So we are talking about command plate problems if the equipment is recommended to take it to the same but the excuse they make is that the installer has to be registered now if if you are going to have to remove the evaporator plate You can do it without disconnecting the unit but you will have to disassemble the housing of the unit so that you carefully remove the plate and take it to repair for it you have to carry platelets with remote control and sensors in my province of Tucumana they do it to that work and I it cost $ 600
