Don’t let these many culprits confuse you. In fact, a proper fix of some of these issues may automatically resolve other problems. For instance, troubleshooting bad thermostats may fix some compressor issues.
So without further delay, let’s take a deep dive into the most common sneaky components and find suitable fixes.
Remember: Unplug your Haier refrigerator before attempting to troubleshoot any of its internal parts.
1a- Problematic Thermostat
In all Haier fridges, a thermostat plays two crucial roles: regulating the refrigerator temperature and activating the compressor. Thermostat troubles don’t go unnoticed. You can suspect a faulty thermostat if you find the following signs:
- The fridge is too warm or too hot regardless of temperature settings.
- The compressor drops dead or keeps running non-stop.
1b- How To Fix Problematic Thermostat
In most cases, a problematic temperature control thermostat needs retirement and correct replacement. But sometimes, minor issues can trigger thermostat malfunctions. For accurate diagnosis and proper troubleshooting, do the following:
- Reset the fridge: The resetting trick never gets old. In some cases, it can effectively resolve sudden glitches in different components. Try unplugging your fridge for a few minutes, then plugging it back in. This attempt can jolt the thermostat back to life.
If the problem persists, move to the next steps.
- Locate the thermostat: In most, if not all, modern appliances you can find the thermostat behind a panel inside the back wall of the refrigerator compartment. You’ll need a screwdriver to access this part.
- Clean to restore coolness: Dust and debris can cling to the thermostat. If the surface becomes full of these blockages, they act like insulators, preventing the component from functioning correctly. You can use a piece of cloth, a vacuum cleaner, or a brush to clean it.
- Tighten loose wires: Loose connections disrupt communication between the thermostat and the compressor. You can wiggle the wires to determine where looseness lies. Then, retighten them using pillars. In case you are not familiar with handling electrical wires, it’s better to call in a pro.
- Test before you toss: Use your multimeter to check the thermostat resistance at different temperatures. Consult your owner’s manual for test instructions and recommended reading. If the readings aren’t within the specified range, install a new thermostat.
2a- Defrost Issues
Your fridge goes through defrost cycles to prevent frost buildup. During each cycle, the defrost heater warms things up, melting accumulated ice. But when this smooth operation malfunctions, frost takes over, blocking airflow and hindering your fridge’s ability to cool effectively.
When you notice defrost problems, you can blame different parts of the defrost system, such as the defrost timer, defrost heat, or sensor.
The timer controls these cycles. Once it malfunctions, the heater may not activate, leaving your Haier fridge feeling like a deep freezer.
As for the temperature sensor, it’s responsible for triggering the defrost cycle. When it becomes defective, you will find continuous frost buildup.
2b- How To Fix Defrost Issues
Since many parts are causing defrost problems, the fix requires many steps as the following:
- Force a defrost: Many of the latest appliance models offer the option of forced defrost. Check the manual to ensure whether your fridge has this function. Push the button to kickstart the cycle.
If your fridge lacks this feature, no worries. You can defrost manually using the old unplug and clean trick.
- Inspect the timer: Find this component in the freezer compartment, which requires emptying it from food and shelves. Look for the timer behind the front grill or inside the control panel. Refer to the manual for the exact location.
- Activate the timer: Plug the fridge back in and turn the timer’s knob until you click. Then, check on the compressor, which is supposed to stop running once you set the timer.
- Check the heater: After this troubleshooting process, wait for a half an hour. Then, take a look at the heater. If it’s warm, congrats you fixed the problem. If not, you should get a new heater.
- Inspect the sensor: If the heater is cleared, check the sensor. Unplug the fridge again and look for the temperature sensor on the underside of the evaporator. It appears like the letter “U” and is attached to a plastic clip.
Disconnect it from its wiring and bring a multimeter to test for resistance. Use the manual for testing instructions and expected reading. Replace the sensor if the readings are inconsistent.
3a- Ice Maker Issues
Ice maker defects are not the most common reasons behind your Haier refrigerator not cooling properly. However, when this component becomes faulty, your fridge won’t produce and dispense ice correctly.
By understanding the potential causes of ice maker defects, you can troubleshoot and fix them more easily. Some common causes of ice maker defects include:
- clogged water filters
- faulty water valves
- incorrect thermostat settings
- ice stuck in the mold
A troublesome ice maker may reduce the ice supply, cause water leaks, or increase the energy consumption.
3b- How To Fix Ice Maker Issues
Troubleshooting this part of Haier appliances requires accessing the top compartment of the freezer. Look for it on the back wall towards the right side. Use a screwdriver to remove any screws in the way.
- Free the water filter: While not all Haier fridges don’t have a water filter, if yours has one, it should be cleaned regularly. In case cleaning doesn’t resolve the issue, you should replace it.
- Check the water inlet valve: Find this valve behind the kickplate at the bottom front of your fridge. If this plate has holding screws, remove it with your screwdriver. Inspect it for kinks or blockages. You can try to straighten minor kinks manually. However, severe blockages or damages require replacements.
- Inspect the fill valve: Find this valve near the water inlet valve. This part controls the water flow to the ice maker. Sometimes, this valve malfunctions due to insufficient water flow. You can try this toolless hack to revive this valve. Turn off your fridge’s water supply at the source, then turn it back on after 30 seconds. If this doesn’t resolve the problem, then you should replace it.
- Clean & reset: While at it, remove debris from the ice maker to free any blockages obstructing the water flow. Check the manual to identify the reset buttons for the icemaker.

4a- Compressor Problems
Think of your Haier refrigerator’s compressor as your car’s engine. The compressor pumps the refrigerant through the coils to create cold air that keeps your food freshness.
When this component malfunctions, there is potential formation of warm air pockets, compromising the cooling efficiency and the food quality.
Here are a few causes behind common compressor issues:
- Insufficient refrigerant levels
- Faulty or overworked compressor
- Blocked or dirty condenser coils
- Electrical issues or power surges
- Faulty thermostat
To be certain the compressor is responsible for your Haier refrigerator not cooling efficiently, you can perform these simple diagnostic tests. You can listen closely to the noises coming from the compressor’s direction (located at the back of the fridge). Unusual humming or clicking noises can indicate compressor trouble.
Another test you can do is touching the compressor with bare hands. If it’s warm to the touch and not running, it could be a sign of trouble.
4b. How To Fix Compressor Problems
While DIY solutions for compressor issues exist, they often require professional attention. Tampering with electrical components can be dangerous. Don’t hesitate to seek help from a qualified technician. Here are a few DIY solutions:
- Check power supply: Sometimes things are too simple. So, ensure your fridge is not disconnected from the power source and that the power outlet is functioning correctly.
