Midea Freezer Not Freezing – Solution
The first thing to check is the temperature setting. Sometimes, you may set the wrong temperature or accidentally adjust it. As simple as it sounds, wrong temperature setting is one of the primary reasons a freezer stops freezing as it should. So, ensure the setting is correct and make adjustements where necessary.
However, if the freezer is still not freezing after adjusting the temperature to a lower setting, here are things to do:
1. Check the Evaporator Fan Motor
To determine if the motor of the evaporator fan is faulty, open the door of the freezer and activate the door switch by pressing it. When you open the door, the evaporator fan motor stops running. But when you press the switch, the motor starts running again.
However, if pressing the door switch does not get the fan motor running again, it means the motor is bad and you should consider replacing it. Replacing the fan motor can be complex if you have never done it before. So, use the services of a technician if you are unsure of the steps.
The evaporator fan circulates cold air in the freezer after passing it over the evaporator or cooling coils. If the motor of the fan is faulty, the fan won’t operate and the freezer won’t freeze.
2. Check the Start Relay
The start relay combines with the start winding to power the compressor of the freezer or fridge freezer. If the start relay is defective, the compressor will find it hard to run or may not run at all.
Test the start relay by connecting a multimeter between the start and run terminal sockets to check for continuity. If there is no continuity, replace the start relay. In addition to that, if there is burnt odor coming from the relay, replace it.
Some mechanical relays allow you to test them by simply shaking them and listening for a rattling sound. If the relay from your Midea fridge does not rattle when shaken, you can go ahead and run a continuity test as explained above to be sure. However, if it rattles, you do not need the continuity test to determine whether or not it is defective. Replace the relay as quickly as possible.

3. Check the Condenser Coils
Dirty condenser coils cannot dissipate heat effectively from the unit. This means that the heat from the refrigerant will travel into the freezer and make it hard for the unit to cool or freeze. Dirt acts as insulation that traps the heat, making it almost impossible to release it into the atmosphere. The dirtier the coils are, the more difficult it will be for them to work.
Cleaning the coils is easy to do and should be done regularly, once or twice a year. Use a vacuum brush head to clean it and wipe leftover dust with a soft cloth. If need be, clean sticky dirt or grime with a soft cloth dipped in a mixture of warm water and mild soap. Ensure you clean them once or twice a year.
4. Check the Evaporator Coils
If the cooling coils are frozen stiff with ice, they cannot cool the air that the evaporator fan draws over them. As a result, the freezer will have no cold air in it so it will not freeze.
Open the inside rear panel of the freezer to inspect the evaporator coils. The amount of ice on them will tell you how long they will take to defrost. You can either use a hair dryer or defrost the freezer manually in order to melt the ice.
However, check the defrost system of the freezer to see which of the components is faulty. This is because it is not normal for ice to build on the coils; the defrost heater should warm them once they become too cold.
Test the continuity of the defrost heater using a multimeter. If there is no continuity, replace the heater. But if the defrost thermostat is faulty, it will not be able to sense that the coils are cold. So, it cannot allow the heater to turn on and warm them. Therefore, check the thermostat, too.
Finally, test the functionality of the defrost timer. It should automatically move into the defrost cycle. Use a screwdriver to turn it anti-clockwise until you hear the heater turn on. This tells you that the timer is faulty; you shouldn’t have to manually turn it in before it starts working. So replace it.
5. Check the Temperature Control Thermostat
The motors of the condenser fan and the evaporator fan, together with the compressor, have voltage directed to them by the thermostat. These parts of the freezer cannot work if the thermostat is faulty and cannot direct voltage to them. Consequently, the refrigerant won’t run and the freezer won’t cool or freeze.
Move the thermostat from the lowest temperature setting to the highest temperature setting and wait to hear an audible click. If you hear the click, then the thermostat is likely not faulty. But if you don’t hear the click from the thermostat, test it with a multimeter to check for continuity. If you don’t find continuity, replace the thermostat.

6. Check the Condenser Fan Motor
It is possible the freezer will not freeze, though it may cool, if the motor of the condenser fan is defective. Try spinning the blades of the fan with your hand. If the blades are stiff, the bearings of the motor are worn so the motor should be replaced.
But if the blades of the fan are not stiff and they are not encumbered by any external object, test the motor using a multimeter to check for continuity. If there is no continuity, replace the fan motor.
Let us add that the main control board, the user control, and display board, or the compressor could be defective. This could lead to a lack of freezing problem in the freezer. However, you cannot be sure unless you check them.
But to avoid wrongly diagnosing these parts, contact a qualified refrigerator technician to troubleshoot the parts and fix the problem.
In rare cases, the sealed system of the freezer could develop a leak. This leak could cause the freezer not to freeze because of the loss of refrigerant. If you suspect that there is a leak, we have qualified technicians on hand to help you determine this for sure and advise you accordingly.

Important Note: Ensure you don’t open the door of the freezer too often or leave it open for too long. Doing this will let the cold air in the freezer escape and the warm outside to enter, reducing the cooling capacity of the freezer.
Additionally, the door seal could be loose or weak. Check it to see if it seals tightly and replace it if you suspect it is not sealing well anymore. Also, clean it thoroughly if it is dirty. A dirty door seal will let warm air seep in and compromise the freezing ability of the freezer over time.
Remember to unplug the freezer before testing or fixing any part of it if your Midea freezer is not freezing. If you cannot reach the wall socket, power off the circuit breaker. Doing this will keep you safe from electric shock.
