Food that won't stay frozen may be an obvious sign of a faulty freezer, but signs like excessive frost build-up on the walls or freezer-burnt food can also indicate unstable freezer temperatures. You may also notice your freezer making unusually loud humming, clicking or buzzing noises as parts struggle to operate.
Just put a thermometer in the freezer and take a peek at it every time you open the door. The maximum temperature is 0° F, if it is above that you need to reset your thermostat. A good range to keep the freezer temp. is -5° to -10° F.
Cause: The freezer may not be receiving power due to a blown fuse, tripped circuit breaker, or unplugged cord. Fix: Check the power supply, reset the breaker, replace fuses, or ensure the freezer is plugged in. Cause: Airflow can be obstructed by items stored too close to the vents.
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
Freezers typically last anywhere from 12 to 20 years. Along with gas and electric ranges, freezers tend to be the longest-lasting kitchen appliances. But that's not a guarantee! Many factors influence how long freezers last, including maintenance and environmental factors.
Be sure to check the electrical outlet, thermostat and airflow around vents. Cooling problems can also be caused by dust on condenser coils, faulty gaskets, clearance space around the refrigerator, a broken or stuck condenser fan or a faulty circuit board.
Turn off the refrigerator and freezer from the control panel. After unplugging the refrigerator, turn off the fridge and freezer using the control panel inside the fridge. To do so, set the controls to “zero" or switch them off entirely. Once you're done, you can plug your refrigerator back into the wall socket.
Place hot water (in bowls or glasses) inside your freezer section of your appliance, making sure you have plenty of towels and a suitable container for the water that will be created from thawing ice. Wait for the freezer to defrost. This can take several hours.
You Hear Unusual Noises
A hum or a slight buzz is typical, but if your refrigerator starts making strange or loud noises, the compressor might be struggling. Professional Repair Required: Compressors have numerous components, and diagnosing the source of the noise can be complicated.
If your freezer stops cooling but the refrigerator compartment works, the freezer may have frost build-up or clogged venting preventing it from doing its job. Check the venting in the back of the freezer to make sure no items are resting against it, then examine the ice build-up inside the freezer.
Wait several minutes, then plug the freezer back in and restore power to the control panel switch. Set your freezer to your preferred temperature settings and allow it to cool. It can take up to 24 hours for its temperature to stabilize, depending on how long the unit was without power.
Clear blocked air vents: Inspect the air vents inside the fridge and freezer compartments to ensure they are not obstructed by food or containers. Proper air circulation is vital for even cooling. Check the door seals: Inspect the rubber gaskets (door seals) around the refrigerator and freezer doors for damage.
If at all possible, wait until power is restored before opening the freezer door. If your freezer is full, it will keep items frozen for about 48 hours. If the power will be out less than 24 hours, do not open the door when power resumes. Let your food items refreeze at least 24 hours before opening the door.
Resetting your refrigerator compressor really only consists of unplugging or disconnecting power from your unit, waiting, and reconnecting, with a few other steps. You should also ensure that your fridge hasn't accidentally been put into a display mode, meant for showroom units.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
Fill a small cup with water and place it in the freezer. Once the water is completely frozen, place a penny on top of the ice. If you return from vacation and find the penny still on top, your freezer's contents remained frozen, and your food should be safe.
Faulty Evaporator Fan
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.
Signs that Your Freezer is Dying
Spoilage – A properly functional freezer will keep the foods in good condition for a long time. If the food starts rotting before its expiration date, the freezer isn't working efficiently and needs repairs.
There is no need to replace your freezer if you are able to diagnose it properly. Sometimes, the fixes are simple and can save substantial money. The most expensive repairs involve replacement of the pricey components, such as compressor, control board, or thermostat.
Once you start noticing freezer burn, frost build up or clumps of ice in your freezer, then you should know that your freezer is no longer functioning properly. Your fridge may have an issue with the temperature. It may be getting too cold or may be warming up and then cooling down.
