Good morning I went to see a split of 6000 refrigerators, the lady told me that she was not walking. He arrives and tells me that he was a technician a week ago to clean the equipment and then told him that the engine was burned. Then I went and did not turn on anything in the indoor unit, but nothing, not even the light or the classic beep when plugged in. Current reaches the plate. I look at the outdoor unit I test the direct motor and it starts, engine is not the problem. What if when the split is plugged in, the contact clicks and sticks and only turns on the outside fan, does not start anything inside or the engine. Change the contact for a new one thinking that it was the problem and it remains the same, do you think it is a plaque problem or what could it be?

Hello how are you doing? If it were a problem with the board, the engine of the outdoor unit did not start you and you wrote that it does, check how the compressor is connected in the control system and check the electrical voltage when it reaches the outdoor unit.
