Would anyone have the LED failure codes for A Trane XE1000 heatpump.Mine blinks 3quick-short break-3quick. I think that it may have something to do with the defrost cycle. When this occurs the compressor will not come on but the contactor closes and there is voltage through the start capacitor. I can kill the low voltage, wait a while and the LED will resume blinking 1 per second and the pump will energize. Maybe a control board problem or valve ????
