Why does my freezer run all the time?
Top 5 Reasons Freezer Runs All The Time? The temperature control thermostat directs voltage to the compressor, evaporator fan motor, and condenser fan motor. If the temperature control thermostat is not working properly, it can cause the freezer to run continuously.
Why is my Refrigerator fan not running all the time?
The fan doesn’t always run because it only runs when needed to cool down or maintain the temperature inside the refrigerator compartment—the fan functions to maintain the food’s desired temperature and keep the refrigerator from heating up. – The doors are opened too often, letting cold air out all over the fridge compartment each time it’s open.
Should the evaporator fan run all the time in a refrigerator?
If you understood the refrigerator cycle earlier, you would know that a faulty evaporator fan will prevent cool air from circulating. The evaporator fan is not supposed to run all the time but until the refrigerator reaches a set temperature. However, it runs in combination with the condenser and compressor fan. This is one school of thought.
What should I do if my freezer evaporator fan is not working?
If the door switch is activated but the evaporator fan motor still won’t run, replace the evaporator fan motor. The defrost heater turns on several times throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils. If the defrost heater assembly has burned out, the evaporator coils will frost over.
Is the fan in a freezer supposed to run constantly?
The evaporator fan motor draws air over the evaporator coils and circulates it throughout the freezer. To compensate for the decrease in cooling capacity, the freezer will run continuously in an attempt to keep the freezer cold.
How often does a freezer fan run?

Why does my freezer motor keeps running?
If your frost-free freezer is constantly running, but is not cold enough, there may be an issue with the defrost timer. This type of freezer has a defrost heater to keep frost from building up on the evaporator coil. The defrost timer cycles the heater on when it is needed to defrost the evaporator.
Why shouldn't an evaporator fan run all the time?
Most people believe that the evaporator fan runs all the time. However, others think it shouldn’t because it will use a lot of power. A faulty evaporator fan does not cool the food and defrosts the one in the freezer. The inside is warmer than it should be.
Why does my refrigerator fan run with no break?
When the evaporator fan runs only with the condenser, you save up a lot of power. When the fan runs without any break, it causes air to circulate properly. This will produce an even temperature throughout the refrigerator. This is what some experts believe.
How does a compressor work?
The compressor converts the liquid refrigerant into gas and pumps it into the condenser coils. Here, the fan cools the gaseous refrigerant, and the heat is pumped out of the refrigerator.
What is inside a refrigerator?
Inside the refrigerator are the evaporator coils. The evaporator fan takes the air from the refrigerator. It blows the air into the evaporator coils. The refrigerant, present in the evaporator coils, in turn, gives off cold air to cool the items inside. The compressor converts the liquid refrigerant into gas and pumps it into the condenser coils.

How much does it cost to change an evaporator fan motor?
When the evaporator fan motor changes, it will cost you anywhere between $150-250. It will not break your bank, but surely will be a hit to your monthly budget. So, during your kitchen work, if you noticed the refrigerator didn’t shut off, the problem can lie anywhere.
What is the function of a freezer fan?
The function of the fan is to push (or pull) cool air across the coils connected to the refrigerant pump to cool them down (thus shedding the heat that's pulled out of the inside of the freezer). Once the freezer reaches it's intended operating temperature, both the pump and the fan normally turn off, to save power.
Do freezers shut off when ice is inside?
Once the freezer returned to it's normal operating temperature they shut off again, but since the ice was no longer inside the freezer to keep the temperature down, the outside heat was much more able to seep into the freezer chamber and warm it to the point where the thermostat detected the need to cool it down, and turned them back on again.
