Dehumidifier starts soon after the stop, after a long time to start again, dehumidification effect is very poor

　　Check the faults: (1) The wind speed of the tuyere is lower than the normal value; (2) The resistance value between the leading lines of the fan motor was measured with a multimeter, which was found to be much lower than the normal value.

　　Maintenance method: According to the detection situation, it is judged that the inter-turn short circuit of the winding coil of the fan motor, resulting in the reduction of the fan speed and air volume, resulting in this fault. Put on a new fan motor, troubleshooting.

　　Cause analysis: dehumidifier compressor for rotary compressor, heat resistant performance is poor, the fan motor speed is reduced, to reduce that flows through the condenser air volume reduction, causes the compressor exhaust pressure, cause the compressor overheating protection (stop), the compressor overheating to cooling temperature can be reduced to normal after a long time, so the length of time after cooling compressor can start again.
