Are you asking why there is no response when you press the touch button of the incubator? Circuit failure, poor contact, etc.

There is a circuit fault in the incubator, which causes the buttons to be unresponsive. You can check whether the power supply of the incubator is normal, such as whether the plug is firmly inserted into the socket and whether the power cord is damaged.

Poor contact with the touch key leads to no response when pressing the key. Check the touch button for dirt or water stains, and if so, wipe it clean with a soft cloth.
