Note: You can infer from the preceding figures the current of compressors operating at other
frequency bands.
Step 2:
Check whether the compressor sounds sharp or rubs. Compare the sound of the faulty compressor
with that of a normal compressor.
Step 3:
Check whether the electric expansion valves of outdoor units and the 4-way valves can act normally,
and whether the oil return pipes and oil balance valves 1 and 2 are normal. Touch the pipeline next to the
oil return capillary tubes to check whether there is oil flowing.
Check method for each part:
