(a)Check Indicator Table

Whether a failure exists or not on the indoor unit and outdoor unit can be know by the contents of remote controller eroor code, indoor/outdoor unit green LED (power pilot lamp and microcomputer normality pilot lamp) or red LED (check pilot lamp).

Cause

Normal

Power OFF, L phase wiring is open, power source failure

Indoor unit microcomputer failure

Remote controller wires X and Y are reversely connected. *For wire breaking at power ON, the LED is OFF. Remote controller wire is open. (X wire breaking : A beep is produced and no indication is made. Z wire breaking : No beep and no indication) The remote controller wires Y and Z are reversely connected.

Poor connection or disconnection in wires connecting the indoor and outdoor units.

When multiple remote controllers are used for control, the power supply to some indoor units is OFF.

Indoor unit PCB fault

The remote controller wire Y is open. The remote controller wires X and Y are reversely connected. Noise is penetrating the remote control lines. The remote controller or indoor control PCB is faulty. (The communications circuit is faulty.)

Indoor / outdoor transmission error.

Outdoor unit control PCB is faulty when the power is turned on, or the inverter parts are faulty (FDCVA 151~251 type).

Outdoor unit microcomputer failure

Indoor unit heat exchanger thermistor failure

Indoor unit return air thermistor failure

Heating overload (indoor heat exchanger temperature is abnormally high) and indoor heat exchanger thermistor is faulty.

The float SW operates (with FS only). Drain up kit wiring fault.

When multi-unit control by remote controller is performed, the number of units is over (more than 17 units). Two remote controller are provided for one controller is performed.

Fan motor is faulty (FDTA 501, 601 type, FDKN type).

Remote controller thermistor failure

Diagnosing of microcomputer circuit

Note (1) The green LED in the outdoor unit is used in the FDCA301 ~ 601 models only.
