Analysis of five common faults of display cooler and their treatment methods
The rapid development of the refrigeration industry, the use of display cooler naturally becomes more and more popular. When using the display cooler, failures are inevitable. How to find them in time The most fundamental thing is to deal with the cause of the failure. The following refrigerated showcase display cooler recommends some common display cooler failures and solutions.
1. Fault phenomenon: The power indicator light is on, the compressor is not working normally, only a buzzing sound.
Cause of occurrence: The power supply voltage is too low and exceeds the prescribed lower limit.
processing method: stop immediately, and restart after the voltage returns to normal. If local voltage fluctuations often exceed the specified range, an AC voltage stabilizer above 1KLA must be installed.
2. Failure phenomenon: The compressor starts, stops within one minute, waits a few minutes to restart, and so on.
Reason: The power supply voltage is too high and exceeds the specified upper limit.
processing method: stop immediately, and restart after the voltage returns to normal. If local voltage fluctuations often exceed the specified range, an AC voltage stabilizer above 1KLA must be installed.
3. Failure phenomenon: The compressor has a long running time and the evaporator surface is free of frost.
Cause: There is a leak in the pipeline, and the refrigerant leaks. The pipeline is blocked.
processing method: send it to the maintenance department for overhaul.
IV. Fault phenomenon: There is frost on the surface of the evaporator and the compressor does not stop running.
Causes of occurrence: too many times of opening the door, or poor heat dissipation from the condenser, poor ventilation; failure of the thermostat or the evaporator due to the temperature sensor bulb detached from the evaporator, resulting in too thick frost on the evaporator.
Treatment method: In this case, we must defrost in time and prescribe the right remedy. For example: the condenser does not dissipate heat well, and the dust on the condenser and compressor can be cleaned when the ventilation conditions are not good; and the temperature controller is encountered. If it is out of order or the temperature sensing bulb is detached from the evaporator, it must be sent to the maintenance department for repair.
5. Fault phenomenon: the compressor does not work.
Cause: The fuse on the power supply is blown (the power indicator is off); the control circuit is faulty (the power indicator is on); the temperature of the temperature controller is weak and the environment temperature is too low.
Treatment method: but the fuse must be replaced when the fuse is blown; the control circuit failure (power indicator light is on) should be repaired by maintenance personnel. If the temperature is not up to the point, just adjust the temperature.
The above are the permanent faults of the display cooler and the troubleshooting methods. I hope it can help you use the display cooler.
