I have a model LMU366HV outdoor unit and a LMAN125HVT, a LMAN180HVT and a LMAN095HVT indoor units. To be more accurate I have 4 sets like this. A couple weeks ago you guys helped me figure out that my incoming power to my house was the culprit in my washer and dryer not functioning correctly. At the time it was still somewhat cool at night so all my mini splits were still in heat pump mode. Once it warmed up enough to switch them over I did the yearly maintenance of cleaning the coils, changing all the filters and making sure my drain lines were all clean and open. When I turned them back on all but one came up fine and started cooling. The one having the problem is showing a CH45 code. The manual I have says this is a problem with the condenser pipe sensor. It even shows how to check it. My problem is I can't find it. The manual has pictures of everything else but not this connector. Do you guys have any resources that can help me with this? LG won't even talk to me. It's not like I am messing with the R410A. If I need the refrigerant side worked on I have a licensed HVAC guy to do that. I am hoping the problem has something to do with me cleaning the unit as opposed to the excess voltage like the washer and dryer. So far the only thing that cost me any money from the over voltage was my well pump and a toaster. I am still fighting with my utility about them paying for my well pump and don't want to add a outdoor HVAC unit to the list.
