407 air conditioner fan stops by itself and then giant again

Hello friends, I have a problem with 407 digital air conditioner, when I turn on the car air conditioner, the internal fan motor stops spontaneously while working, but it does not appear on the screen, it does not blow, then it spontaneously activates sometimes it does not cause problems for days, sometimes it does not activate when I turn it on.

Since my teacher is a digital air conditioner, can there be a problem in the sensor that measures the temperature inside. It may be cutting electricity because it measures incorrectly. I do not have full information, but this came to my mind

There is a thermal diode in the resistance, it will be broken, but if it is broken, it will not blow 1-2-3 at all when it is taken to 4 it would be blasting.

Solution,;
Since the friends could have the same problem, the solution was very simple. Services could not find if the car was left in the heat, the air conditioner stopped blowing the fan.
