The airconditioner may not operate properly if the voltage is out of this range. 2) Is the link cable linking the indoor unit and the outdoor unit linked properly? The indoor unit and the outdoor unit shall be linked by 5 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the airconditioner may not operate properly. ) When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the airconditioner. Operation of air conditioner Explanation The STD operation indication LED blinks when a power plug of the indoor unit is plugged in for the first time. 2 In a COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the INDOOR FAN should operate. In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate. Fan speed setting is not allowed in AUTO or DRY mode. 4 Compressor stops operation intermittently in DRY mode. 5 Compressor of the outdoor unit is operating although it is turned off in a HEAT mode. 6 Timer LED only of the indoor unit lights up and the air conditioner does not operate. 7 The compressor and indoor fan stop intermittently in HEAT mode. 8 Indoor fan and outdoor fan stop operation intermittently in a HEAT mode. 9 The compressor stops intermittently in a COOL mode or DRY mode, and fan speed of the indoor unit decreases. It indicates power is on. The LED stops blinking if the operation ON/OFF button on the remote control unit is pushed. In happens after a delay of minutes when the compressor is reoperated. The same phenomenon occurs when a power is on. As a phenomenon that the compressor is reoperated after a delay of minutes, the indoor fan is adjusted automatically with reference to a temperature of the air blew The speed of the indoor fan is set to LL in DRY mode. Fan speed is 5 steps is selected automatically in AUTO mode. Compressor operation is controlled automatically in DRY mode depending on the room temperature and humidity. When the unit is turned off while deice is activated, the compressor continues operation for up to 9 minutes (maximum) until the deice is completed. Timer is being activated and the unit is in ready mode. The unit operates normally if the timer operation is cancelled. The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protect the compressor from overheated air in a HEAT mode. The compressor operates in a reverse cycle to remove exterior ice in a HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heater operation The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature. 4) Indoor unit observes operation condition of the air conditioner, and displays self diagnosis details on the display panel.

34 5 PCB Inspection 5 Cautions for Part Replacement. The human body carries much static electricity. Before touching a part for repair, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go through the metallic portion to the earth. Especially when handling any micro computer or IC, carefully remove such static electricity before touching them. 2. When repairing any part on a work bench, be sure to place an insulative sheet on the bench and always keep the sheet surface neat without any metal fragments. If any such fragment touches a part, a secondary trouble will possibly be caused in the part.. Before replacing any parts, be sure to turn off the power supply. If such replacement is done with the power supply kept on, an electric shock, short circuit or destruction of a part may result. 4. During replacement or repair of a part, carefully handle it : The printed circuit board has fine lead wires (jumper wires) and glassmade parts (diode) on its substrate. So if a circuit board is roughly handled, such lead wires and parts will be easily broken or damaged by bending or shock. 5. When soldering the lead wires of any new part, be sure to polish them using an emery paper or the like before solding them. Since the lead wires of any new part are covered with an oxide film, solder cannot adhere to the lead wires if not polished. 6. When soldering any part, care should be exercised not to apply any highwattage soldering iron to the part for a long time. Some parts are of so low a heat resistance that they may be broken or have the properties changed if a soldering iron is so applied (Otherwise, the pattern may possibly be separated and raised). 7. The heat of the soldering iron should be transfered to the entire object to be soldered. If the solder pieces are not well fused due to insufficient transfer of the heat from the soldering iron, no satisfactory electrical continuity can be assured even if the soldered objects appear well connected to each other. 8. The solder used should be limited to a minimum. If excessive solder is used, it will cause interpattern contact, which may cause malfunction of the circuit. 52 Procedure The parts should be replaced in the following procedure. Check for any faulty part. Detach the faulty part. Replace it with a new part. Check the operation of the new part. The repair is completed. 57
