Are you tired of opening your refrigerator and finding your Sub-Zero refrigerator freezing food? It’s frustrating, right? You had everything set to the perfect temperature, and yet, somehow, your lettuce is frozen solid. Fear not, dear reader, for we are here to solve this chilly conundrum.

Troubleshooting a Sub-Zero Refrigerator Freezing Food

Why is your Sub-Zero refrigerator freezing your food? It’s not that your fridge is trying to play a cruel joke on you (even though it might feel like it).

Why Is My Refrigerator Freezing Everything?

There are a few reasons why your fridge is freezing your food, let’s dig into them here:

  • Temperature: It’s possible that the temperature is set lower than needed, making your Sub-Zero fridge too cold and causing everything in the fridge to turn into a block of ice.
  • Airflow: If the air isn’t circulating correctly, then some parts of the fridge might be colder than others.
  • Thermostat: Your thermostat might be malfunctioning, causing the temperature to drop lower than what you set it to.
  • Condenser coils: Dirty or clogged condenser coils can cause your fridge to work harder than it needs to, leading to colder than desired temperatures and frozen food.

How to Stop Your Sub-Zero Refrigerator From Freezing Your Food

So, now that we’ve identified the problem, let’s talk about the solutions to each of these problems here:

  • Adjust the temperature: Make sure the temperature is set between 38-40 degrees Fahrenheit, if it’s below that you may experience freezing.
  • Check the airflow: Is anything blocking the vents in your fridge? If so, move those things out of the way. You can also try rearranging the food in your fridge as well as keeping the fridge less full to allow better air circulation.
  • Check the thermostat: If the temperature is still too low, even after adjusting it, then it might be time to call a professional to replace your thermostat.
  • Clean the condenser coils: Wondering how to clean Sub-Zero condenser coils? It’s a pretty easy task. You can clean your condenser coils by unplugging your fridge and using a soft brush or vacuum brush to remove any dust or debris.

Common Sub-Zero Refrigerator Part Issues

In addition to the issues listed above, there are a few common Sub-Zero part issues that can cause your Sub-Zero refrigerator freezing food:

  • Damaged door gasket: A damaged door gasket can let in warm air, which can cause your fridge to work harder than it needs to and lead to colder than desired temperatures. If it’s really dirty that can also cause problems, you can learn how to clean a fridge gasket on our blog!
  • Faulty defrost timer: If the defrost timer is faulty, your fridge might not go through its defrost cycle properly, leading to ice buildup and frozen food.
  • Malfunctioning thermistor: The thermistor senses the temperature inside your fridge and sends a signal to the control board to adjust the temperature. If it’s malfunctioning, then the temperature inside your fridge might be lower than what you set it to.
  • Faulty fan motor: The fan motor circulates the cold air throughout your fridge. If it’s not working properly, some parts of your fridge might be colder than others, leading to frozen food.
