No, dehumidifier dehumidification fault maintenance order:
1. The ventilation system failure:
(1) the wind gate and the wind gate: a. artificial aging crack or damage; B. the wind or the wind obstructed;
(2) air filter, blocked by dust or damage;
(3) evaporator: a. evaporator condenser fin dust; B. the evaporator surface ice;
(4) fan motor: a. capacitor damage; B. fan motor holding shaft. C. the rotor shaft and loose; D. shaft bending deformation; E. bearing damage; F. winding burned;
(5) the blades: a. fixed screw loose; B. the fan blades deformation or damage; C. blades dust serious, seriously affect the air volume; D. mini dehumidifier blades is jammed by dust serious phenomenon of blades.
2. Electrical system failure:
(1) compressor, fan does not turn: A. The power is cut off; B. switch is not closed; C. socket bolt; D. the voltage is too low; E. circuit breaker broken; F. insurance tube burn out.
(2) the compressor does not turn, fan turn: a. starter fault; B. capacitor failures; C. overload protection.
(3) compressor, fan operation: refrigeration system failure.
3. The refrigeration system failure:
1) all refrigerant leakage;
(2) refrigeration system jam: a. dirty plugging; B. oil plug; C. welding plugging;
(3) refrigerants too much;
(4) no displacement compressor (failure).
Compressor fault: 4.
(1) compression, high and low pressure chamber gas channeling;
(2) run a damage, compressor shaft.
Second, dehumidifier noise increase fault maintenance order:
1. The surface uneven, dehumidifier place not smooth;
2. Loose dehumidification machine parts;
3. Dehumidifier with foreign body;
4. The fan blades damage or deformation cause of dynamic balance are destroyed;
5. Starter fault;
6. A collision between line;
Fan oil shortage; 7.
Fan bearing failure; 8.
9. The compressor noise is too large;
10. Filling refrigerant or lubricating oil too much, cause fluid.
Third, dehumidifier to ground water fault maintenance order:
1. The dehumidifier placed imbalance, sink excessive tilt, the overflow;
2. Connect the sink drain or the drain plug;
3. Pick up damage leaks sink;
4. The pipe joint leakage or outlet pipe aging rupture.
Four, dehumidifying effect of variation of troubleshooting sequence:
1. Air filter dust serious, airflow obstruction;
2. The outlet obstruction, absorption airflow obstruction;
Fan speed slow; 3.
4. Poor sealing room, outdoor wet air of infiltration;
5. The room area is too large;
6. The indoor moisture content too much;
7. Evaporator finned dust is more, the lower the frozen dehumidification effect;
8. The evaporator surface frost;
9. The evaporator inner product oil, cooling dehumidifying effect;
The refrigerant charge quantity is insufficient;
11. The refrigerant leakage;
12. Capillary wrong size, larger diameter, throttling depressurization enough;
13. The ice wall cooling system;
14. Part of the containment cooling system;
15. The refrigeration system with air;
16. The compressor compression, reduce the displacement.
Five, the compressor can't start the troubleshooting sequence:
1. The power failure, the voltage is too low;
2. Burn out or switch damage insurance tube;
3. Start capacitor damage;
Overheating protection not reset or failure; 4.
5. A variety of relay not reset or failure;
6. The motor winding break or destroy.
Six, heat exchanger are key components of dehumidifier
Single-row type heat exchanger dehumidifier were made with aluminum, aluminum tube, water can't stay on the aluminum tube, soon drip into the water tank, therefore dehumidifier just boot cause illusion "good quick, desiccant, but machine stops working a drop of water will soon stop.
Wings arranged partial type heat exchanger dehumidifier using aluminium, copper pipe connection is made, aluminum contact area is big, water will be full of aluminum after will begin to drop, so just boot cause "poor water slowly. Dehumidification" illusion, but after downtime, drip can persist for a period of time.
