5 System Operation and Maintenance
Solution
1. Check the compressor
status.
2. Refill refrigerant.
3. Replace the compressor
drive board or compressor.
1. Check whether the input
power is within the normal
range.
2. Use an oscilloscope to check
whether the waveform of the
power grid is within the
normal range.
3. Replace the compressor
drive board if it is faulty.
1. Check whether the input
power is within the normal
range.
2. Use an oscilloscope to check
whether the waveform of the
power grid is within the
normal range.
3. Replace the compressor
drive board if it is faulty.
1. Check whether the fan speed
of the outdoor unit is
normal.
2. Check whether refrigerant in
the system is insufficient,
which causes the outdoor
unit fan to operate at a low
speed.
3. Check the installation
environment of the outdoor
unit to see whether the heat
dissipation of the outdoor
unit is poor and whether the
outdoor unit is blocked.
4. Check whether the fins of
the outdoor unit are
polluted, which causes the
air intake volume of the
outdoor unit to be small.
1. Check the compressor
status.
2. Check the connection status
of the compressor and the
