Haier Refrigerator Not Cooling But Freezer Works – How to Fix
The following components will cause a Haier fridge not to cool while the freezer is working:
1. Evaporator Fan
Check the evaporator fan if your Haier fridge is not cooling but the freezer is working fine. Turn the blade of the fan with your hand. If it spins without any hitch, then the motor is fine. But if it doesn’t spin freely, the motor is bad.
To further determine if the motor is the problem, test its windings for continuity using a multimeter. If there is no continuity, the motor needs to be replaced.
A faulty evaporator fan is the likeliest cause of a Haier fridge not cooling but the freezer works. This is because it spreads cool air over the evaporator coils and also circulates air throughout the freezer. If it is bad, the freezer will remain cold but the cold air will not get to the fridge anymore.
2. Evaporator Coils
Another component to check is the evaporator coils. Open the panel at the back of the freezer to check the coils. If there is frost all over them, then that could be the cause of your Haier fridge not cooling. You will have to thaw the frost manually, by leaving the refrigerator unplugged for a few hours or with a hairdryer.
Evaporator coils that are frosted over will not be able to allow enough cool air to pass through them. So while the freezer could remain cool, the fridge will defrost and get warm quickly.
In addition to the above, frosted evaporator coils means there is a problem with the defrost assembly. One or more of the components are defective and needs changing. The most likely faulty component is the defrost heater. Get a professional repairer to take a look at it and proffer solutions.
3. Air Damper Control
Yet another component to check is the air damper control. Check to see if it is closed or broken. If it is, then it will explain the lack of coolness in the fridge. Have a qualified technician replace it.
The damper control is responsible for letting cold air into the fridge. Not properly opening will cause the fridge to grow warm quickly.
4. Defrost Timer
To check if the timer is faulty, slowly move the dial into the defrost cycle. The compressor should go off while the defrost heater comes on after a few seconds. If nothing happens within 30 minutes, then the timer has a problem. You will have to replace it.
A defrost timer turns the defrost heater on a few times every day. If it is not working properly or at all, it will not be able to send power to the heater. This, in turn, will cause frost to cover the evaporator coils. Consequently, they will not be able to carry cold air throughout the refrigerator.
Other components to check for faults if your Haier fridge is not cooling are:
Defrost Control Board – If the heater is working alright, then the control board could be the problem. It controls the defrost cycle, alerting the heater to defrost the evaporator coils. A defective control board means the coils will have ice and not be able to carry cool air to the fridge.
Thermistor – Check the thermistor with a multimeter for continuity. If there is none, then it needs a replacement. A thermistor reads the temperature of the refrigerator and sends its findings to the control board. If it is not able to do this, the evaporator fan and the compressor will not function well.
Defrost Thermostat – Use a multimeter to check the thermostat for continuity. If you find none when it reaches the lowest temperature within its operating range, then it is bad and needs to be replaced.
A defrost thermostat keeps an eye on the evaporator coils temperature. When the temperature of the coils dip below a set level, the contacts of the thermostat close in order to let power go to the heater in order to defrost the coils. If the thermostat is not able to do this, the coils will become frozen and not carry cool air to the refrigerator.
Main Control Board – Check it for burns or burnt soldered joints that could have occurred during a power outage or surge. However, a bad main control board is rare so is not likely to be the cause of your Haier fridge not cooling.
Haier Refrigerator Running but Not Cooling – What to Do
If your Haier refrigerator is running but not cooling, here is what to do:
1. Check the Power Cord
If your Haier refrigerator is running but not cooling, be sure that the power cord is plugged in. If it is, then check if it is plugged in fully and well. Also, check the power outlet to be sure it is working.
2. Check the Thermostat Control
Ensure the thermostat control is set to the cold setting in your refrigerator. Move it lower if it is and see if the temperature drops.
In addition to the above, frequent adjustment of the temperature settings will affect how easily the refrigerator cools. It takes at least 24 hours for a refrigerator to adjust to a set temperature. So it will take a longer time for the unit’s temperature to drop if you adjust it too often.
3. Check the Gaskets
Take a look at the gaskets to be sure they seal properly when you close the door of the refrigerator. If they don’t seal well, the temperature in the unit will rise continuously and never remain cool.
4. Check the Location
The part of the house where the refrigerator is will add to its full functionality. If direct sunlight hits it every day, it will affect its temperature. Heavy sunlight will cause its temperature to rise, making the refrigerator to work harder to remain cool. This is especially true if it is summertime.
