I looked up service info your build. I believe for your model year; it uses a variable displacement compressor; meaning the compressor does not cycle off...(verify this). the compressor varies its output to stop freeze up. the method to check operation is to monitor high and low side pressures when the problem occurs. if the high side is normal and the low side is low( below 35 psi) the problem is most likely a bad low pressure switch or compressor. start with the switch its cheap.

 

The same issue here. When I sought help from specialists, I was lucky enough to find decent professionals who sorted out the problem. They replaced all the necessary parts and instructed me on how to continue using the air conditioner. I think this is the right approach to working on an appliance that needs repair. I think you can also find help at https://www.marvellous.sg/aircon-chemical-wash/. It's really effective in making the air conditioner work.
