Air Conditioner Not Receiving Signals from Remote Control or Remote Control Malfunctioning
Cause:
- Unstable voltage, static electricity interference.
- The control is not within the receiving range of the air conditioner signal.
- The control is not aimed at the correct window of the air conditioner.
- The sensitivity of the remote control is not high, the display screen is blurry.
- The remote control does not display when operated.
- Fluorescent lights are installed in the room.
Solution:
- Unplug and plug back in after approximately 3 minutes, then turn the indoor unit back on once more.
- Keep in mind that the maximum signal reception range of the air conditioner is 8 meters.
- Select the angle and direction of the remote control directly toward the receiving window on the indoor unit.
- Check and replace the battery if the battery power is too low.
- Check for damage on the remote control and repair or replace another remote control if necessary.
- Turn off fluorescent lights and bring the remote control close to the indoor unit, then try again.
No air coming out of the indoor unit
Cause:
- The air path of the indoor unit is obstructed and blocked.
- The indoor unit is in heating mode or heating mode has just been turned on.
Solution:
- Remove obstruction from the indoor unit.
- The indoor unit not blowing air out when heating mode is just turned on is normal as it will prevent the indoor unit from blowing cold air out. After a few minutes, the indoor unit will blow air normally again.
Air conditioner not functioning
Cause:
- No power input due to power outage, loose plug.
- Circuit breaker tripped, fuse blown, or electrical wires damaged.
- Functions set on the remote control are incorrect.
Solution:
- Wait until power returns, check and reconnect if plug is loose.
- Request a professional to come and replace.
- Adjust functions on the remote control correctly according to the user manual.
Mist emitted from the indoor unit air duct
Excessive indoor temperature or humidity may lead to rapid cooling of indoor air, resulting in the phenomenon of fog. You can continue using it confidently because, after a period of time, if the temperature and humidity decrease, the fog will disappear.
AC not functioning based on the set temperature
Cause:
- Thermostat is running in automatic mode.
- The selected temperature exceeds the allowable limit for AC operation.
Solution:
- Turn off the automatic mode, and you can then adjust the AC to run according to your desired temperature.
- Note: The temperature range of the AC will typically be between 16 and 30 degrees Celsius.
Inefficient Cooling/Heating Effect of the Air Conditioner
Cause:
- Voltage is too low.
- The air conditioner filter is heavily laden with dust.
- The temperature setting is out of the allowed range.
- Main door and windows are left open.
Solution:
- Only operate the air conditioner when the voltage supply is normal.
- Clean the filter regularly and establish a cleaning schedule.
- Adjust the temperature within the allowed range for the air conditioner (16-30 degrees Celsius).
- Check and close the main door and windows properly if left open.
Unpleasant Odor Emitted by the Air Conditioner
Using the air conditioner for a prolonged period without cleaning the evaporator coil and filter properly can create an environment for mold and bacteria, resulting in an unpleasant odor. It is essential to have a regular cleaning schedule for the air conditioner (maximum of once every 6 months) to eliminate the unpleasant odor emanating from the air conditioner.
Air Conditioner Operating Abnormally
Possible causes include: obstacles, lightning strikes, etc. To ensure safety in such cases, you should disconnect the power and change the power source, then turn the unit back on.
Mist Emitting from the Evaporator Coil
This is a natural phenomenon when transitioning from the cooling mode to the heating mode of the air conditioner. The sudden encounter of cold air with warmth creates mist, which is normal, and you can be assured if this happens.
Hearing Noise When Turning the Air Conditioner On or Off
Hearing the sound of flowing water when turning the air conditioner on or off is a common phenomenon caused by the refrigerant flowing inside the evaporator and condenser coils. No need to worry if this happens.
Hearing cracking or snapping noises is due to friction between the panel or other components as they contract or expand due to temperature changes. This is also a completely natural occurrence.
