Anybody know what would be causing a new (6 month old) Mitsubishi dual head minisplit condenser to keep going out on high temp limit? Unit runs fine for about a day after reset, then problem reoccurs. Spent much time on phone with tech support, checked out everything they suggested, they can't pinpoint the problem. When unit runs pressures and temps are normal, cools very well, but a day later owner calls to say it quit cooling again. Each time it has gone out on high temp and condenser is very hot. Thought it might be blockage inside, reclaimed, pulled vac and recharged with fresh refrigerant, ran fine for about a day and a half, same problem reoccured. If anybody has experienced this or has any ideas what the cause may be, I would appreciate the help.
