Fixing the different refrigerator error codes being displayed begins by testing your refrigerator’s sensor. The testing method is simple. You use a multimeter (view on Amazon) that has an ohm switch to get the resistor readings of the sensor. The readings in your resistor should be 2kohm when the temperature is at 25℃. The resistor’s value increases by 45ohm with every 1℃ decrease in temperature. If the readings showing in your multimeter show different readings from the range, it means that your refrigerator’s sensor is faulty and should be repaired or replaced.
Once you have determined the status of your resistor, you can begin solving the error code displayed on the refrigerator screen. Here are the simple fixes that you should use while fixing the fault codes.
E1 Error Code – Refrigerator Sensor Malfunctions
This error is displayed in the refrigerator temperature display area and is caused by faulty refrigerator sensors. This fault code indicates a short circuit or open circuit within the fridge chamber temperature sensor. Inspect the sensor using a multimeter with the ohm switch. Get the resistor of the sensor and compare it with the standard readings. You also need to confirm if the connection is good or not. If the temperature sensor is faulty, you will have to replace the sensor. In the same vein, change the control PCB if it is faulty. If you are not sure about how to do this, contact a refrigerator specialist within your locality.
E3 error code – Freezer Sensor Malfunctions
E3 fault code is caused by a faulty freezer sensor and is displayed on the freezer temperature display area. This fault code indicates a short circuit or open circuit within the freezer chamber temperature sensor. Inspect the sensor using a multimeter with the ohm switch. Get the resistor of the sensor and compare it with the standard readings. You also need to confirm if the connection is good or not. If the temperature sensor is faulty, you will have to replace the sensor. In the same vein, change the control PCB if it is faulty. If you are not sure about how to do this, contact a refrigerator specialist within your locality.
E4 Error Code – Defrost Sensor Malfunctions
When the freezer temperature display area shows the E4 fault code, it means that there is a problem with the defrost sensor. Error code E4 is displayed on the digital display window. It indicates that the evaporator defroster sensor is either an open circuit or has a short circuit. To be completely sure about what has caused the fault code E4 to be displayed on your screen, measure the resistor of your refrigerator’s sensor using a multimeter with the ohm switch. You also need to check the wiring connection leading to the sensor. Compare your readings with the expected readings and, based on the range with which your real reading deviates from the expected, make a determination whether the evaporator defrost sensor is faulty or not. If it is faulty, replace it. If the control PCB is bad, replace it, too.
Fault Code E6
Error code E6 on your Hisense fridge is an indication that your compressor is running hotter than normal due to a dust/hair-clogged condenser coil. You need to check that the components and coils behind it aren’t covered in dust. If this is the case, you’ll need to dust them using a vent hoover or brush. Whilst you’re here, check that the compressor isn’t getting hot. After this, you need to check to see if the condenser fan motor is running. This fan motor pulls in cooler air from your kitchen, across the condenser coil, through the fan itself, then blows it further across the compressor(s). If this fan is not blowing, the compressors won’t get cooled and prematurely shut off during the refrigeration cycle. If this fan is blowing, and the condenser is cleared, you have more serious problems
Hisense Fridge F1 Error
The F1 error indicates that the vent is blocked. You need to check that the door seal has good contact and it doesn’t seem weak. Since the vent might be blocked, you need to check for ice around it to make sure that nothing is impacting the door seal. After this, check that the components and coils behind it aren’t covered in dust. If this is the case, you’ll need to dust them using a vent hoover (view on Amazon) or brush. Whilst you’re here, check that the compressor isn’t getting hot.
The next thing to check is the evaporator for any buildup of frost. This can cause the F1 error to show up. If there’s excessive ice, then you need to fully defrost your fridge/freezer. This will involve unplugging everything and leaving the door open for at least 24 hours. The last thing you need to check for is oil substances. If you notice lots of oil, as well as the compressor, being hot, this will indicate a refrigerant leak which isn’t good. If you notice that everything looks good, then there’s a chance the temperature sensor or control board is damaged.
Hisense Fridge F2 Error
The f2 error code signifies a bad motherboard or control board. To check this, look for any obvious signs of damage to the board first. Along with the f2 error code, you might notice that the control board goes blank and this can be due to the motherboard. To locate the motherboard, look behind the cover on the back of your refrigerator cabinet. To avoid having a failing fridge, make sure to have a motherboard on deck at all times because they do fail a lot.
If you’re receiving the F2 error on your Hisense Freezer, then the cooling fan has built up with ice which prevents it from circulating cold air. To get rid of the built-up ice, you need to remove the panel containing the fan. Then, use a hairdryer to thaw out the ice. You may also notice ice build-up on the drain hole, you can use the hairdryer to get rid of ice here too. Once you’ve screwed the panel back up, make sure the black sealing tape is in position Defrosting the cooling fans and drain hole several times a year can prevent the F2 error from showing up on your Hisense freezer.
If you’re still seeing the F2 error after this, here are some solutions that you can try:
- Switch off the fridge and leave the door open overnight. Switch it back on in the morning. The sensor inside the fridge gets frozen and cannot control the temperature properly.
- Switch off the fridge. Unplug it. At the back of the fridge, clean the large grid with a hoover thoroughly. Because of the dust in the grid, it can prevent the fridge from cooling down and the unit can’t control the temperature in the fridge section.
