I have the same problem happened with me, I found that the compressor sensor is faulty, now 2 solutions either to change the compressor as sensor cannot be repaired which will cost more money, or bypass the compressor sensor by small copper wire and it will work perfect, I chose to bypass the compressor sensor and it worked fine with me so far
