CGAFC60 installed in 2004 has 12 condenser fans has 6 VFD’s controlled by Stand alone Tracer MP No display. We just started servicing this building. 6 fans are running half speed and 6 fans not called to run. Both liquid lines are hot. I don’t have any other Tracer buildings. Suggestions Short of calling Trane service. I’m going back to check my thermistor connections today.
