2.2.2.17. “L5-00” – Output overcurrent detection
Faulty compressor.
Check compressor (see
"Compressor" on
page 49
).
Check connections and wiring of the com-
pressor.
Check expansion valve (liquid back issue)
(see
"Electronic expansion valve" on
page 50
).
Check the refrigerant charge. Refer to the
nameplate for correct charge.
Replace compressor when required (see
"Replacing compressor" on page 76
).
Investigate reason of breakdown.
Replace expansion valve when required
(see
"Replacing expansion valve body" on
page 81
).
Fix possible leak.
Faulty or disturbance of the power supply
(imbalance > 10%). Power drop. Short cir-
cuit.
Check if the power supply is conform with
regulations. No fluctuations in frequency.
Adjust power supply when required.
Power reset via outdoor unit.
Faulty outdoor fan motor.
Check the fan motor (see
"Fan motor" on
page 52
).
Check fan motor connections and wiring.
Replace fan motor when required (see
"Replacing DC fan motor assembly" on
page 79
).
Adjust wiring when required.
Faulty capacity adapter on outdoor PCB.
Check if the correct adapter is installed.
Check if the correct spare part is installed.
Adjust capacity adapter when required.
External factory (e.g. electrical noise).
(cause when error is reset after power
reset, and error happens again after a
while).
Check for source which could cause elec-
trical interference.
Avoid electrical interference.
Trigger
Effect
Reset
Outdoor inverter PCB detects overcurrent
to power transistor.
Unit will stop operating.
Manual reset via user interface.
Possible cause
Check
Corrective action
Refrigerant circuit is clogged.
Check for possible blockage.
Replace blocked part when required.
Humidity in refrigerant (ice formation in
expansion valve).
Check for humidity in the refrigerant.
In case of suspicion of humidity, recover,
vacuum and recharge with virgin refriger-
ant.
Non condensables in refrigerant.
Check for non condensables in refriger-
ant.
In case of suspicion of non condensables,
recover, vacuum and recharge with virgin
refrigerant.
Faulty outdoor inverter PCB.
Check outdoor inverter PCB.
Check if the alive led is blinking in regular
intervals.
Check if the correct spare part is installed.
Adjust the power to the outdoor inverter
PCB.
Replace outdoor inverter PCB (see
"Replacing main PCB" on page 89
).
Faulty compressor.
Check compressor (see
"Compressor" on
page 49
).
Check connections and wiring of the com-
pressor.
Check expansion valve (liquid back issue)
(see
"Electronic expansion valve" on
page 50
).
Check the refrigerant charge. Refer to the
nameplate for correct charge.
Replace compressor when required (see
"Replacing compressor" on page 76
).
Replace expansion valve when required
(see
