue, and it’s typically the main reason in most cases. That said, many other reasons can cause this issue that we’ll cover in the following segments. 

What causes Ice Maker to Freeze Up?

Let’s check out some of the most common causes of an ice maker freezing up right below:

Clogged Water Lines

A proper water flow is essential for ice maker machines. If the flow is too slow, the water line gets clogged with ice blocks, and it creates the whole machine to fail. It’s a very common cause of freeze-up of an ice maker.

Float Switch Malfunction

The float switch plays a massive role in monitoring and controlling how much water is used during a freeze cycle. But, if it fails to operate correctly, the ice machine suffers the consequences. In most cases, the ice maker will start freezing up.

Bin Control Issues

If you’re asking what makes ice maker freeze up, it can very likely be a bin control issue. It monitors how much ice is in the bin. When it starts to malfunction, the whole machine starts to fail. And, you’ll see that the ice machine won’t stop and will begin to freeze up due to the bin control failure.

Scale Formation

Scale is also responsible for your ice maker freezing up. Hard water inside the ice maker can result in scale formation. Remember, magnesium and calcium form together and stick to those surfaces where water keeps flowing continuously. So, you have probably seen scale forming on your shower tiles or around your faucet if you have hard water in your living area.

The Freezer temperature is too cold

Obviously, if the temperature in your ice maker is too cold, all the water will turn into ice too quickly. And, your freezer will suddenly become a giant block of ice that’s not wanted, right? 

6 Sure-fire tips on stopping Ice Maker Freezing Up

You already know all the possible causes why an ice maker can freeze up. It’s time to check out the possible fixes. Let’s get to know them straight away:

Check and Fix Clogged Up Parts

You should know that ice makers freeze up mostly because of clogged-up parts. So, the very first thing you should consider checking is whether something is clogged up and blocked or not. Check the water lines, inlet valves, water filter, etc., and see whether everything is operating smoothly or not. If you’ve found an ice block clogging up parts of your ice maker, it’s really an easy fix. Follow the steps below to quickly fix it.

  • Take a hairdryer and a dry towel as you’ll need them for this job.
  • Turn off the ice maker and remove the plug from the power socket.
  • Take out the bucket that collects the ice, and place the towel there so that it can soak up the excess water.
  • Turn on the blow dryer and use it to melt down any ice buildup that’s jamming or clogging up the mechanism.
  • Once done, put everything back together and turn on the machine. It should work properly again without any hiccups.

Solving Float Switch Issues

In most cases, float switch issues can be fixed by cleaning them. It’s best to clean it manually with an ice maker cleaner as it’s more effective. You should also leave the ice maker unplugged for a while so that the ice blocks melt, making your job easier. But in some scenarios, the float switch gets defected. In that case, you need to replace the float switch completely. That’ll solve the issue, and the ice maker will operate properly after replacing the defective float switch.

Fixing Bin Controller Issues

If the bin thermistor is defective, the freezer’s light will blink twice in 2 seconds intervals, and that’s how you know you have bin controller issues. Luckily, it can be fixed pretty easily by following the steps.

  • First, get a new bin thermistor from the market and a screwdriver.
  • Turn off the ice maker and unplug it completely. 
  • Then, remove the grid cover as it’ll expose the defective bin thermistor. 
  • Now, use the screwdriver to remove the defective part and install the new bin thermistor.
  • Finally, put everything back together, and it’ll work perfectly. 

Remove Scale From Your Ice Maker

If you consider going through professional cleanings regularly, you can prevent scale in your ice maker. Moreover, when you’ve got hard water in your area, a phosphate filter or a water softener can help you decrease the amount of scale.

Set The Proper Temperature In Your Ice Maker

If the temperature is too low, you just need to turn the temperature in the ice maker to the proper temperature setting. The FDA suggests keeping your freezer temperature at 0° F (-18° C).
