[. . . ] Yes Fan motor is defective No Indoor PCB is defective No Repair the connector Failure phenomenon Indoor room temp. or evaporator sensor is open circuit or short circuit Operation lamp Timer lamp On Is connection to connector good?Yes Replace the sensor No Repair connector Page 14 of 33 Failure phenomenon Over current protection of the compressor occurs 4 times Operation lamp X Timer lamp Operation lamp off and Timer lamp flashes After changing the main control board, check if the failure releases. No The voltage of power supply is too low (less than 187V)? Yes Yes Indoor PCB is defective Yes Power supply fault No Outdoor unit fault (such as the compressor) Failure phenomenon EEROM error Operation lamp On Timer lamp EEROM error, indoor PCB is defective. Failure phenomenon No over-zero signal Operation lamp Timer lamp This is alarm signal when the main chip can't detect over-zero signal. When such failure occurs, the main control board must have fault. 7. 2 Outdoor unit Failure phenomenon Stand by High temp.
