No. Symptom LED indication Abnormal point/ Condition Condition Remedy 19 Outdoor unit operates. 8-time fl ash 2.5 seconds OFF Zero cross detecting circuit Zero cross signal cannot be detected. It occurs with following cases. 1 Instantaneous power voltage drop.
28 1 1-5. TROUBLESHOOTING FLOW Are the voltages balanced? Disconnect the connector between compressor and the IGBT module (IC700). Replace the inverter P .C. board. Check the voltage between terminals. Check the compressor . See 1 1-5. “Check of compressor”.
29 F Check of compressor start failure D Check of compressor winding E Check of compressor operation time ● Disconnect the connector between the compressor and the IGBT module (IC700), and measure the resistance between the compressor terminals.
30 G Check of outdoor thermistors H Check of R.V . coil Replace the thermistor except RT64. When RT64 is abnormal, replace the inverter P .C. board. Replace the inverter P .C. board. No No Is the resistance of thermistor normal? (Refer to 1 1-6.1.) Reconnect the connector of thermistor .
31 I Check of outdoor fan motor Is the resistance between each ter- minal of outdoor fan motor normal? (Refer to 1 1-4.) Disconnect CN932 from the inverter P .C. board, and turn on the power supply . Rotate the outdoor fan motor manually and measure the voltage of CN931.
32 J Check of power supply Is there voltage 230 V AC between the indoor terminal block S1 and S2? No Ye s Replace the indoor electronic control P .C. board. Rectify indoor/outdoor connecting wire. Ye s If light up, OK. If fl ash, refer to 1 1-3. Does the upper lamp of OPERA TION INDICA TOR on the indoor unit light up? Does LED on the inverter P .
33 Press OPERA TE/ST OP (ON/OFF) button of the remote controller (the set temperature is displayed) with the remote controller headed towards the indoor unit. 1 Expansion valve operates in full-opening direction. OK NOTE : After check of LEV , do the undermentioned operations.
34 Check the outdoor fan motor . (Refer to 1 1-5. .) Is the fuse (F901) blown on the in- verter P .C. board? Check the connection of the connectors (CN931, CN932) of the outdoor fan motor . If the connection is poor , make it correct. Operate the outdoor unit by starting EMERGENCY OPERA TION.
35 M How to check miswiring and serial signal error T urn the power supply OFF . Is there rated voltage in the power supply? Ye s No Check for incorrect indoor-outdoor connecting wiring.
36 N Electromagnetic noise enters into TV sets or radios Ye s Is the unit earthed? No Earth the unit. Ye s Is the distance between the antennas and the indoor unit within 3 m, or is the distance betwe.
