How I was able to find the branch and piping issue in my last post was using the maintenance tool but looking at the system in the refrigerant piping view as opposed to the standard view, it really helps layout the sensors and how things are working in the system, if you look at address 12,13and 14 and compare the modes verse the temp sensors entering and leaving the evaporators you can see that something isn’t right with them. I had two suction lines that were on wrong branches and one branch addressed wrong. One of the great features of maintenance tool to help diagnose and work on these systems #teachme #mitsubishi #vrf
