23 5. Troubleshooting 5- Items to be checked first ) The input voltage should be 98-64VAC. The air conditioner may not operate properly if the voltage is out of this range. ) The indoor unit and the outdoor unit shall be linked by 6 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the air conditioner may not operate pro p e r l y. 3) If a problem occurs as described in the table below, it is a symptom not related to the malfunction of the air c o n d i t i o n e r. O Operation of air conditioner The operation indication LED (Green) blinks when a power plug of the indoor unit is plugged in for the first time. In a COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the compressor should operate. In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that the compressor and indoor fan should operate. 3 Fan speed setting is not allowed in AUTO or DR mode. 4 Compressor stops operation intermittently in DR 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 DR mode, and fan speed of the indoor unit decreases. Explanation It indicates power is on. The LED stops blinking if the operation O/OFF button on the remote control unit is pushed. In happens after a delay of 3 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 3 minutes, the indoor fan is adjusted automatically with reference to a temperature of the air blew The speed of the indoor is changed automatically in DR mode. Fan speed is 4 steps is selected automatically in AUTO mode. Compressor operation is controlled automatically in DR mode depending on the room temperature. When the unit is turned off while de-ice is activated, the compressor continues operation for up to 7 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 0% of the total heater operation The compressor stops intermittently or the fan speed of the indoor unit d e c reases 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.

30 Troubleshooting 5-3 PCB Inspection 5-3- Cautions for Part Replacement. The human body carries much static e l e c t r i c i t y. Before touching a part for re p a i r, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go thro u g h the matallic portion to the earth. Espectially when handling any micro computer or IC, carefully remove such static electricity before touching them.. 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 t rouble will possibly be caused in the part. 3. B e f o re replacing any parts, be sure to turn o ff 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 re s u l t. 4. During replacement or repair of a part, c a refully handle it : The printed circ u i t b o a rd has fine lead wires (jumper wire s ) and glass-made parts (diode) on its substrate. So if a circuit board is roughly handled, such lead wires and parts will be easily b roken 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 c o v e red with an oxide film, solder cannot a d h e re to the lead wires if not polished. 6. When soldering any part, care should be e x e rcised not to apply any high-wattage 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 pro p e r t i e s 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 t r a n s f e red to the entire object to be sold e red. If the solder pieces are not well fused due to insufficient transfer of the heat fro m the soldering iron, no satisfactory electrical continuity can be assured even if the sold e red objects appear well connected to each o t h e r. 8. The solder used should be limited to a minimum. If excessive solder is used, it will cause inter-pattern contact, which may cause malfunction of the circ u i t Procedure The parts should be replaced in the following pro c e d u re. 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. 5-8 Samsung Electronics
