YTE is committed to ensuring the continuous and efficient operation of your dehumidifier. We provide a comprehensive fault analysis and repair guide, including troubleshooting sequences for ventilation systems, electrical systems, refrigeration systems, and other common issues, as well as corresponding repair strategies and recommendations.

1. Troubleshooting Sequence for Dehumidifiers Not Dehumidifying:

  • Ventilation System Faults: Check the intake and exhaust grates, air filters, evaporators, fan motors, and blades for blockages, damage, or wear.

  • Electrical System Faults: Inspect the power supply, switches, sockets, voltage, circuit breakers, fuses, and the operation of compressors and fans.

  • Refrigeration System Faults: Examine for refrigerant leaks, system blockages, excessive refrigerant, and compressor displacement issues.

  • Compressor Faults: Diagnose compressor efficiency issues, including high and low chamber gas leakage and damaged operating parts.

2. Troubleshooting Sequence for Increased Noise in Dehumidifiers:

  • Inspect machine balance, loose parts, foreign objects, damaged fan blades, starter faults, and collisions in the piping.

  • Diagnose issues related to lack of oil in the fan, bearing faults, excessive noise from the compressor, and problems caused by too much refrigerant or lubricant.

3. Troubleshooting Sequence for Dehumidifiers Leaking Water onto the Floor:

  • Check for imbalances in the placement of the dehumidifier, excessive tilting of the water collection tray, blockages in the drain hole or pipe.

  • Inspect for damage to the water collection tray, leaks at the water pipe connections, or aging and cracking of the water pipes.

Fault Phenomena and Repair Methods:

  • Rapid shutdown and poor dehumidification: Check the air speed at the vent and the resistance of the fan motor. Replace the damaged fan motor.

  • Normal operation but low dehumidification: Inspect the evaporator and refrigerant for leaks. Empty the refrigerant, repair the leak, and refill.

  • Frost on the surface of the low-pressure pipe: Check for blockages or leaks in the capillary tube and filter. Replace the filter and refill the refrigerant.

  • Decreased dehumidification and increased power consumption: Inspect the evaporator, condenser, and compressor. Replace the compressor.

  • Gradual decrease in performance over time: Clean the evaporator fins, investigate and repair refrigerant leaks.

  • Power on, compressor runs but the fan does not: Check the fan's electrical circuit and motor. Eliminate electrical faults or replace the fan motor.

Through this comprehensive guide, YTE hopes to help you better understand and maintain your dehumidifier. If you encounter any problems during use, please contact our professional repair team.
