Is compressor current higher than current
protection limit? Is current sensing circuit in good
condition?
detecting circuit is
abnormal. Replace
outdoor PCB
replace power module
start
yes
no
if compressor is normal
Is pressure normal?
connect firmly
Are power cables L, N and
compressor wires U, V and
W properly connected
correctly?
Is compressor winding resistance
acceptable? Is it stuck?
no
if rectifier is normal
Are capacitance and conductivity
values of electrolytic capacitor
acceptable?
9) Over current protection
Is supply voltage too low?
Especially when compressor runs
at a high frequency.
Modify power supply circuit
yes
yes
no
no
no
no
no
1. Is module output voltage among U, V and W
balanced?
2. Disconnect all terminals. Is resistance of the
power module between P and N; P and U, V, W; N
and U, V, W acceptable?
yes
yes
yes
yes
replace compressor
1. Check diode characteristics of rectifier+, AC; - AC
2. Measure voltage between P and N, which should be 310VDC at 220VAC.
After compressor runs, the value should reduce
Replace electrolytic capacitor
yes
no
Check: 1. Is a valve in system close?
2. Is piping clogged;
3. Is system overfed; is there air in system;
4. (Cooling cycle) Is condenser dirty? Does outdoor fan motor run at
low speed or stop?
5. (Heating cycle) Is evaporator or filter dirty? Does indoor fan motor
run at low speed or stop?
6. Is ambient temperature too high? Is system overloaded?
