Judgment and Treatment of Simple Faults of Dehumidifier

　　Check the ventilation system of Dehumidifier

　　The components are the inlet and outlet air grilles, air filter screens and evaporators, as well as fan motors and blades. The damage to the air grilles is generally an aging phenomenon, and the inlet or outlet air is severely obstructed, affecting ventilation. Checking the air filter screen is even simpler, just check for any damage or blockage by dust. If there is dust, clean it in a timely manner.

　　Check evaporator

　　Mainly check for surface icing and dust accumulation. The detection method for fans and blades is similar to the most commonly used fans in our family, so there is no need to elaborate. It is worth noting that the loosening of screws cannot be ignored. Sometimes, the fan blades of small Dehumidifier are severely blocked by dust accumulation.

　　Check for faults in the electrical system

　　It mainly includes three states: the compressor and fan are not working; The compressor is not working and the fan is normal; Both the compressor and fan are running, but the refrigeration is malfunctioning. If such problems occur in the body, first check if the power supply is cut off and if there are any problems with the switch. If there are no problems with the power supply and switch, only seek help from the seller, who will send professional personnel to provide after-sales service for you.

　　Refrigeration system malfunction and compressor malfunction

　　Failure of the refrigeration system and compressor can also lead to no longer dehumidifying. For example, professional faults such as complete refrigerant leakage, blocked refrigeration system, and compressor displacement are beyond the reach of our general customers.

　　What if the noise of the Dehumidifier becomes louder?

　　There are multiple reasons for loud noise

　　The uneven ground causes the Dehumidifier to be placed unevenly, the parts are loose or there are foreign matters in the body, and the fan blades are damaged or deformed, causing dynamic balance damage; Starter failure, collision between pipelines (copper pipes), fan oil shortage; Excessive wear on fan bearings, excessive noise from compressors, excessive refrigerant or lubricating oil filling, resulting in corresponding liquid hammer. The specific problem needs to be verified before it can be determined. Replace the accessories, place the Dehumidifier stably, fasten the parts on the Dehumidifier, and remove the foreign matters in the Dehumidifier. Replace damaged or deformed fan blades with new ones, lubricate the fan bearings, and reduce noise.
