I have an 18 split air conditioner, which is clean, and it was working fine. When I moved it, it worked for 3 days but someone connected it incorrectly, and the control board burned out. It needs a new board, and I couldn't find one with its compressor. I'm selling it because I bought a new one. If anyone has an idea where I can find the control board, I would like to buy it and install it.
