3.36 Compressor Damage Alarm
Error Code
E6
Applicable
Models
All outdoor unit models
Method of Error
Detection
Determine the symptom to be error by detecting the revolutions of the compressor and pressure
values detected by the high and low pressure sensors, and further making a comparison between a
theoretical current value of the compressor calculated from parameters detected and an actual
current value detected by the power transistor.
Error Decision
Conditions
When a state in which the actual current value of the compressor is abnormally high (by 130% or
more) compared to the theoretical current value continues for a period of 30 minutes.
∗
In case of a system with multi outdoor units, the system will return an alarm if there is any
operational unit other than that applicable to
E6
or determine to be error if not.
Supposed
Causes
Defective compressor
Defective high pressure sensor
Defective low pressure sensor
Defective outdoor unit main PCB
Defective inverter PCB
Troubleshooting
NO
YES
Are the
characteristics
of the high pressure
sensor normal?
(
∗
1)
(1) Mount a pressure gauge on the high and low pressure
service ports.
(2) Reset the power supply, and then restart the operation.
Replace the high pressure sensor
(S1NPH).
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
NO
YES
Are the
characteristics
of the low pressure
sensor normal?
(
∗
1)
Replace the low pressure sensor
(S1NPL).
Connect the service checker to compare the high
pressure and low pressure checked by the service
checker and the actual measured values of the high and
low pressure sensors. (
