Two screens flash E0: indicating that the refrigerating room and the freezing room are out of order at the same time.
The alarm display E0 in the temperature change zone indicates that the sensor of the temperature change chamber is faulty, so replace the sensor of the temperature change chamber.
This problem can be solved by replacing the thermostat.
Extended data:
First, Haier refrigerator fault code analysis:
1, the "Run" and "Alarm" lights are flashing.
Mainly the failure of refrigeration system, such as refrigerant leakage, icing, dirt blockage and so on. There are also problems such as fan blades stuck or motor leads falling off and poor contact. The "H", "E" and "Alarm" lights are flashing: the main reason is that the temperature sensor is open, short-circuited or invalid, where "E" indicates that the sensor in the refrigerator is faulty; "H" indicates that the sensor of the freezing or changing greenhouse is out of order.
2. The gear position "high and low" of the refrigerator flashes together with "alarm"
This is a malfunction of the refrigerator damper. This refrigerator uses an electric damper and is driven by a stepping motor. Mostly because of the problem of motor driving part; Then the in-place switch failed, the signal was broken, and several motors were broken. The gears such as "cold storage", "slight freezing" and "alarm" of the variable greenhouse flash together: this is because the damper of the variable greenhouse has failed.
Second, the common fault analysis:
1. Does the refrigerator leak to the surrounding ground?
There are two reasons for water leakage: frost on the air return pipe of the refrigeration system, and the compressor turns into water dripping on the ground after stopping. In this case, the amount of dripping water is small, and the water on the ground is in a state of infiltration. The reason is that the refrigerant in the refrigeration system is charged too much after maintenance. Please ask professional maintenance personnel to discharge and maintain an appropriate amount of refrigerant.
The second is that the defrosting drain pipe of the refrigerator is not inserted into the water pan, and the nozzle is outside the water pan. In this case, you can check the drain pipe from the back. If the drain pipe is too long, cut off a section and cut the nozzle into an inclined plane to facilitate dripping, so that the push-pull tray will not collide with the drain pipe again, and the water leakage fault will be eliminated.
2. Is there a fever near the refrigerator door?
The high-pressure pipes of the compressor are all around the door frame, and the heat of the high-pressure pipes is used to avoid condensation, so it is normal for the door to heat up. The temperature rise of refrigerator compressor unit can reach 95℃. As long as the automatic start-stop of the refrigerator works normally and the refrigeration in the box is good, the whole machine is no problem. Combustion of compressor unit is normal. ?
It is normal for the refrigerator to make a strong vibration sound when it starts and stops. There are white powdery substances and sometimes patina at the welding part of the refrigeration system pipeline of the refrigerator. This is not refrigerant leakage, but powder deliquescence after solder powder absorbs moisture. Wipe off and coat with black paint.
3. Is the door not straight?
In this case, just adjust the door hinge to make the door straight. Just loosen the lower hinge screw of the single-door refrigerator, adjust the position of the door body, and then tighten the screw. Loosen the middle hinge screw of the double-door refrigerator, move the door body left and right, and make adjustments.
Tighten the screws, and then insert the skeleton along the gap with a knife or screwdriver. Lever up the decorative cover gently and forcefully, and then tighten the fixing screws to embed the decorative cover. The deformed part of the door seal can be heated and shaped by hot air with a blower, and then shaped after cooling to achieve good sealing performance. You can check it with a flashlight.
4. What is the crackling sound of the refrigerator?
One is that the louver condenser bursts when the condenser expands with heat and contracts with cold, and the other is that the water on the evaporator forms thin ice after refrigeration begins. With the acceleration of freezing speed, thin ice cracks and makes noise under the action of freezing stress. Everything is normal. When the refrigerator is running, the sound of airflow in the pipeline and the slight rushing sound of frozen oil in the compressor are all normal sounds.
In winter, the ambient temperature is very low. The temperature difference between the inside and outside of the refrigerator is very small, and even the temperature outside the refrigerator is lower than that inside the refrigerator. It's not the fault of the refrigerator. As long as the knob of the thermostat is turned to the high gear, the unit can run normally and everything meets the requirements. In addition, the compensation switch in the refrigerator can also be turned on to help the refrigeration unit start running.
