If your chest freezer isn't freezing, the issue usually stems from a power failure, poor air circulation, a bad door seal, or a mechanical malfunction like a failing compressor.
To quickly fix a chest freezer that isn't freezing, ensure it is securely plugged into a working outlet, check that the temperature dial is set to the coldest setting (often 444 or 555), and clean the rubber door gasket to ensure a tight, frosty seal.
First, cut power to your freezer by unplugging it from the wall or shutting off power to the proper control panel switch. Then reset the freezer's control panel by lowering it to zero or using a shut-off switch.
If your freezer isn't freezing, Mr. Appliance recommends these troubleshooting steps:
Chest freezers typically last 12 to 20 years, with an average lifespan of about 16 years. Because their design is highly mechanical and they are opened less frequently than upright models, they often outlast standard kitchen refrigerators.
It depends on the situation if it makes more sense to repair or replace a freezer. If the seal is bad on a chest freezer, spending $100 to repair it is worth it. But if the compressor goes out in your older and cheaper upright freezer, buying a new model may make more sense.
Putting a penny (or any coin) in the freezer is an easy trick used to check if your freezer lost power while you were away, and whether your frozen food is still safe to eat.
Types of Common Freezer Problems
To reset a freezer compressor, disconnect the unit from power (unplug or flip the circuit breaker) for 5 to 10 minutes. This clears system faults and allows internal pressures to equalize. Restore power, then verify the temperature controls are properly set.
The national average price to have a freezer repaired ranges from $100 to $400. The average homeowner spends around $200 to repair an upright freezer with a broken seal. Replacing a light bulb in a simple chest freezer is about $50, but fitting a built-in drawer freezer with a new compressor can cost up to $650.
Most freezers do not have a dedicated, physical "reset" button. Instead, you can reset the freezer's internal computer or clear system errors by performing a hard power cycle. Unplug the freezer for 5 to 10 minutes, then plug it back in to reboot the system.
Green = Run. The green run light indicates the compressor is running. If the indicator is dark it does not mean the unit is off. The compressor only runs when the compartment temperature is too high.
When a chest freezer suddenly stops working, it is usually caused by a power interruption, an issue with a mechanical component, or a cooling system failure.
There are two sound signs of a faulty compressor.
One is that it often makes strange or loud noises, such as clicking, clacking or humming, which are not common during normal operation. The other is that there is no running sound, which indicates that the compressor is not working.
To reset a chest freezer, unplug the unit entirely or turn the temperature dial to "0" (or "Off"). Wait 5 to 10 minutes for the internal electronics to recalibrate and the compressor's internal pressure to equalize, then plug it back in and set it to the desired temperature.
A freezer that stops freezing is typically caused by restricted airflow, a bad door seal, dirty coils, or a failing evaporator fan. These are the most common culprits and usually the easiest to troubleshoot yourself:
The reset button is almost always located on the electric motor itself—usually on the side or back near the terminal box. It typically sticks out as a small rubber-covered or exposed black/red button, sometimes labeled "Circuit Breaker".
A bad air conditioning compressor struggles to pressurize and circulate refrigerant. The most common symptoms include warm or lukewarm air from the vents, loud grinding or squealing noises when the AC is on, the compressor clutch failing to engage, and repeated tripping of your home's circuit breaker or car's AC fuse.
A compressor replacement is probably worth it if the refrigerator is less than 8 years old, is a high-end make or model, and is in otherwise good condition. Skip the repair if the cost is more than 50% of what the fridge is worth.
Both upright and chest freezers can last an average of 10 to 15 years. To make your freezer last longer and live its best life make sure the unit gets proper ventilation, don't overload it with food and keep it set at a consistent temperature. Do some maintenance, too. Yes, freezer maintenance is real.
Take a bottle of water, empty about half of the water and put it in the freezer on its side. Once frozen put it in the door upright. If the water is every at the bottom, then the freezer was off and you should probable replace the perishable items .
A freezer can often be repaired if it's not cooling properly, and in many cases, the issue is related to a simple fix or a faulty component that can be replaced. "We had this exact problem with ours- it was the heating element for the condenser, which is behind the back cover of the freezer."
