Midea Fridge Not Cooling – How to Fix

If you find that your Midea fridge is not cooling, take a look at the following:

1. Voltage Supply

Be sure that the supply of power to the fridge is sufficient. Check the voltage that comes to the fridge using a multimeter. You should see between 110v to 120v. Any voltage less than these means the fridge will not work well. And if it doesn’t work well, it will not cool. Simply fix the outlet or move the fridge to another part of the house where the supply is better.

Also, ensure the fridge’s power cord is in good working condition. If it is frayed or damaged in any way, the fridge may stop cooling. Thoroughly inspect it for burn signs or other damage and replace it if necessary. Arrange the power cord so that the fridge does not rest on it. Tie it in a loop and tape it to the back of the fridge if it is too long.

2. Fan Motors

Check both the condenser fan and evaporator fan motors. If they are defective, the fridge will not cool. Test them using a multimeter to check for continuity.

You can also check the blades for obstructions to the condenser fan motor. If anything is obstructing them, they won’t turn. And if they don’t turn, the compressor will overheat and end up not running well.

For the evaporator fan, test the motor windings for continuity. If there is no continuity, the motor is bad and should be replaced. Also, listen for any strange noise coming from it. That will let you know something is wrong with the motor. Change it as soon as possible.

The evaporator fan is in the freezer section, behind the rear wall inside it. That means you must remove the freezer contents, including the shelves and bins, where applicable. Ice may obstruct the fan and stop it from circulating the cold air from the evaporator coils. So, be prepared to melt ice if that is the problem.

On the other hand, the condenser fan is usually at the bottom back of the fridge, next to the condenser coils and compressor. Since it is exposed in the most neglected part of a fridge, it is not strange for the fan to become clogged with dirt.

Dirt can restrict the blade and cause overheating, which affects the fridge’s cooling capacity. Thoroughly cleaning the blade can resolve the fan problem instead of replacing the fan motor.

3. Coolant

If the coolant or refrigerant is short, it will not be able to cool the air that flows through the evaporator coils. Consequently, the fridge will not have enough cool air to operate optimally. Fortunately, this problem is rare, so it may not be the reason for the lack of cooling in your Midea fridge.

However, you will be unable to check the coolant’s level, as the process is too technical. There may be a leak in the refrigerant lines or coils, causing the refrigerant to leak. But only a qualified appliance technician should troubleshoot and fix the problem. So, contact a qualified technician or call the support center of Midea to check it out.

4. Start Capacitor

Test the start capacitor for continuity with a multimeter. If you don’t see any continuity, the start capacitor is bad and needs a replacement.

Without a functioning start capacitor, the compressor will not start, and the fridge will not run or cool as it should.

5. Start Relay

Test the start relay between the start and run terminal sockets using a multimeter. If there is no reading, then you know the relay is bad.

Another way to ascertain this is to remove it from the compressor and shake it. If you hear a rattle, the relay is bad. In addition, if you smell any burnt odor, the relay is bad and should be replaced immediately. This is because without it, the compressor will not run.

6. Thermistor

Check the thermistor’s resistance in conjunction with the fridge’s temperature by testing it with a multimeter. If the resistance does not change as the fridge’s temperature changes, the thermistor is bad.

Without the thermistor, the control board of the fridge will not be able to send voltage to the compressor and evaporator fan motor to operate as they should. So the fridge will not cool.

7. Thermostat

Turn the thermostat’s knob from the lowest point to the highest point. Wait to hear a click. If you don’t hear this click, the thermostat is broken and should be changed. Without the thermostat, the fridge’s temperature could be stuck at one point, causing the fridge not to cool as it should.

In some cases, the fault could be with the compressor. You can check if the compressor is running by listening to hear its humming sound. If you don’t, it is possible it is not running at all.

The problem could also originate from the main control board. Check with a professional repairer to be sure it is the problem because it rarely is.
