With the improvement of residents' economic consumption level, the popularity of freezers and cold storage is getting wider and wider, and everyone's demand for freezers is gradually increasing. However, in our daily use process, more or less there will be use failures, mostly due to Our operation is not standardized and daily maintenance is not in place. Here are some common failures and related solutions:

(1) The compressor starts frequently: if the power supply voltage is too high, it should be stopped immediately. After the power supply voltage returns to normal, it should be restarted. Start the compressor and check whether it returns to normal. If it still cannot work normally, contact relevant after-sales personnel for on-site maintenance;

(2) The indicator light is on normally, but the compressor does not work and emits a "buzzing" current sound. The machine should be shut down immediately. If the local voltage fluctuation range often exceeds the specified range and is unstable, an AC voltage stabilizer should be installed. After the power supply voltage returns to normal, start up and check the effect;

(3) There is no frost on the surface of the freezer evaporator, and the compressor runs for a long time: the pipeline is damaged and leaks, and the refrigerant leaks. Contact professional after-sales personnel for maintenance;

(4) The surface of the evaporator is frosted, and the compressor is running continuously:

① Too many times of opening and closing doors of the freezer;

The placement of the wrong position, not enough ventilation, heat dissipation position or dust and other impurities attached to the above, resulting in poor ventilation, heat dissipation effect;

③ temperature control controller failure or temperature bag from the evaporator, resulting in evaporator frost;

Treatment method: defrosting should be carried out in time to clean up dust and other impurities on the condenser and compressor. Sufficient positions should be left around the freezer and not close to the wall. If the thermostat fails or the temperature sensing bag is detached, the after-sales master should be allowed to repair or replace it;

(5) Compressor does not work:

① If the power indicator light is not on, the power fuse is blown, and the fuse must be replaced;

② The indicator light is on normally, which is a circuit failure of the controller. You need to contact a professional maintenance master for on-site inspection and maintenance;

③ Temperature controller weak file environment temperature is too low, adjust the temperature properly.

Note: The above several common freezer failure problems, if there are other failures or will not operate, should promptly contact the product after-sales personnel, do not operate at will, to avoid unnecessary equipment damage.
