Common section 

Analysis in this section is used for D.C. Variable Frequency Series. Before analysis, you can diagnose 

according to the code displayed on indoor unit or indicator display on outdoor unit. (Refer to 9.2 Malfunction 

display section). 

Breaker tripped 

or fuse burnt out 

When the breaker is set ON, it will 

trip at once 

When the unit is turned on, the 

breaker will trip in a few minutes 

Measure the insulating resistance 

for grounding to confirm whether 

there is electrical leakage or short 

circuit in the unit 

Insulation malfunction of line or componen 

in the air conditioner. Insulation breakdow 

occurs after radiation, which causes shor 

circuit or electricity leakage. Measure 

insulating resistance or use one-by-on 

elimination method; 

Malfunction of fuse. Replace it. 

No power supply 

Check power supply circuit 

Air 

conditi 

oner 

cannot 

start up

does not response 

after powered on. 

(The buzzer does 

not sound after the 

plug is connected 

and the unit does 

not response after 

the remote 

controller is used 

to turn it on) 

The power plug is not or poorly 

connected 

Controller fuse is burnt out 

Loose or poor contact of transformer 

connection, or transformer malfunction 

Check and plug well plug, make 

loosen contact firm 

Change control fuse 

Secure the wire connection: measure 

the output voltage of the transformer 

and replace it if the value is wrong 

The controller is broken 

Replace the controller 

Remote 

controller does 

not receive signal 

(When powered 

on, the buzzer 

will send out a 

sound, unless it is 

broken) 

Batteries of remote controller are low 

Malfunction of remote controller 

Loose or poor connection of receiving 

head 

Receiving head is broken 

Change battery 

First press the "AUTO" button of the 

manual switch. If there is no response, 

check according to the above method; 

if it is normal after the button is 

pressed, check if the installation 

location and wire connection of the 

receiving head are correct. If correct, 

replace the receiving head, or the 

remote controller.

Note: Malfunction display : blind 0.5s; stop 0.5s, there is 2s' interval between two malfunction displays 

Analysis or handling of some of the malfunction display: 

1. Compressor discharge protection (E4): 

Possible reasons: shortage of refrigerant; blockage of air filter; poor ventilation or air flow short pass 

for condenser; the system has noncondensing gas (such as air, water etc.); blockage of capillary assy 

(including filter); leakage inside four-way valve causes incorrect operation; malfunction of 

compressor; malfunction of protection relay; malfunction of discharge sensor; outdoor temperature too 

high. 

Handling method: refer to the malfunction analysis in the above section. 

2. Low voltage overcurrent protection (E5): 

Possible reason: Sudden drop of supply voltage. 

3. Communication malfunction (E6): 

Handling method: Check if communication signal cable is connected reliably 

4 Sensor open or short circuit (F1, F2, F3, F4, F5): 

Handling method: Check whether sensor is normal, connected with the corresponding position on the 

controller and if damage of lead wire is found 

5. Compressor overload protection (H3): 

Possible reasons: insufficient or too much refrigerant; blockage of capillary and increase of suction temp.; 

improper running of compressor, burning in or stuck of bearing, damage of discharge valve; 

malfunction of protector. 

Handling method: adjust refrigerant amount; replace the capillary; replace the compressor; use 

universal meter to check if the contactor of compressor is fine when it is not overheated, if not replace 

the protector. 

6. System malfunction (H4): 

i.e. overload protection. When tube temperature (Check the temperature of outdoor heat exchanger 

when cooling and check the temperature of indoor heat exchanger when heating) is too high, 

protection will be activated. 

Possible reasons: Outdoor temperature is too high when cooling; insufficient outdoor air circulation; 

refrigerant flow malfunction. 

please refer to the malfunction analysis in the previous section for handling method . 

-41

7. Module protection (H5): 

Handling method: 

Check if the voltage between power module P and N is too low and 

if the current is too high. In normal condition, voltage between P and 

N should be about 320V. 

Abnormal 

Normal 

Check power supply circuit of outdoor unit (if PTC resistance 

rectifying bridge, reactor, capacitance etc. is ok). 

Temperature of power module is too high, 

which causes overheating protection 

Protection is still displayed 

Check if radiating paste is spread 

evenly or radiating sticker is stuck 

well; if screws of power module 

is tightened 

Reinstall power module and 

re-spread radiating paste or 

stick radiating sticker on the 

radiator of power module. 

Confirm the setting status of outdoor unit (cooling) 

Normal 

Poor radiation, heat exchanger 

is dirty 

Remove obstructions 

and clean 

Confirm if outdoor fan motor is running; unplug the 

three connecting wires between U, V, W of compressor 

and power module. Turn on the unit to see if outdoor 

fan runs normally (about 1 minute) 

Outdoor fan runs 

Confirm if there is voltage output and balance of 

voltage between any two phases of U, V and W. 

Outdoor fan stops 

Measure the voltage of outdoor 

fan connector
