6-3 Sequence of trouble shooting for inverter aircon OPERATION START • The indoor unit does not work even though the power is plugged. • There is no sound "DING" • The lamp is not on the display. Check the indoor unit control board. (A) The indoor unit does not work when operated by the remocon. Checking the Remocon.(B) Check the control board and display board of indoor unit.(C) The 2 digit part of indoor LED display shows Error Code and the unit stops several minutes after the indoor uint starts.
Troubleshooting 6-3-1 (A) Check of indoor unit control board √ Unplug the power cord and plug it after 5 seconds. √ Press the on/off switch located indoor unit inside to operate the air conditioner. ◆ • If the air conditioner operates, check the remocon and indoor unit display board.
Troubleshooting 6-3-4 (E) Check of indoor unit fan motor ■ ■ ■ ■ 1. √ Check whether the wires are connected surely between control board(CN72) and running capacitor(Tab). 1. √ Check whether the wire of fan motor is connected to the control board (CN73,CN74) of indoor unit. 1. √ Check whether the error mode displays after the strong rotation for approximately 15 seconds since air conditioner turned on. 1. √ • In case the error code displays after the fan motor is rotating for 15 seconds.
Troubleshooting 6-3-7 (H) Check the defrost temperature sensor and outdoor temperature sensor. √ Connector of outdoor unit control board (PIN#1,2 of CN51 - outdoor temperature sensor),(PIN#3,4 of CN52-deice Temperature sensor) Measure the resistance between two wires and if it is same as follows, it is normal but if not, replace it. Ambient temperature (°C) 15°C 20°C 25°C 30°C 35°C 40°C Resistance of thermistor [KΩ] 14.68 12.09 10 8.31 6.94 5.
Troubleshooting 6-3-11 (L) Check of instantaneous over-current protection of IPM circuit. √ Inverter instantaneous over-current protection mode is the mode to be actuated in order to prevent the damage of elements from the peak current of IPM circuit elements. √ In case that the inverter circuit instantaneous over-current protection mode actuates.
Troubleshooting 6-3-13 (N) Check of the heatsink temperature abnormal rise √ If the air flow around the heatsink on the control box is not good, heatsink temperature will go up and the control box will have damage. So controller check the heatsink temperature and protect at the cirtain limit. Possible troubles are fan motor trouble, fan motor drive circuit trouble and air flow blocking.
