Common Failure And Treatment Of Cake Display Cabinet
- Jan 07, 2018 -

1. Failure phenomenon: the power indicator light is on, the compressor is not working normally, only the hum

Cause: the power supply voltage is too low, beyond the specified limit.

Processing method: immediately stop, after the voltage return to normal, restart. If the local voltage fluctuation often exceeds the specified range, the ac voltage regulator must be installed above 1KLA.

2. Malfunction: the compressor starts and stops within one minute, then starts again in a few minutes, and so on

Cause: the power supply voltage is too high, exceeding the specified limit.

Processing method: immediately stop, after the voltage return to normal, restart. If the local voltage fluctuation often exceeds the specified range, the ac voltage regulator must be installed above 1KLA.

3. Failure phenomenon: the compressor has long rotation and the evaporator has no frost

Cause: leakage of pipeline, refrigerant leakage. Pipe clogging.

Treatment: maintenance department maintenance.

4. Failure phenomenon: the evaporator has frost on the surface, and the compressor is not running

Cause: the number of opening times is too many, or the condenser heat is not good, the ventilation condition is not good; The evaporator is too thick when the thermostat fails or the heat is removed from the evaporator.

Methods: in this case we can do but to defrost cake for storage in a timely manner to suit the remedy to the case, for example, condenser heat dissipation is not good, bad ventilation can clean the dust in the condenser and the compressor; When the thermostat fails or the heat pack is removed from the evaporator, it must be sent to the maintenance service.

5. Fault phenomenon: compressor does not work

Cause: the fuse on the power supply is fused (the power indicator is not bright); Control line failure (power indicator light); The thermostat "weak" file environment is too low.

Processing method: but the fuse must be replaced when the fuse is fused; Control line failure (power indicator light) must be repaired by maintenance personnel. The temperature is not enough to adjust the temperature.

6. Failure phenomenon: excessive noise

Cause: the refrigerator is uneven; Cold cabinet related fastener looseness; There is contact between the system pipes.

Treatment method: the cold cabinet shall be flat, or loose parts shall be tightened, and the contact shall be separated when there is contact between the system pipe.
