Chigo In the inverter central air conditioner, the compressor is protected as soon as it is started
. Fault phenomenon
The outdoor unit indicator light is on, but the compressor is protected as soon as it is started, showing an overcurrent protection code.
.Fault Analysis
The main causes of this fault are: first, abnormality in the power module or its power supply; second, abnormality in the control circuit; and third, abnormality in the compressor.
.Inspection
The first step is to check the power supply circuit of the power module. First, touch the starting resistor with your hands to see if it is very hot. If so, the relay in the main control circuit may not close, and the starter that has not completed starting will be short-circuited. The large working current generated when the compressor is running has to pass through the starting resistor. Secondly, check whether the filter capacitor (large-capacity electrolytic capacitor) has failed.
The second step is to measure the voltage at each output terminal of the outdoor unit switching power supply. If it is too high, it means that the fault lies in the switching power supply. First, replace the electrolytic capacitor of the wearing parts on the left side of the switching transformer at the same time, and then check other components of the voltage stabilizing circuit.
The third step is to unplug all the connecting wires between the power module and the compressor and test the machine. Measure the voltage between the three-phase output pins of the module. There are left and right voltages between any two-phase output pins and they are equal. Most of them are compression. Otherwise, if any two-phase output pins have no voltage or are unbalanced, it usually means that the power module is damaged or there is a problem with its control circuit.
Methods to further confirm the quality of the power module: Pull out all the connecting wires of the power module, measure the forward and reverse resistance of the opposite terminal of the module, which should conform to the characteristics of the diode, that is, there is a certain resistance in the forward direction and a certain resistance in the reverse direction. The resistance is infinite.
