4. Malfunction of Over current Protection E5

Yes

End

Yes

Malfunction is
eliminated

Is the supply voltage unstable
with big fluctuation?

Is the supply voltage too low
with overload?

The fan is abnormal? Fan
speed is too low or fan doesn’t rotate

Measure the
current of the main board
with a clamp ampere meter. Is the
current higher than the value of the
overcurrent protection?

Is there blockage inside
the system? (Filth blockage, ice plug,
greasy blockage

Is the compressor running
abnormally? Is there abnormal sound or oil
leakage; is the temperature of the shell
too high, etc.?

Is the indoor / outdoor
heat exchanger too dirty,or are the air inlet
and outlet blocked?

Normal fluctuation is within 10 % of the rated
voltage on the nameplate

Malfunction is
eliminated

Troubleshooting
for E5 malfunction

Adjust the supply voltage to maintain it within
normal range

Clean the indoor and outdoor heat exchangers
and remove the blockage of air inlet and outlet

Check the motor and reinstall the motor to have
the fan run normally

Replace the mainboard

Replace the mainboard with the same model

Flush the heat exchangers with high pressure
nitrogen

Replace the mainboard with
the same model

Yes
