Haier refrigerator and freezer issues can create major problems and may even lead to food loss. If you find that your Haier freezer or refrigerator is not keeping food at the right temperature, it’s essential to address the problem as soon as you can. The good news is that many of the issues that cause refrigerators and freezers to be too warm can be fixed by following a few easy troubleshooting steps. We’ll discuss the most commonly cited causes of warming refrigerators and freezers of Haier and provide step-by step solutions. We can assist you in getting your refrigerator and freezer at the right temperature, regardless of whether you’re an expert DIYer or newbie.
Cold Control or Temperature Control
The cold control is a temperature-controlled switch that supplies power to the compressor and fan circuits in the refrigerator. The cold control may be inaccurate or defective if the fans and compressors aren’t functioning properly. The typical fresh food temperature is within the 38deg F range with the control set to the mid-point. Verify that the capillary tube or sensing bulb has not been damaged or out of place and also that wire terminals are not damaged or loose.
Unplug your Haier refrigerator prior to beginning. Then, open your Haier refrigerator’s door and find the control. It’s located inside the control for the fresh foods section panel, usually behind the knob for temperature adjustment.
Remove the control from the appliance and then turn it to the most warm setting. Then, set your multimeter to Rx1 so that it can connect to the terminals.
The probes are being tested for continuity. You should get an infinity reading. If the probes are still touching the terminals, adjust the control to higher (colder) and higher settings. The reading should be changed to zero, which indicates that there is continuity.
If your control fails either of the above tests it will require a replacement Haier cold control & temperature control.
Motor for Evaporator Fan
When the compressor is operating When the compressor is running, the Haier fan motor is circulating the cool air through the refrigerator. The fan could stop working and temperatures in the fresh food and freezer sections will increase slowly. In the event of this it will cause the compressor to be more frequently and for longer than normal. With the compressor running it is also possible to be able to hear the evaporator fan roaring at the same time, as well as the condenser fan which is located next to the compressor.
How do I inspect a Haier refrigerator evaporator fan motor:
Connect the Haier refrigerator from the power source . Then remove the cover of the evaporator It is located in the freezer compartment.
The motor shaft should rotate without resistance. try turning the shaft by hand to check for resistance.
If you notice a large amount of ice on the motor, defrost your freezer and check whether that solves the issue. Also, you should inspect the motor for signs of wear or damage.
If it is not turning easily or is noticeably worn, you need a replacement Haier evaporator fan motor.
Electronic Control Board
Certain models that are more recent in Haier refrigerators may use an electronic control board. Thermistors , also known as temperature sensors, are linked to the control board and are used to check temperatures in freezer and fresh food compartments. The control board makes use of this information to control the operation of the compressor, fan motors, and defrost systems. If the temperature is too hot, the electronic control is at fault. Haier electronic controls are complex and costly and are usually reliable. Therefore, you must first check that all the other components , including the compressor, the fans and sensors are functioning properly prior to condemning the control. Manufacturers could have specific details that will help you determine the cause of the problem with the control.
How to verify the control board electronic on the Haier refrigerator
Remove the plug from your refrigerator prior to starting since you’ll be handling electrical components.
Locate the electronic control board and remove it from your appliance. It’s in the Haier refrigerator. The control box is located on the top of the fridge.
Examine your control board for indications of damage, such as burnt, wear connections or arounging.
It is necessary to replace the Haier electronic control boards if you notice any of these signs.
Temperature Sensor or Thermistor
A thermistor, also known as a temperature sensor, is employed in models equipped with the feature of an Electronic Control to monitor the temperatures of fresh food items and frozen food. The sensor is a tiny capsule that is secured by a protective plastic shield and has a resistance that varies depending on the temperature. The control board utilizes this information to switch on the fan and compressor circuits as well as to manage the damper control on some models. If a sensor gets damaged or defective , it can not correctly signal the control board to turn off the compressor and fans and cause warmer temperatures than normal fresh food or freezer temperatures. The manufacturer may have information specifically for testing the sensors, based on the type of sensor. Some models may even have fault codes for the electronic control boards.
How do you test a temperature sensor in a refrigerator or thermistor using a multi-meter:
Begin by disconnecting the Haier refrigerator. After that, remove the back panel to reveal the main control board.
The thermistor(s) will be connected to the main control board. To test the thermistor(s) take it off from the appliance.
It is recommended to check them by placing the thermometer(s) in freezing water for five minutes to raise the temperature to 32°F.
If you connect the probes to the terminals, and the multi-meter set to Rx1 and Rx1, you should see a reading of 16,600 ohms (+/- 5 percent).
