Sub-Zero Refrigerator Ice Maker Problems
Sub-Zero Refrigerators are renowned for their top-tier quality and innovative features, but even these high-end appliances can encounter issues from time to time. In this blog, we’ll explore common problems associated with Sub-Zero Refrigerator ice makers and provide solutions to keep your ice supply abundant and refreshing.
Ice Maker Not Producing Ice
- Check the water filter. If it’s been a while since you changed the filter, the mesh may have become clogged with mineral deposits, blocking water flow through the unit. For best results, Sub-Zero recommends changing the water filter every 6-12 months, depending on usage. Do make sure you’re buying certified Sub-Zero water filters—there are many counterfeit refrigerator water filters online, and not only do they perform less well, some are even made of toxic materials.
- Check that the ice bucket is correctly placed. If you’ve removed the ice bucket, be sure it was replaced correctly. The ice maker only switches on when there is contact between the bucket and the electronic switches at the back of the fridge.
- Check that the ice level arm is in the down position. The arm is white, wide and flat and is situated above the ice bucket when the freezer is closed (note: freezer trays are removable for easier access). If it’s up, shut off the freezer and gently push the arm down. If it won’t budge, don’t force it, as you may break it. Once down, restart the unit. If the arm has become disconnected, it may have to be reinstalled or replaced if broken (in which case, call us, we sell replacement parts and can also handle the repair for you).
- Check whether the fill tube is frozen. If the arm is down, next check the fill tube. The fill tube is a thin tube located above the ice maker, coming from either the back or side wall. Low water pressure can allow the water in the fill tube to freeze, preventing flow to the ice maker. If it feels especially stiff, turn off the unit and use a hair dryer on low speed to melt the obstruction. When using a hair dryer, be sure to move the dryer back and forth to avoid melting the plastic piping.
- Check that ice isn’t obstructing the exit from ice maker. Sometimes ice cubes will stick together if the freezer door has been opened repeatedly in a warm kitchen, obstructing the ice’s exit from the ice maker. Grab that hair dryer again, and set it on low, and pass the warm air over the clumped ice until the pieces separate easily. After freeing obstructions, turn the unit off and then on again to reset. To prevent ice buildup like this in the future, we recommend emptying the ice bin monthly.
- Check the water supply lines. Water supply may be obstructed by a kink in the water line, readjusting the line to remove the kink may solve the problem. There may also be an inadvertent separation of the water line connection. (The latter will probably be signaled by a water leak on the kitchen floor.)
Slow Ice Production
If you’ve noticed a decrease in ice production from your Sub-Zero refrigerator’s ice maker, several factors could be at play. Ensure that the water supply to the refrigerator is connected and providing sufficient water pressure. Low water pressure can slow down ice production. Check if your refrigerator’s water filter is due for replacement. A clogged or outdated filter can impede water flow, affecting ice production.
Small or Misshapen Ice Cubes
Ice cubes that are smaller than usual or misshapen can be indicative of a problem. The water inlet valve may be malfunctioning, causing it to release insufficient water to fill the ice mold completely. A faulty valve can result in smaller or deformed ice cubes.
Cloudy or Odd-Tasting Ice
If your Sub-Zero refrigerator is producing cloudy or ice cubes with an unusual taste, consider the following solutions. Poor water quality can lead to cloudy or strange-tasting ice. Ensure that your water source is clean and free from contaminants. You may want to invest in a water filtration system if needed. Additionally, regularly clean the ice maker and the ice bin to prevent the buildup of impurities and residue that can affect ice quality.
Does Your Sub-Zero Refrigerator Temperature Fluctuate? Here’s Why…
Why does your Sub-Zero Refrigerator temperature fluctuate? You’re probably wondering if this is normal or if there is a bigger problem with your refrigerator.
A Guide To Why Your Sub-Zero Refrigerator Temperature Fluctuates
Knowing the ins-and-outs of your refrigerator is essential to maintaining this type of high-end appliance. That’s why we made this easy-to-use guide to help you better understand what’s normal behavior, and when your Sub-Zero may need to be serviced.
What Temperature Should My Sub-Zero Refrigerator Be Set To?
Your Sub-Zero Refrigerator temperature setting should be set to 38°F. While you can set the temperature lower or higher depending on your preferences, a temperature above 45 degrees is not safe.
According to the FDA, food stored at temperatures above 45°F for more than two hours will spoil. Warm food means mold and bacteria growth that can cause foodborne illnesses and foul smells.
Is It Normal For My Refrigerator Temperature Fluctuate?
Yes, it’s perfectly normal for a Sub-Zero Refrigerator temperature fluctuate. Temperature changes between +/- 5°F are to be expected.
A new refrigerator’s temperature fluctuates as it reaches its desired temperature setting, and can take up to 24 hours to stabilize. Other influences include the level of humidity and external room temperature. Even everyday actions like opening and closing the door can cause fluctuations.
If you’re noticing major refrigerator temperature problems though, there may be a more significant issue. Any fluctuations over +/- 5°F may lead to unwanted freezing in your refrigerator or food spoilage.
Why Is My Refrigerator Temperature Fluctuating?
So what problems cause your refrigerator temperatures to fluctuate? Simple solutions include making sure your refrigerator door closes properly. Clear any food or objects that won’t let to door close and seal correctly. A lack of food or new food also raises the temperatures in your refrigerator. Add more food or water bottles and allow a few hours for the temperature to stabilize.
Does your Sub-Zero Refrigerator temperature fluctuate still? Dirty condenser coils may be the issue. The condenser is what removes heat from your refrigerator. If the coils are dirty, heat can’t escape properly.
You can easily clean the condenser coils on your Sub-Zero Refrigerator yourself:
- Unplug your refrigerator from the wall or turn off its circuit breaker.
- Remove the grille and use an appliance brush and vacuum to remove dirt and dust.
- Replace the grille and allow 24 hours for the temperatures to return to normal.
If neither of these tips solves the problem of extreme temperatures in your fridge, it’s time to get a professional in to service it. Sorting out minor problems as they happen saves you money before a minor inconvenience turns into a major repair job.
