Faulty expansion valve.
Check the expansion valve (see
"Elec-

).
Replace the expansion valve body (see
"Replacing expansion valve body" on
page 81
) or motor (see
"Replacing expan-
sion valve motor" on page 82
) when
required.
Faulty 4-way valve.
Check the 4-way valve (see
"4-way valve"
on page 47
).
Replace the 4-way valve coil (see
"Replacing 4-way valve coil" on page 75
)
or body (see
"Replacing 4-way valve
body" on page 73
) when required.
Faulty outdoor unit main PCB.
Check if the HAP LED is blinking in regu-
lar intervals (see
"Main PCB" on page 55
).
Check if the correct spare part is installed.
Check if the outdoor main PCB receives
power.
Restore the power to the outdoor main
PCB.
Replace outdoor main PCB when HAP
LED is not blinking in regular intervals
(see
"Replacing main PCB" on page 89
).
Faulty power module = faulty outdoor
inverter PCB.
Check outdoor inverter PCB.
Check if the HAP LED is blinking in regu-
lar intervals (see
"Main PCB" on page 55
).
Check if the correct spare part is installed.
Restore the power to the outdoor inverter
PCB.
Replace the outdoor inverter PCB when
required (see
"Replacing main PCB" on
page 89
).
Refrigerant shortage.
Check for refrigerant shortage. Refer to
the nameplate for the correct charge.
Charge the correct refrigerant amount
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.
Stop valve is closed.

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 outdoor inverter PCB.
Check outdoor inverter PCB.
Check if the HAP LED is blinking in regu-
lar intervals (see
"Main PCB" on page 55
).
Check if the correct spare part is installed.
Restore the power to the outdoor inverter
PCB.
Replace the outdoor inverter PCB when
required (see
"Replacing main PCB" on
page 89
