Troubleshooting by LED on Inverter Outdoor Unit PCB
The following diagnosis can be conducted by turning on the power switch and checking the LED
indication on the printed circuit board of the outdoor unit.
4
: LED on
3
: LED off
5
: LED blinks — : Not used for diagnosis
Notes:
1. Turn off the power switch, and turn it on again after 5 seconds or more. Check the error
condition, and diagnose the problem.
2. Turn off the power switch. After 5 seconds or more, disconnect the connection wire (2). Then
turn on the power switch. If the HAP on the outdoor unit PCB flashes after about 10 seconds,
the indoor unit PCB is faulty.
3. The error detection monitor continues to indication the previously generated error until the
power switch is turned off.
Be sure to turn off the power switch after inspection.
4. Also check for open phase.