If you see a temperature reading that is outside of this range, you’ll require an replacement temperature sensor from Haier or the thermistor.
The defrost-timer is an electronic timer. It is controlled by a set of contacts that control the heater and compressor circuits. The majority of timers activate the defrost cycle after 8-10 hours during compressor run time. It usually happens once each day or twice. The defrost timer should terminate the defrost cycle after 20-30 minutes, and the compressor and fan will then begin.
How to test a defrost timer in a refrigerator using a multimeter:
Find the defrost timer you need by disconnecting your appliance from its source of power. You can find it on the lower side of the refrigerator’s kickplate or in the control panel on the Haier refrigerator. It may also be behind the refrigerator’s back wall.
If you find it, pull the timer for defrost off of the appliance to check it.
Make use of a multimeter that has the Rx1 setting. One probe should be placed on the common terminal. (It must be marked as “3” or C). The other probe is to be connected to the remaining three terminals, one at a time. Test the first pair and result in a reading of or near zero indicating continuity. The reading of zero or near zero could also be reported by the second pair. Testing the third terminal is likely to yield a reading that is infinity.
If you don’t receive these readings you will require a replacement Haier defrost timer.
The Haier safety thermostat, which is attached to the defrost heater can be utilized to stop the defrost process at a certain temperature. It is usually rated between 38-47 degrees Fahrenheit. If the thermostat is defective and remains open circuit, then the defrost heater will not be powered up and defrosting won’t happen.
How do I test the thermostat of a refrigerator’s defrost using a multi-meter
Unplug your Haier refrigerator and locate the refrigerator’s thermostat for defrost. For models with a top freezer it can be found beneath the floor of the refrigerator or located at the back of the freezer. If you have a tandem refrigerator, the thermostat that controls defrost is located at the back of the freezer’s side.
When you’ve found it, you must remove the thermostat that controls defrost to check it. It is necessary to take out any obstructions in the way, like the freezer’s contents, freezer shelves as well as icemaker components, and the back, rear, or bottom panel.
Adjust your multimeter to the Rx1 setting. Each probe should be positioned on an electrical wire for your thermostat. If your thermostat is not cold, the multimeter should show zero. If the temperature is warmer (anywhere from forty to ninety degrees Fahrenheit), then this test should yield a result of zero.
If your results from your test differ from the ones that are presented, you’ll need a replacement Haier thermostat.
The defrost heater is the appliance that melts the ice and frost out of the evaporator coils. It’s usually a wire filament wrapped in glass or aluminum tubes. There may be more than one heater depending on the form of the evaporator.
How do I test the refrigerator’s defrost heating element using a multimeter:
Make sure you’ve removed your appliance from its electrical source before you begin.
Locate your defrost heater. It can be located behind the back panel of the freezer section of your Haier refrigerator, or on the floor of your refrigerator’s freezer section. Defrost heaters are commonly located below the evaporator coils in a refrigerator’s. It is necessary to clear them of any obstructions, including the contents, freezer shelves, icemaker pieces, as well as the back, bottom, or the bottom panels.
Before you are able to test the defrost heater to test it, you need to remove it from your refrigerator. Two wires join to a defrost heat source. They are joined using slip-on connectors. Make sure you grasp the connectors using a strong grip and then remove them from the terminals. You may need an plier with a needle-nosed to help. Don’t pull on the wires.
The multi-meter is a great tool to check the continuity of the heater. Set your multi-meter to the Rx1 scale and connect the tester’s leads on one of the terminals each. The reading should be anywhere between zero and infinite.
If you get a reading of zero or infinity, you will need a replacement Haier defrost heater.
Motor for condenser fans
Most modern frost-free Haier refrigerators will have condenser coils that are fan-cooled. It is usually located close to the compressor located at the bottom rear of the refrigerator. The condenser fan circulates air around the condenser coil in order to eliminate heat. If your Haier refrigerator is more warm than normal and the compressor is operating in a continuous manner, then you might have a problem with the motor for the condenser. The motor for the condenser runs simultaneously with the motor for the evaporator and the compressor. The compressor will be running almost continuously even if the fan motor ceases to turn.
How to examine the motor of a refrigerator’s condenser fan:
Begin by disconnecting the Haier refrigerator to the power source and then remove the rear access panel to locate the condenser fan motor. It’s typically located on the bottom of the appliance.
Once you’ve found it, check for debris or obstructions that could hinder the fan from free movement. You should also inspect the condenser motor for indications of wear or damage..
You’ll need an new Haier condenser motor in the event that the motor has been damaged or worn out.
