Have you ever opened your freezer for a frozen treat only to notice that nothing is actually frozen? Your freezer is running, but for some reason, nothing inside is freezing properly!

You're not alone; this problem happens more often than you think. But don't worry, there are several potential reasons why this is happening — and your local experts at are here to help!

Let's explore some of the common causes of why your freezer isn't freezing and get things back on track!

1. Temperature Setting Issues

One of the simplest reasons your freezer might not be freezing is incorrect temperature settings. It’s easy to overlook and can easily be caused by accidental brushes against the control, but setting the temperature too high can prevent your freezer from doing its job. And luckily, there are simple ways to fix it!

Check Temperature Setting: Make sure the freezer temperature is set to 0°F, the optimal temperature for freezing.
Adjust the Settings: If it’s set too high, lower it and give your freezer about 24 hours to stabilize and see if it starts freezing correctly.

Pro Tip:
If adjusting the temperature didn’t fix it, the problem might be a faulty thermostat, control board issues, or a damaged temperature sensor. But don’t worry, our service team can handle those!

2. Dirty Condenser Coils

Another common reason your freezer might be running but not freezing is dirty condenser coils. These coils play a crucial role in the cooling system by dissipating heat. When they get covered in dust and debris, they can’t function properly, causing your freezer to struggle to maintain cold temperatures.

So, locate the condenser coils, usually at the back or underneath the freezer, unplug the machine, and use a vacuum or brush to remove the dust and debris. After plugging it, it should start freezing correctly.

3. Faulty Evaporator Fan

The evaporator fan is crucial for circulating cold air throughout the freezer. If this fan isn’t working correctly, the cold air won’t distribute evenly, leading to a freezer that runs but doesn’t freeze as it should.

Listen for Unusual Noises: Strange noises can signal that the evaporator fan is malfunctioning.
Check the Fan: Open the freezer door and manually inspect the fan for any obstructions or damage.
Replace the Fan: If the fan isn’t working properly, it may need to be replaced to ensure proper air circulation.

Pro Tip:
Checked the fan, and it’s still not working? There might be an underlying electrical issue or a fan motor problem, but you’ll need the experts (aka us!) to take a look!

4. Defrost System Problems

You might not think it, but a freezer full of frost can also be a freezer full of thawed-out food. And if your freezer is experiencing this, it’s because all that frost buildup has coated your evaporator coils and blocked the cold air from circulating! This makes your freezer ineffective!

So, if you open your freezer, check the evaporator coils (usually located behind a panel inside the freezer) and see if there’s frost all over it. If that’s the cause, try defrosting it manually or with the defrost setting!

Pro Tip:

5. Door Seal Problems

Did you know something as simple as the door seal could be the culprit behind your freezer not freezing? The door gasket, which seals the freezer shut, is vital for keeping the cold air inside, so if it’s damaged, the cold air escapes and your freezer has to work harder to maintain the correct temperature!

Inspect the Door Gasket: Check the gasket for any cracks, tears, or signs of wear. A damaged gasket can't seal properly, allowing cold air to leak.
Perform the Dollar Bill Test: Close a dollar bill in the freezer door and try to pull it out. If it slips out easily, the seal is weak and likely letting cold air escape.
Replace the Door Gasket: If you find any damage or if the dollar bill test indicates a weak seal, it’s time to replace the door gasket. A new gasket will ensure a proper seal, keeping the cold air inside where it belongs.

Extra: Inadequate Airflow

As with any part of your cooling unit, airflow is everything. If the cold air can’t circulate freely, some areas might not freeze properly and cause problems. But usually, this is caused by overloading the freezer or from a larger item blocking the vents (just because you can close the door doesn’t mean everything fits appropriately!).

So, make sure to rearrange the contents of your freezer to allow proper airflow, which should do the trick. However, if that doesn’t fix it, you might have an issue with your internal airflow system (which is a job for our team!).
