1. What is the Issue of Air Conditioner Only Blowing Fan?
This is a situation where the air conditioner is still on and operating normally, but it only runs the fan without cooling the air, similar to when the air conditioner is in fan mode.
2. Reasons and Solutions for Air Conditioner Not Cooling but Fan Running
The air conditioner is set to fan mode
One of the common first causes leading to the issue of the air conditioner running only the fan is accidentally pressing the wrong setting, switching to the Fan mode or activating the Dry mode, which prevents the air conditioner from cooling effectively.
Solution:
The solution is straightforward. First, turn off the Fan mode if you see the Fan icon displayed on the air conditioner remote. Next, select the Cool mode with the snowflake icon by pressing Mode until the snowflake icon appears on the remote screen.
In case there are children in the house, place the remote out of the child's reach to prevent accidental button presses.
This is also one of the factors causing the air conditioner not to cool but only run the fan. Accumulated dirt on the filter will lead to blockage, affecting the cooling efficiency, making the air conditioner room feel like it's not in use.
Solution:
To ensure efficient and smoothly operating air conditioning with optimal cooling effectiveness while saving energy, it is essential to clean the air conditioner regularly, approximately every 6 to 12 months. In addition to using maintenance services from repair units, you can clean the air conditioner filter right at home.
The steps to clean the air conditioner filter are as follows:
- Completely turn off the power of the air conditioner and then remove the air conditioner cover, take out the filter screen for cleaning.
- Use a spray nozzle to clean the filter, wipe it dry with a clean cloth, and then reinstall it as usual.

Alternatively, when the air conditioner is turned on, it shuts off after a while, leading to the outdoor unit not making noise, indicating one of the reasons the air conditioner only runs the fan without cooling.
