The fan in the freezer, known as the evaporator fan, is responsible for pulling air from the freezer compartment and passing it over the cold evaporator coils to cool it down. It then circulates this cold air throughout the freezer and to the refrigerator compartment to maintain consistent, even cooling.
It might sound strange to think but a freezer shouldn't run all the time because if it does it will actually build-up to much ice. This can make your freezer to cold and will make opening it and then closing it a problem, it will also be sure to put more stress on the motor.
A properly functioning freezer fan is essential for maintaining consistent cold temperatures. If your freezer fan isn't working, you may notice uneven cooling, frost buildup, or even thawing food. The fan helps circulate cold air throughout the freezer, ensuring everything stays frozen.
The evaporator fan circulates cold air from the freezer coil throughout the appliance. If it stops running, refrigerant flow feels ineffective as cold air doesn't distribute properly.
Types of Common Freezer Problems
Unplug first: Always disconnect power at the wall outlet or breaker before touching the compressor or internal components. Wait it out: Leave the refrigerator unplugged for 5–10 minutes to allow the compressor to fully reset.
A good starting point is the middle setting (for example, 3 or 4). You can use a freezer thermometer to check the temperature and adjust it gradually. Small tweaks are better than large jumps to avoid over-cooling and wasting energy.
8 Signs Your Refrigerator is Dying
7-Signs Your Freezer Isn't Running Efficiently
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.
Your freezer is almost always making noise, but most of the time it just fades into the ambient sound in your kitchen. The constant hum of the unit becomes something you get used to hearing so much that you don't even notice it. That's why it can be so jarring when your freezer is making a loud buzzing noise.
Normal Cycling Patterns
So, how often should a fridge/freezer cycle on and off? On average, most refrigerators run for about 45 minutes to an hour before taking a break. This means the compressor is actively cooling your food for around 80–90% of the day.
The following are nine signs your refrigerator compressor could be failing.
Refrigerators need adequate ventilation to dissipate heat effectively. If the refrigerator is tightly surrounded by cabinets or walls, the compressor and fan may run continuously to compensate.
The recommended freezer temperature to keep your food safe is at or below 0°F (-18°C), but your freezer may need to be set higher or lower depending on its environment and other factors. The typical freezer factory setting on Whirlpool® Refrigerators is a great starting point at the recommended 0°F (-18°C).

Freezer problems and possible solutions
By placing a sealed envelope in the freezer, you're essentially creating a controlled environment that encourages the adhesive to contract. As the adhesive shrinks, it often creates micro-fractures along the bond, making it easier to gently pry the envelope open without tearing the paper.
You may have heard of it: Freeze a cup of water solid, set a coin on top of the ice, and put it back in the freezer. The idea is that if your power goes out while you're away and the freezer warms enough for the ice to melt, the coin will drop down into the cup.
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.
Step #2: Unplug your refrigerator
This is normal so don't be alarmed. Tip: Always wait several minutes before attempting to plug your refrigerator back in as the compressor requires sufficient time to fully power down and reset itself.
