Clicking sound occurs when the freezer is cooled: clicking sound or other low-frequency sound occurs when the freezer is cooled. Fault analysis: It is mostly caused by the vibration of the compressor, and it is caused by the vibration between the compressor and the bottom plate or between the refrigerator and the refrigeration pipeline. Troubleshooting: According to your own maintenance habits, handle it in the following ways. Generally speaking, the place where clicking sound is eliminated or reduced by touching is caused by its vibration.
① Adjust the direction of the damping block installed on the exhaust pipe.
(2) Stick damping cement on the top of the compactor as far as possible, and adjust it constantly to find the orientation.
③ Adjust the tightness of the tightened four fixing bolts (usually need to be slightly loosened).
④ Plastic seal the air return pipe and exhaust pipe.
In the process of refrigeration, it sometimes creaks: in the process of refrigeration, the freezer sometimes creaks. Fault analysis: it is more common in refrigeration models under upper refrigeration. The reason is that the refrigeration evaporator expands with heat and contracts with cold, which should be attributed to normal phenomenon, but it should be cleaned as much as possible. Troubleshooting: slapping the freezer 1 ~ 5 times on the evaporator can generally eliminate the creaking sound.
When the machine is started or stopped, it suddenly makes a huge metal crash: the refrigeration share and the start or stop time are normal, and only when it is started or stopped will the compressor make a huge metal crash. Fault analysis: most of the problems are the height of the four legs of the freezer, and some of them are internal problems of the compressor. Fault repair: according to the following process.
Try to tilt the refrigerator slightly. If the problem disappears, reposition the refrigerator.
② Try to adjust the height of the four legs of the compactor.
(3) Open the shell of the compactor and adjust the elastic force of the internal tension spring to make it uniform.
The body of the injection compactor is hung on the upper shell or installed on the seat spring with a tension spring. If the tension spring is unevenly stressed, the compressor will oscillate instantly when working and stopping, so that the machine body and casing will collide and produce noise. In addition, the oscillation of the high-voltage coil in the compressor will also produce noise at the moment of working and stopping. The electric fan of the indirect cooler is noisy: the electric fan is noisy and the others are normal. Fault analysis: most of them are incorrect fan motor devices, and a few are fan motor problems. Troubleshooting: If the fan motor cannot be replaced, try to adjust the direction of the fan first.
