Why is the display on my air conditioning system not responding? Troubleshooting tips.

The air conditioning system is an indispensable appliance, especially in the hot summer months. But what should you do if the display suddenly stops responding and even the remote control no longer allows you to make any settings?
In this article, we will look at why the display of your monobloc air conditioner has stopped responding and what simple solutions there are to fix the problem.

Possible causes if the display of your air conditioning system does not respond

If the display no longer responds and the remote control no longer enables any settings, there are two possible causes: The wall-mounted air conditioner is either not connected to the power supply or the display has been locked.

When the ON/OFF symbol flashes on the display, this indicates that the key lock has been activated.

1. check the power connection:

Ensure that the air conditioner is properly connected to the power supply. Sometimes a simple power failure or a loose connection can result in the display not responding.

2. deactivate the key lock:

When the ON/OFF symbol flashes on the display, the key lock has most likely been activated.
To fix this, press the timer button on the display for 3 seconds. When the ON/OFF button no longer flashes, the button lock is deactivated and the air conditioning system can be operated normally again. Further information on this can be found in your operating manual.

What to do if these tips don't help?

In many cases, simple causes such as an interrupted power supply or an activated button lock can lead to the display of your air conditioning system no longer responding. By checking the power connection and deactivating the button lock, you can often solve the problem quickly and easily.
However, if these steps do not resolve the problem, there may be a deeper problem and it would be advisable to seek professional help.
