Haier central air conditioning repair case Three-phase electric cabinet type central air conditioner outdoor unit does not work maintenance method
.Fault Phenomenon
The outdoor unit does not work.
.Fault Analysis
Most of them are caused by abnormal three-phase power supply, such as phase loss or wrong phase sequence, and a few are caused by AC contactor not working.
.Inspection
The first step is to confirm that the three-phase power input to the outdoor unit terminals is normal, adjust (exchange) any two power supply terminals and then test the machine. If the central air conditioner returns to normal operation, it means that the Wrong sequence. Because the power supply has a phase sequence, the compressor of some models can only work normally if the phase sequence is correct.
The second step is to check the AC contactor. Watch to see if the bottom coil is charred. After pressing the forced switch, the measured resistance between the corresponding output terminals is infinite, indicating that the contactor is damaged.
The third step is to measure whether there is AC in the outdoor unit signal line for the compressor control. If not, check the compressor drive circuit in the outdoor unit control board.
The fourth step is to measure the resistance between the three terminals of the compressor. Normally, the resistance between the three terminals (several ohms) is equal. If the resistance between two terminals is abnormal, or the resistance between the three terminals is If the values are not equal, it may be that the compressor is damaged.
The fifth step is to check the indoor unit pipe temperature sensor. The resistance value should be roughly the same as the room temperature sensor at the same ambient temperature.
