Many people turn on the commercial freezer when it needs to be used, and turn it off when it does not need to be used. In fact, this is not right, because if the freezer needs to be used again after being out of use for a long time, it will be turned on immediately, and the refrigerator will be turned on immediately. Abnormal operation or non-operation of major components can cause more serious damage to the entire freezer. So what preparations need to be done before the freezer that has been out of use for a long time is turned on again?
(1) Clean the freezer: place the freezer in a ventilated position, open the door/cover of the freezer, and eliminate the peculiar smell in the cabinet environment caused by long-term non-use; clean the freezer liner and freezer seal with warm water with neutral detergent added and the cabinet, wipe the exposed condenser surface with a soft cloth, be careful not to damage the condenser pipeline to avoid the problem of refrigerant leakage;
(2) Check whether the power supply is normal: Check in detail whether the power cord is intact and whether it can work normally, because the power cord of electrical appliances that have not been used for a long time may be short-circuited, aged or damaged by mice, so as to avoid unnecessary It is a safety hazard, so checking the power cord is a top priority;
(3) The chest freezer is idling, and check whether the freezer can operate normally: plug in the power supply to keep the freezer idling for a period of time, and check whether the main functional components can work normally. For example, if your freezer is air-cooled, first check whether the fan is normal. Operation, the normal operation of the fan can ensure that the compressor works at a normal temperature, and can also ensure that the cooling capacity can be evenly and effectively transmitted to all corners of the freezer; secondly, check whether the compressor can operate normally, and any abnormal noise or vibration occurs. , you need to find professional maintenance personnel for further maintenance work.
Note: If you encounter abnormal noise or shutdown, no cooling, leakage and other faults, do not disassemble and repair by yourself, you should ask professional after-sales maintenance personnel to come check and repair, so as not to expand the scope of the fault.
