What are the common problems of Haier refrigerator?
First, the refrigerator leaks 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.
Second, the refrigerator door is hot.
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.
Third, the door is 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, tighten the screw with a knife or screwdriver to insert it into the door frame along the gap after adjustment, gently pry up the decorative cover, and tighten the fixing screw to embed it into 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.
Fourth, the refrigerator crackles.
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.
The above are the common faults of Haier refrigerator shared by Bian Xiao. I hope it helps you.
