Malfunction Decision Conditions:
During operation of cooling and heating, when outdoor current above 11.8A (UX09FE8, UX12FE8), 16.5A
(UX16FE8), 10.6A (UD09FE8, UD12FE8, UD16FE8) is detected by the current transformer (CT) in the outdoor
unit PCB.
Malfunction Caused:
1 Excessive
refrigerant.
2 Faulty outdoor unit PCB (main).
Abnormality Judgment:
Continue 3 times in 20 minutes.
Get restarted and measure
the AC current from the
outdoor LIVE terminal.
Is the measured AC current
over 11.8A (UX09FE8, UX12FE8),
16.5A (UX16FE8), 10.6A (UD09FE8,
UD12FE8, UD16FE8)?
No
Replace the outdoor unit
PCB (main).
Reclaim and recharge with
correct amount of refrigerant.
Replace the outdoor unit
PCB (main).
Check refrigerant amount.
