Trane XL19i straight cooling condenser model # 2TT9060B1000AA, late model 01/2006 twin compressor set up. I dont work on alot of these units and i cant get the outdoor to fire up. Im getting 24 vac to the Blue(common) & Red (voltage) to the control board in the outdoor unit, as well as 24 vac to the blue (common) & yellow/red (Y1)but im not getting any 24vac out. There are 2 lights blinking, Status (one blink /sec) & Y2 (one blink /sec). Im assuming the status light is similar to the "heartbeat" of the unit and is suppost to blink once per second under normal operating conditions and the Y2 means there is a problem with the second stage compressor since it is blinking. The output of the board plugs into a loom that feeds 24vacs to the contactor coils and the low voltage to the fan motor. Also, the larger of the 2 compressors (Y1 ?) feels hot. Like i said before, i work mainly with York and dont do alot of Trane work...especially on a almost brand new unit.

Any help would be appreciated
