Necessary strategy for checking freezer before use

Check the refrigerator door seal: First check the door seal, because the door seal directly depends on the power consumption and heat preservation effect of the refrigerator, and also affects the service life of the refrigeration compressor. Good quality door seals have good suction force, and when the electric refrigerator door is opened, there is obvious resistance. If not, the quality of the door seal is not good. Compressor: see if high efficiency compressor is used. Compressors are very important, just like human hearts, and are also the main energy-consuming components in freezers, freezers and refrigeration equipment. Using high-efficiency compressors is the simplest and most effective measure for freezer energy saving. Check the condenser: After the freezer runs for a few minutes, touch the electric freezer condenser with your hand. There should be obvious thermal sensation, and the faster the heat is, the better, while the air return pipe has obvious cold sensation. If there is no cold feeling, the performance of the electric refrigerator is relatively poor. If there is frost on the return pipe, it means that the cooling is too much, the power consumption is not large, and the cooling effect is not very good. Check the commercial freezer of the freezer: Check whether there are cracks and wrinkles, especially whether the excessive original angle is smooth and whether the thickness of the inner plate is uniform. When checking the refrigerating chamber, it is necessary to pay attention to whether the temperature controller rotates flexibly and whether the defrosting button can rebound back quickly when pressed. Power-on trial: After the above inspection, it can be powered on for trial operation, adjust the knob of the thermostat to a certain position, connect the power supply, and check whether the lamp switch and bulb are normal. At the moment when the power is turned on, attention should be paid to the starting performance of the compressor and whether it can be started at one time.
