Dehumidifiers that are used for a long time are prone to problems. Hong Kong Junhong Electrical Repair will teach you two tricks!

Dehumidifiers are one of the most common equipment, especially in humid weather, or in shopping malls in the south, stores, etc., will prepare them to provide customers with a better shopping experience. However, long-term use of the dehumidifier will shorten its service life, so malfunctions are inevitable. Now let’s briefly talk about the problem of dehumidifier failure, and we can use the methods of repairing dehumidifiers by the masters of Hong Kong Junhong Electrical Maintenance to provide more people with reference.

1. Poor dehumidification effect

There are often multiple reasons for poor dehumidification effects. But there are two common reasons.

1. The evaporator is faulty. It may be because there will be some oil stains on the pipe interface, which may be caused by leakage. Therefore, if the refrigerant is released directly, the leakage area will be welded directly. And re-evacuate and inject refrigerant again, so the problem can be easily solved.

2. The compressor has poor heat resistance. General brand machines tend to invest relatively high costs in compressors. So there are fewer problems. Generally, the compressor of a dehumidifier is a rotary compressor with poor heat resistance. Once the fan motor speed decreases, it will easily cause the pressure to rise, and the compressor will shut down for protection if it overheats. This will lead to temporary shutdown and temporary poor dehumidification effect.

3. Ice blockage problem. In addition, it is also possible that the system contains a lot of water, which directly causes the refrigerant to cool down, causing the water to freeze and block the pipes, preventing the refrigerant from flowing. As a result, the effect becomes worse or even unusable. Hong Kong Junhong will solve the problem by adding an ice machine, shutting it down to vacuum, and then starting it up again.

2. The dehumidifier cannot be started after being deactivated.

If it is found that the power supply voltage is relatively normal, after starting, you hear a buzzing current sound, but there is no way to start. Then there may be a problem with the compressor. Just tap the compressor several times. If it works normally after tapping hard, then there is no problem. But if it doesn't work properly after knocking, you need to disassemble the equipment to see if the compressor is faulty. Needs repair or replacement.

The above is based on the maintenance experience provided by Hong Kong Junhong Electrical Maintenance Company for the maintenance plan of Huamei dehumidifier. Of course, for customers, once a dehumidifier is found to be faulty, it must be repaired as soon as possible, because dehumidifiers are often relatively small equipment, so to repair the dehumidifier, you need to bring it to Kwun Tong for repair.