5. Check Its Use
The number of times the refrigerator is opened every day will affect its coolness. Frequent opening of the refrigerator will cause the cool air that should be trapped within to seep out, leaving the unit warm.
Additionally, if you put warm or hot food too often in it, it will a long time to reach a cold temperature. Allow food to grow tepid or cool before putting them in the refrigerator.
6. Check Air Vents
Be sure that the air vents in the refrigerator don’t have items blocking them. And check to see if they are open. It is through the that cold air flows into the refrigerator.
If all of the above is in order, then check the following:
Check the evaporator fan and the condenser fan. Spin their blades to ensure they move without any hitch and that there are no obstructions to their movement. If there are obstructions like dirt, especially for the condenser fan, remove them. But if there is none yet they are not spinning well, check their motors.
Use a multimeter to test for continuity. If there is no continuity, replace them. For the evaporator fan motor, an unusual noise will alert you to a fault, even if the multimeter doesn’t.
8. Condenser Coils
Clean the coils if they are dirty. If the condenser coils, which are under the refrigerator, are dirty, they will no be able to dissipate the heat from the refrigerant as it passes through them. The heat will make the refrigerator unable to maintain the right temperature, causing it to work extra hard to stay cool. However, this will make it grow warm and retain coolness.
9. Start Relay
Use a multimeter to test the relay for continuity if your Haier refrigerator is running but not cooling. You will find it attached to the side of the compressor. If there is no continuity, you need to replace it. The compressor will either not start at all or start and not run with a bad start relay. Then, the refrigerator will not be able to cool or get cold enough.
10. Start Capacitor
With a multimeter, test the continuity of the capacitor. If the capacitor has no continuity, replace it. The capacitor gives a power boost to the compressor when it is starting. If it is unable to do this, the compressor will find it difficult to start. So, the refrigerator will not get cold enough.

Haier Thermocool Freezer Not Cooling – Solutions
If your Haier Thermocool freezer is not cooling, check the following parts:
1. Condenser Coils
Dirty condenser coils mean that they will not be able to cool the refrigerant that passes through them. This, in turn, makes the freezer grow warm. Clean them if they are under the freezer or at the back. But if they are within the walls of the freezer, they don’t need cleaning.
2. Start Relay
With a defective start relay, the compressor will run from time to time or not at all. And this means the freezer will not get enough power to get cool. Check the stat relay attached to the body of the compressor with a multimeter. If it has no continuity, replace it with a new one.
3. Evaporator Fan
Open the door of the freezer and press the door switch. This activates the switch and the fan should run when this happens. So if you don’t hear the hum of the motor, then know that it is bad and needs replacing.
The freezer will not get cool if the evaporator fan motor is faulty. This is because it is responsible for drawing air over the coils and pushing it all through the freezer.
4. Temperature Control Thermostat
Turn the thermostat of the freezer from the lowest to the highest setting. If you don’t hear a sound, like a click, then test it for continuity with a multimeter. If there is none, replace it.
The thermostat is responsible for directing voltage to the evaporator fan motor, compressor and condenser fan motor. These 3 power the refrigerant system and without it, the freezer will not cool.

Haier Mini Fridge Clicking and Not Cooling – What to Do
Check the compressor and start relay if your Haier fridge clicks and does not cool. You may also want to check the condenser. The start relay provides the compressor with the power boost it needs to start and run. If it is faulty, the compressor will make a clicking noise as it tries to run and stops.
Pull the relay out and shake it; if it rattles, it indicates it is defective. However, not every start relay waorks this way, so run a continuty test on it using a multimeter if shaking it does not produce a rattle. Then, replace it if there is no continuity.
But if the relay works well, check the condenser coils. They release heat into the atmosphere so that the refrigerator does not overheat. However, dirty coils cause the compressor to overheat, and when it overheats, it makes a clicking noise. Therefore, clean the condenser and repeat the cleaning process once or twice a year.
If none of the above works, the problem may be from the compressor. A faulty compressor can click as it turns off and on, so have a technician check it and recommend a permanent fix.
A Quick Note
Always unplug your refrigerator from its power source before you begin any repairs or diagnostics. This is a safety measure, both for you and your Haier refrigerator.
And if any part of the repairs gets too difficult, stop and call a professional refrigerator repairer. This may cost you more but will definitely save you time and your refrigerator.
