Then it sounds like it was the transistor, same as mine.The problem solved. The AC shop cannot find it they suggested to an electrical shop. Something which is not related to recharging the refrigerant at all, it was purely electrical inside the AC amplifier. They removed the AC amplifier box out and opened the box and then replaced something which is I don't know. Thanks for help anyway!!
Easy to comment when you can see the actual board,other wisw Yes it would be an educated guess, but there are some with the offending Mosfet, they get rid of the electromagnetic relay that this one may trigger..No power mosfets on that board, in fact, no power transistors, just good old fashioned switching transistors, which is really all you need to control a couple of relays.
Now - it appears that some folks have enough of a need to post comments that they are willing to guess incorrectly, I'm noticing this more & more recently, and it is becoming worrisome.
