E7-00" - Fan Motor Abnormality - Daikin SA R32 Sky-Air RZAG-L Service Manual

ESIE16-03B | Part 2. Troubleshooting
Possible cause
Faulty expansion valve.
Faulty 4-way valve.
Faulty outdoor unit main PCB.
Faulty power module = faulty outdoor
inverter PCB.
Refrigerant shortage.
Humidity in refrigerant (ice formation in
expansion valve).
Non condensables in refrigerant.
Stop valve is closed.
2.2.2.5. "E7-00" – Fan motor abnormality
Trigger
Fan does not start in about 15~30 sec-
onds = fan motor lock.
It can occur that E7-00 error is triggered
even when the fan motor is running
caused by a NG hall signal.
Possible cause
Faulty outdoor fan motor.
Faulty outdoor inverter PCB.
Blown fuse.

Check
Check the expansion valve (see
tronic expansion valve" on page
Check the 4-way valve (see "4-way valve"
on page 47).
Check if the HAP LED is blinking in regu-
lar intervals (see "Main PCB" on page
Check if the correct spare part is installed.
Check if the outdoor main PCB receives
power.
Check outdoor inverter PCB.
Check if the HAP LED is blinking in regu-
lar intervals (see "Main PCB" on page
Check if the correct spare part is installed.
Check for refrigerant shortage. Refer to
the nameplate for the correct charge.
Check for humidity in the refrigerant.
Check for non condensables in refriger-
ant.
Check stop valve.
Effect
Unit will not stop operating.
Unit will stop operating.
Check
Check the fan motor (see "Fan motor" on
page 52).
Check fan motor connections and wiring.
Check outdoor inverter PCB.
Check if the HAP LED is blinking in regu-
lar intervals (see "Main PCB" on page
Check if the correct spare part is installed.
Check the fuse on the outdoor unit PCB's.
2.2. Error based troubleshooting
Corrective action
"Elec- Replace the expansion valve body (see
50). "Replacing expansion valve body" on
page 81) or motor (see
sion valve motor" on page
required.
Replace the 4-way valve coil (see
"Replacing 4-way valve coil" on page
or body (see "Replacing 4-way valve
body" on page 73) when required.
Restore the power to the outdoor main

Replace outdoor main PCB when HAP
LED is not blinking in regular intervals
(see "Replacing main PCB" on page
Restore the power to the outdoor inverter
PCB.
55). Replace the outdoor inverter PCB when
required (see "Replacing main PCB" on
page 89).
Charge the correct refrigerant amount
when required.
In case of suspicion of humidity, recover,
vacuum and recharge with virgin refriger-
ant.
In case of suspicion of non condensables,
recover, vacuum and recharge with virgin
refrigerant.
Open stop valve when required.
Reset
Automatic reset after a continuous run.
Refer to ""E7-00" – Fan motor abnormal-
ity" on page 30.
Manual reset via user interface.
Corrective action
Replace fan motor when required (see
"Replacing DC fan motor assembly" on
page 79).
Adjust wiring when required.
Restore the power to the outdoor inverter
PCB.