- Open the fridge and dry the back of the fridge if wet. If there’s ice, wait for it to defrost. Once defrosted, switch it back on and see if the error is gone.
- Switch off the fridge. Unplug it. Empty it. Turn it upside down. Plug it in. Switch it on for 24 hours. Switch it off. Unplug, turn it the right way up and switch on. This will correct the pressure of the gas inside the compressor. Make sure that there are two people on deck for this kind of maneuver.
Hisense Fridge dr Error
dr indicates that the control detects the door is open. To get the door closed so that the dr error goes away, unplug the fridge and clean the door seal, then close it a bit harder than usual and plug it back. If the dr error hasn’t gone, press and hold the top two buttons on the control to unlock it then empty with the door open for around 24-36 hours. Plug it back (expect some water on the floor) and wait for another 8 hours so it gets back to optimum temperature. If you notice that the error still hasn’t gone, it could be the defrost option. You will have to test/replace the temperature sensor with a multimeter and/or defrost heater element to resolve the issue.
Hisense Fridge Error Code h
Hisense error code h is an error for high temperature. You can get rid of it by pushing the temperature setting but it will come back as long as the temperature is too high. To cool it down, try cleaning the coils under the refrigerator using a brush or hoover. If you still have your fridge’s manual, you can refer to it to see what regular maintenance needs to be done to keep your refrigerator cooling properly.
E0 Error Code – Environment Sensor Malfunctions
The E0 fault code is displayed on the freezer temperature display area and denotes a problem in the environment sensor.
E9 Error Code – Ice Maker Sensor Malfunctions
Fault code F9 represents a faulty ice maker sensor, and it is displayed on the freezer temperature display area.
Eb Error Code – Ice Maker Malfunctions
When the freezer temperature display area shows Eb fault code, it means that your refrigerator’s ice maker is broken. If there’s a problem with the ice maker, then you should check the connecting wiring between the mainboard and ice maker and repair if it is broken.
Ec Error Code – Communication Sending Malfunctions
Ec fault code denotes a fault in the communication sending ability of your refrigerator. It shows on your refrigerator’s temperature display area. This error code shows on the digital display window. It means there is a communication problem between the display PCB and the main PCB. This communication breakdown is bad for your refrigerators. Repair it by inspecting the wire terminal. Ensure the wire terminal is okay and not fixed between the display PCB and the main electrical PCB. You also need to inspect the main PCB and the display PCB to ensure they are in their best working condition. If both the display and main PCB are faulty, you need to replace them with a new PCB.
Er Error Code – Communication Receiving Malfunctions
When your refrigerator’s communication receiving abilities is damaged, your appliance displays the Er fault code on its temperature display area.
Fault Code EF
Error code EF shows on the freezer digital display window. It indicates one of two things, either the fan motor has a short circuit, or it is open circuit. Using your multimeter with an ohm switch, measure the resistor of the fan motor. You also need to inspect if the connection is correct. Compare your readings with the expected readings. If your actual reading largely differs from the expected results, your fan motor and control PCB may be faulty. Replace them if they are faulty.
Hisense Refrigerator Blinking Light
If your Hisense fridge has a blinking light, turning it off then on for a long period of time will stop the blinking. Press and hold the top two buttons on the control to unlock it then empty with the door open for around 24-36 hours. Plug it back (expect some water on the floor) and wait for another 8 hours so it gets back to optimum temperature. If you notice that the error still hasn’t gone, it could be the defrost option.
Hisense Fridge Freezer Troubleshooting
There are common problems that you are likely to encounter while using your Hisense refrigerator. This section will help you deal with these issues exhaustively.
Cooling is Not Good Enough
This problem mostly occurs because of gas leakage in your refrigerator. Any gas leak will curtail the proper functioning of your refrigerator. Failure as a result of a gas leak will manifest as lower pressure of liquid cycle system, a lot of noise coming from the outlet of the capillary, hot copper tube of emitting gas, and a gradual decrease in your refrigerator’s temperature.
Fix this problem by locating the point of leakage on the tube. Sometimes the leaking point appears to have oil. Seal the leaking point properly and then vacuum it. Once all this has been done well, recharge the tubes with gas.
Inefficient cooling also occurs when the amount of gas in the refrigerator is more than enough. When a lot of gas is added into the cycle system, the excess gas will take up space of the evaporator, thus reducing the area of heat exchange. This will interfere with the proper functioning of your refrigerator. Fix this problem by switching your refrigerator off for a few minutes. Open the charging tube and empty the tube by discharging the gas inside the tube. Replace the filter and recharge the gas tube. Seal the tube.
This problem can also occur when there is a low working efficiency of the compressor (view on Amazon). Some parts of the compressor may wear out due to age. This forces the compressor to discharge less gas, which affects your refrigerator’s ability to cool. Fix this problem by changing your old compressor to a new one.
Refrigerator Not Cooling
This problem is caused by gas leakage. The gas may be leaking fast or slowly without making a noise. When you cut the charging tube, no gas will come out of the tube. Fix this problem by locating the point of leakage and sealing it. Then vacuum the tube and recharge it with gas.
Hisense refrigerator error codes are an easier route to fixing your refrigerator. However, you have to learn what each code means. Always check this guide to know what to do when your refrigerator shows an error code that you cannot understand. In addition to this, do not hesitate to call a professional repair to fix your refrigerator in case the fault is beyond your abilities. Consider buying a new refrigerator if the fault is too big to repair.
