Dehumidifier general troubleshooting
First, the dehumidifier does not dehumidify fault repair order:

1. Ventilation system failure:

1 inlet grille and outlet grille: A. Artificial damage or aging cracks; B. Into the wind or wind seriously blocked;

2 air filter: blocked or damaged by dust;

3 evaporator: A. Evaporator condenser fin dust; B. Evaporator surface ice;

4 fan motor: A. Damaged capacitor; B. Fan motor shaft; C. Loose rotor and shaft; D. Axis bending deformation; E. Bearing damage; F. Winding burned;

5 leaves: A. Loose fixing screws; B. Fan fan blade deformation or damage; C. The wind blade has serious dust accumulation and seriously affects the amount of air flow. D. The dehumidifier fan blades also have a phenomenon that the fan blades are stuck due to serious dust accumulation.

2. Electrical system failure:

1 compressors, fans are not turning: A. Power is cut off; B. Switch not closed; C. Broken socket; D. The voltage is too low; E. Circuit breaker is broken; F. The fuse is blown.

2 compressor does not turn, the fan turns: A. Starter failure; B. Capacitor failure; C. Overload protection.

3 The compressor and fan are all running: The cooling system is faulty.

3. Refrigeration system failure:

1 full refrigerant leakage;

2 refrigeration system blockage: A. Dirty plugging; B. Oil plug; C. Welding plug

3 excessive refrigerant;

4 The compressor has no displacement (failure).

4. Compressor failure:

1 poor compression, high and low pressure chamber helium;

2 The running parts are damaged and the compressor holds the shaft.

Second, dehumidifier noise increase failure repair order:

1. The ground is uneven and the dehumidifier is not placed smoothly;

2. Parts on the dehumidifier are loose;

3. Dehumidifiers have foreign objects;

4. Fan blade damage or deformation caused by dynamic balance is destroyed;

5. Starter failure;

6. There is a collision between the pipes;

7. Fans lack oil;

8. Fan bearing failure

9. Excessive compressor noise

10. Excessive charge of refrigerant or lubricating oil causes liquid hammering.

Third, dehumidifiers to the ground flow fault repair order:


1. The dehumidifier is unbalanced and the sink is excessively inclined, causing the water to overflow;

2. The drainage hole or drain pipe of the sink is blocked;

3. Sink damage water leakage;

4. Leakage at the outlet pipe connection or aging of the outlet pipe.

Fourth, the failure of the dehumidification effect repair order:

1. The air filter has serious dust and air flow.

2. The air outlet sucks obstacles and the airflow is blocked;

3. Fan speed becomes slower;

4. Poor room sealing, a large number of outdoor wet air infiltration;

5. Room size is too large;

6. Excessive amount of loose materials in the room;

7. Evaporator fins have more dust, so that the effect of freezing and dehumidification is reduced;

8. Frost on the evaporator surface;

9. The evaporator has a lot of accumulated oil, and the cooling and dehumidification effect is reduced;

10. Insufficient refrigerant charge;

11. Refrigerant leakage;

12. The capillary size is wrong, the diameter of the tube is large, and the throttle and pressure reduction are not enough;

13. Ice blocking in the refrigeration system;

14. Part of the refrigeration system plugging;

15. There is air in the refrigeration system;

16. The compressor is poorly compressed and the displacement is reduced.

Fifth, the failure of the compressor can not start the order:

1. Power failure, voltage is too low;

2. Circuit fuse blown or switch damaged;

3. Startup capacitor is damaged;

4. Overheat protection is not reset or faulty;

5. Various relays are not reset or faulty;

6. The motor windings are open or burned.

Sixth, the heat exchanger is a critical component dehumidifier <br> <br> single heat exchanger dehumidifier aluminum tube, aluminum exposed, droplets can not remain in tubes quickly added dropwise tank, so When the dehumidifier is turned on, it easily causes the illusion of "fast water discharge and good dehumidification," but once the machine stops working, the dripping water quickly stops.

The wing-type heat exchanger dehumidifier adopts the arrangement of aluminum sheets and the copper tubes are connected to make the aluminum sheet. The contact surface of the aluminum sheet is large. The water droplets will begin to drip after being filled with aluminum flakes. Therefore, the water outlet is likely to cause slow water discharge and poor dehumidification when the water droplets are turned on. The illusion, but after the shutdown, drip will still continue for some time.

Pneumatic Brad Nailer is used for furniture manufacture.

Most of our products have got the CE certificate.

The No.1 rule when buying peneumatic tools is not to skimp on cheap tools. Well built tools are safer and easier to use, and they will last longer than cheap tools. Not only low maintenance in progress, but also improve your productivity. In the long run, quality tools will save you money.
