<# -r Shanghai American General Dehumidifier After-sales Service Hotline: --Shanghai American General Dehumidifier Repair After-sales Free Service Hotline: --American General Dehumidifier Failure Phenomenon: The dehumidifier shuts down quickly after being turned on and takes a long time to restart. The dehumidification effect is very poor. Check the fault: the wind speed at the air outlet is lower than the normal value. Use a multimeter to measure the resistance value between the lead wires of the fan motor and find that it is much lower than the normal value. Maintenance method of American general dehumidifier: According to the detection situation, it is determined that the short circuit between turns of the fan motor winding coil causes the fan speed to decrease and the air volume to decrease, which causes this fault. Replace with a new blower motor troubleshooting. Dehumidifier failure cause analysis: The compressor of the dehumidifier is a rotary compressor with poor heat resistance. The fan motor speed decreases and the air volume decreases, that is, the air volume flowing through the condenser decreases, causing the compressor exhaust pressure to increase, resulting in compressor overheating protection (shutdown). If the compressor is overheated, it will take a long time for the temperature to cool down to normal, so the compressor must wait for a long time to cool down before it can be restarted. Dehumidifier failure phenomenon: The relative humidity of the normal environment where the dehumidifier operates is %~% but the water output is very small. Check the fault: The air plate of the dehumidifier allows the dehumidifier to run. Check the evaporator and find that only a few shaped tubes have condensed water. The surface of other shaped tubes is dry. Further inspection found that there are oil stains on one pipe interface. It is judged as a leak. Kawai dehumidifier maintenance method: drain the refrigerant, weld the leaking joint, vacuum and inject refrigerant to troubleshoot. Fault phenomenon: The dehumidifier was repaired once after being used for more than a year. The test machine was shut down normally for a period of time and then used again. It was found that the compressor and fan were normal but the dehumidification effect was very poor. It was rare in an environment where the relative humidity was % and the temperature was ℃. Water condenses out. Check for faults: The air filter and the surface of the evaporator and condenser are very clean. There is no leakage of oil on the surface of the pipe. Frost appears on the capillary tube near the evaporator and it will stop soon. After a period of time, the frost melts away and the compressor can run again.
