A freezer does not provide much value if it does not keep the temperature below freezing. So, if you have opened your freezer door and found a mountain of melted items, you are now wondering why my freezer stopped working.

If your freezer isn’t keeping things frozen properly, start by checking the temperature settings to ensure they’re right. Look over the door seal for any damage and think about replacing it if needed to maintain a tight seal. Giving the condenser coils a thorough cleaning can also help improve cooling efficiency. But if you’ve done all that and the problem persists, it could indicate a bigger issue like a faulty compressor or low refrigerant levels that need expert attention.

Below you can find the full list of possible problems and symptoms and some remedies to those problems. 

Freezer Not Freezing

There can be any number of reasons why your freezer is not cold enough. If the reason the freezer is not freezing is as simple as the door being left open or the thermostat being turned down, those problems obviously can be fixed quite easily.

If there is, however, an issue with some of the parts in your freezer, the solutions can become more complicated.

Dirt and Debris in Vital Parts

The condenser coils for a freezer can reside in two locations. If the condensing coils on your freezer are located inside the unit, they do not require cleaning.

However, if the condenser coils are located outside your unit, they should be cleaned at least every six months. If the coils have become dirty, they are less effective at dissipating heat, thus significantly reducing the cooling capacity and may be the reason for a freezer not cooling

Another issue you may face is evaporator coils that are frosting over. In a typical system, the defrost heater will turn on many times during the day to melt away this frost.

If the defrost heater is not turning on, frost accumulates on the coils and will not function properly. When this happens, your freezer will not operate properly. 

Problems With Mechanical Parts

Your freezer uses a variety of fans and coils to create freezing air. When these parts are damaged or inoperable, that can lead to freezer temperature problems.

One possible issue can be a faulty evaporator fan motor. If the fan is not working, the freezer will not cool. 

One great way to check for this problem is to open your freezer door and manually activate the freezer door switch. If you activate the switch and the fan does not operate, the evaporator fan motor may be the culprit. 

Another issue may be a faulty condenser fan motor. Without this fan, the condenser can overheat and will not work properly. If you find the condenser fan is spinning freely, but it’s still not operating, chances are you need to replace the condenser fan motor.

A faulty compressor is the last mechanical part of the freezer that can be an issue. This is the pump that circulates the refrigerant through both the evaporator and condenser coils. 

Unlike the fans, this is the least likely culprit when encountering problems; however, if the fans operate normally and your freezer is not getting cold, it may be time to replace your compressor

Problems With Electronic Parts

In addition to the mechanical parts of your freezer, your unit has several electronic parts. Since these items often regulate the operation of the mechanical parts of your freezer, they obviously need to be in good working order.

If your freezer is not cold, one issue may be a faulty start relay for your compressor. This relay provides power to the compressor so that it will run properly. If the start relay is faulty, the compressor will only intermittently run or may not run at all.

Another problem may be the temperature control thermostat. This item controls the voltage to the compressor, condenser fan motor, and evaporator fan motor. If this thermostat is inoperable, those systems will not get power, which may be why the freezer is not getting cold.

Your freezer also contains several control and display boards as well. While these items rarely break and are usually not a cause of a problem, if all other systems have been checked and you have found no faults, these boards may be the culprit causing an inoperable freezer. 

How To Solve Freezer Temperature Problems

Now that we’ve shown you some of the reasons for a freezer not cooling enough let us show you how we can help you solve some of these issues.

Check the Simple Things First

So, is the unit plugged in? While that may seem simple, it is not uncommon when a unit is being moved for cleaning, for example, that it is unplugged and not plugged back in.

Maybe the freezer door is not closing completely. When this happens, freezing air is simply rushing out the door, and the freezer compartment does not stay below freezing.

Check Your Mechanical Parts

Look at your evaporator coils on the back of the freezer and ensure there is no dust or debris there. Ensure that all the fans we mentioned can turn properly with nothing getting in their way.

If you suspect that any of the motors for the fans are faulty or that your compressor has failed, this is something you can repair on your own. These parts can easily be found online or at any appliance store.

While you can do this on your own, be forewarned that this is a somewhat complicated job that is usually best left to professionals. We feel confident in saying that the pros here at FIX Appliances CA can do this job much more quickly than the average homeowner, and the job will be done right the first time.

Solving the Electronic Parts Issues

All the electronic parts of your freezer are probably the least likely to fail, yet they can be the most challenging to repair. Go through the steps we outlined above to ensure none of those things are the problem; if they are not, your electronics may be the culprit.

Electronic parts can easily be found online or at an appliance store like mechanical parts. Unlike the mechanical parts, the electronic parts can be difficult to install and configure correctly.
