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.
Store an ice cube or two in a sealed plastic bag or small container in the freezer; a sealed bag/container is important so the ice cube doesn't evaporate and disappear. If the ice cube has melted down from its original shape, you'll know the power was off for an extended period of time.
Compressor Sounds: When the freezer is running, listen for a humming sound from the compressor. If it's silent or making clicking noises, it could indicate a problem. Fan Operation: Check if the interior fan is running. If not, it may be a sign of an issue. Ensure the thermostat is set to a cold enough temperature.
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.
If your freezer isn't maintaining its set temperature or not freezing items at all, it's likely broken. Unusual noises, excessive frost buildup, or a malfunctioning display panel can also indicate a problem.
Problems with the freezer's electronic control board, cold control thermostat, defrost timer, or compressor can all result in a freezer that does not run or runs improperly.
- If the coin is still resting on ice, freezer did not lose power and food quality was not compromised. - If the coin is now sitting at the bottom of container, or submerged below water, the freezer's internal temperature may have become warm enough to compromise food.
A full freezer will hold a safe temperature for approximately 48 hours (24 hours if it is half full and the door remains closed). Food may be safely refrozen if it still contains ice crystals or is at 40°F (4°C) or below, however, its quality may suffer.
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.
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.
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.
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.
A failing compressor is not something to be taken lightly. Left untreated, it can lead to more serious issues, like food spoilage or even a complete breakdown of your refrigerator.
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 the environment is too cold, the freezer may not get sufficient run time to maintain its temperature. If the temperature is too warm, the appliance will have a hard time getting the interior down to the desired temperature. Dirty condenser coils or a broken fan motor can also cause insufficient freezing.
Walking through the steps of resetting a freezer should only take a few minutes, but it can take up to 24 hours for the freezer's temperature to stabilize upon resetting. Freezers that were only briefly disconnected should reach the desired temperature sooner.
How long can you leave a freezer unplugged? A freezer that remains unused for more than a year may develop some issues. To counteract this, consider running the freezer periodically, even if it's empty. This practice helps maintain an optimal internal temperature and prevents the compressor from becoming stagnant.
