There are also some icing phenomena at the drainage hole, which makes the defrosting water unable to be discharged. This situation is either caused by the low temperature setting of the refrigerator, so it is appropriate to adjust the temperature setting of the refrigerator between 4-8 degrees. If it is a mechanical thermostat, just turn down the digital file.
If the temperature of the refrigerating room is within the normal range, it is the quality problem of the refrigerator, which is caused by the poor foaming quality of the insulation layer at the drain hole or the coil is too close. During the warranty period, the manufacturer may be required to return or exchange goods.
During the warranty period, the back should be repaired after the sale, the drainage pipe should be rearranged, foamed away from the freezer, and finally installed with the backboard. This is the most effective maintenance.
After the warranty period, the system can be modified. The method is to find a thick power cord, peel off one end to expose the core, cut off the power supply of the refrigerator, move the refrigerator, remove the protective cover under the back of the refrigerator, then pull out the water tank on the compressor, and insert the core of the power cord upward from the drain hole on the compressor until it is exposed from the drain hole of the refrigerator. The other end of the power cord bypasses the installation position of the water tank, peeling off the skin for a long time, and then tightly winding the wire core on the high-pressure pipe on the right side of the compressor for several more turns. Then install and reset the water box. In this way, when the compressor works, the high temperature of the high-pressure pipe is conducted to the drain hole of the refrigerating chamber through the power cord, so that it will not freeze, so that the defrosting water can be discharged smoothly without water accumulation.
