check the resistance by tester [see table 1]
check the resistance by tester [see table 2]
check the resistance between two terminals [see fig.2,table 3]
adjust proper temperature in remote controller
check the resistance by tester [see table 2]
check by eyes
check proper voltage of power supply and use an exclusive power supply
check proper voltage of power supply and use an exclusive power supply
check the restarting operation of compressor, after passing 3 minutes
if the scale of the tester swings instantly to "zero
Ω
" and does
not move back to "infinity" , capacitor for compressor should
be replaced [NOTE.2]
other than described above
other than descrived above
check the pressure of refrigerant gas [see 「 performance curve diagram 」 ]
if the scale of the tester swings instantly to "zero Ω " and does
not move back to "infinity", capacitor for TAG fan motor should
be replaced [NOTE.2]
other than described above
leak of gas, or cut off of overheat prevention relay
check the wiring order(NO ROTATION)
check the wiring order
change PCB (main controller)
check by eyes and clean it
check the voltage between blue and yellow in connector [see fig.3]
check the resistance by tester [see table 1]
after starts operation, if TAN fan rotate properly by hands,
capacitor should be replaced
check the resistance by tester [see table 2]
check the resistance by tester [see table 1]
check the blockage of air outlet of TAN
check the blockage of air inlet & air outlet of TAG
check the pressure of refrigerant gas [check 「 performance curve diagram 」 ]
other than described above
check the pressure of refrigerant gas [check 「 performance curve diagram 」 ]
check the blockage of air inlet & air outlet of TAG
check by eyes after power off. turn by hands and check noise
check by eyes around the pipes with any obstacles
if DC5V is achieved between black and brown portion of lead wiring of fan
motor, while no voltage of pulse between white and black wiring, then TAN
fan motor should be replaced
UNDER "POWER SAVE" MODE (NOTHING ABNORMAL)
check the voltage between 2 and 4 in terminals [see fig.5]
check the voltage between 2 and 4 in terminal [see fig.5]
check the current at wiring 1 by clamp meter [see fig.4]
