Sensor trouble
No
Are the
connectors of the sensor
"A" connected correctly to the
outdoor unit control
PCB ?
Yes
Start of defect diagnosis
Connectors
Type 256, 366
"A" = CN020(C2)
"A" = CN021(C1)
"A" = CN022(TO)
"A" = CN023(TD, TS)
Type 486
"A" = CN020(C2)
"A" = CN021(C1)
"A" = CN022(TS)
"A" = CN023(TO)
"A" = CN024(TD)
Correct the connections.
Are the characteristics
of resistance values of the
sensors C2, C1, TS, TO and
TD sensors normal? *
Replace the sensors C2, C1, TS, TO
and TD.
No
Yes
Check the outdoor unit control PCB.
Replace if PCB has failed.
* Refer to “5-5. Table of Thermistor Characteristics.”
