Last Updated on April 2, 2022 by Shawn Lee


Fault phenomenon
Reason Solution
1、Heater fan not working
Set temperature below room temperature (LCD switch)Increase the set temperature
2、The cooling fan not working
Set temperature higher than room temperatureTurn down the set temperature
3、The cooling and heating effect is not ideal (cool air for heating, hot air for cooling)
There is gas trapped inside the machine or the pipe inlet filter is blockedUnscrew the vent valve to exhaust
4、Insufficient air volume
Floor-standing water air conditioner the air intake net is dirtyClean the pipe filter
5、Wind speed selection failure
A damaged inner coil of the motorClean the air inlet net
6、Water leaking outside the machineThe machine interface is not level, causing water leakage or water leakage inside the machine (the probability of this type of failure is very small)Replace with new motor
7、LCD remote control not respondingBad contact or dead batteryAdjust the horizontal position of the machine and reinstall it
8、Fan not workingDamaged switch or motorReplace with the new cooler
9、Loud noiseForeign objects enter the wind rotor or the air inlet net is blockedReplace with the new battery

These 9 common fan coil unit usage problems can be solved by yourself without spending money to find a maintenance worker.
Ultra-thin Floor Vertical Fan Coil imported from China, on the premise that the quality is guaranteed, can be solved by using the 9 methods I provide for you.
As a foreign dealer, you need to understand the product structure and parameters of imported fan coil products. In addition to the recommended installation method for end-users, you also need to understand the daily use and maintenance.
China’s fan coil unit manufacturer – Baoding Yuexin provides you with the following professional information.
If you need more, you can contact the manufacturer for help.

Let me list 9 common anomalies for you:

  1. When your customer uses the fan coil unit, turn on the power supply, turn on the fan coil unit heating function, and the fan coil unit does not work;
  2. When your customer uses the fan coil unit, turn on the power supply, the fan coil unit starts the cooling function, and the fan does not work;
  3. After your customer uses the ultra-thin fan-coil to connect to the power supply, the fan coil unit works for cooling, the heating effect is not ideal, or the heating blows cool air, and the cooling blows hot air;
  4. Another common phenomenon is that the 4-pipe Floor Standing Fan Coil Unit can be started normally, but the cooling/heating air volume of the fan coil unit is significantly reduced;
  5. The fan coil airspeed selection fails, the air volume adjustment fails, and the wind speed and air volume are not controlled;
  6. The fan coil is leaking. This is very rare in our company’s fan coil units. After the fan coil unit has been used for a period of time, water leaks from the outside of the machine. If a large number of water leaks continuously, you can only consult the manufacturer you purchased for help;
  7. The ultra-thin fan coil unit can remotely control the wind speed and air volume of the LCD display, but the LCD remote control has no response in actual use;
  8. Turn on the power, but the silent-fan-coil-unit does not respond and does not work;
  9. After the floor-standing water air conditioner is used for a period of time, the noise increases during operation;

You need to know, what are the reasons for the above 9 phenomena?

  1. When the fan coil unit is in use, the set temperature is lower than the room temperature (liquid crystal switch);
  2. Use the fan coil to set the temperature higher than the indoor temperature;
  3. There is gas remaining inside the ultra-thin fan coil unit;
  4. The water inlet filter of the wall-mounted fan coil unit is blocked or the air inlet net is dirty;
  5. The internal coil of the fan coil motor is damaged;
  6. The machine interface of the exposed fan coil units is not level, resulting in water leakage or water leakage inside the machine (the probability of this type of failure is very small);
  7. The fan coil unit is in poor contact or the battery is dead;
  8. The floor-standing water air conditioner switch or motor is damaged;
  9. Foreign matter enters the wind wheel of the fan coil unit or the air inlet network is blocked.

The above 9 kinds of fan coil use problems and solutions.

  1. Increase the set temperature of the floor-standing water air conditioner;
  2. Lower the set temperature of the silent fan coil unit;
  3. Unscrew the floor-standing water air conditioner vent valve to exhaust or clean the pipe filter;
  4. Clean the air inlet network of the fan coil;
  5. Replace the new motor of the fan coil unit;
  6. Adjust the horizontal position of the machine to reinstall or replace the new surface cooler;
  7. Replace the new battery of the real Chinese fan coil manufacturer;
  8. Replace the new switch or motor of the fan coil unit;
  9. Check whether there are foreign objects in the wind wheel of the floor-standing water air conditioner, and clean the air inlet net.
