OEM Portable Dehumidifier

Parameters

Common dehumidifier failures and solutions

1. the OEM Portable Dehumidifier effect is not obvious, the compressor automatically stops after working for a period of time

Check the fault: 

(1) Check the evaporator, the surface condensate is even, and prove that there is no blockage; 

(2) Check the condenser and find that there is a large temperature difference between the tubes, which proves that the condenser is not blocked; 

(3) The compressor works for a period of time. After the time, the machine will stop automatically, and the fan operation and control system will be normal; 

(4) Check the overheat protection of the compressor, and there is no action; 

(5) It is estimated that the compressor is faulty, and the compressor protects the action, causing the compressor to stop automatically. . It was found that the winding resistance when the compressor was just stopped was different from the resistance when the compressor was cold.

Maintenance method: Replace with a new compressor, the dehumidification function returns to normal. The original compressor has unstable winding resistance, and the winding temperature rises rapidly when the power is turned on, so that the protector in the compressor operates, so that the compressor automatically stops automatically and cannot perform normal dehumidification. As the internal resistance increases, the power consumption also increases.
