1, the cause of the failure: induction leakage. Solution: As the compressor control circuit and cabinet lighting circuit are from the cabinet shell and the inner wall through, there is a certain distribution capacitance, the compressor with induction motor in the rotation of the self-induced potential, people may touch the cabinet have a numb feeling, which should be connected to the grounding wire, so that the cabinet is reliably grounded.
2, the reason for the failure: refrigerated display cabinet body is not well grounded. Solution: the refrigerated display cabinets on the shelf with rubber wheels or wooden rubber and other insulators, the shelf should be removed to ensure safety.
3, the cause of the failure: the power cord due to insulation plastic deterioration, moisture, wear and tear makes the insulation layer was damaged. Solution: At this time, you should promptly update the power cord.
Extended information:
Other faults of refrigerated display cabinets.
1, "running" and "alarm" light flashing: mainly for the refrigeration system failure, such as refrigerant leakage, ice, dirty blockage, etc.; but also for the fan blade is stuck or motor leads off and poor contact.
2, "H" and "E" and "alarm" light flashes: mainly for the temperature sensor breakage, short-circuit or failure failure, which is the "E" for the temperature sensor breakage, short-circuit or failure. "E" is the freezer sensor failure; "H" is the freezing or greenhouse sensor failure.
3, freezer gear "high, low" and "alarm" flashing: this is the freezer damper failure. This refrigerator uses electric air door, driven by a stepper motor. Mostly due to motor drive part of the problem; and then in place switch failure, signal break, or poor contact wire card; a few bad motor.
4, the greenhouse gear "refrigerated", "micro-frozen" and "alarm" flashing: this is because the greenhouse damper failure.
