Troubleshooting
Phase Sequencer
The unit with Scroll Compressor only can rotate in one direction. For this reason, a protective device (phase
sequencer) is
fi
tted to prevent incorrect wiring of the electrical phases. When the three phases are not
connected correctly, the phase sequencer operates, and the unit will not start.
This device is located in the control box of the outdoor unit.
The following table shows the LED indicator light for phase sequencer under normal operation and fault
conditions.
