Haier BD-103GC, Service Manual

runs without 
stop, 
temperature 
in freezer is 
too low 

been set to “over cooling” position. 
2.The contacting point of temperature 
controller is adhered. 
3.The temperature sensing probe of 
controller is not placed well, and causes 
maladjustment 
4.Compressor efficiency reduced. 

moderate. 

2.  Repair or change. 
 
3.  Adjust to suitable position, 

normally contact tightly with 
evaporator cover. 

4.Change compressor. 

Compressor 
buzzes and 
cannot be 
started, 
thermal 
protection 
unit jump 
repeatedly. 

1.  Voltage is too low. 
 
2.  Starting relay out of order. 
3.  The starting coil of starting motor is 

broken. 

4.  Compressor does not run. 

1. 

Supplement a stabilizer, 

adjust to rated value. 

2.  Change starting relay. 
3. Change 

compressor. 

 
4.The shaft and piston in the 
compressor is blocked, please 
change. 

After short 
time of 
operation, 
over load 
protection 
unit cuts off 

1.  The voltage is too high. 
2. Over load protection unit is not good, it 
jumps earlier. 
3. Starter contacting point is adhered. 
4. There is short circuit in compressor. 
5. There is mechanical problem in the 
compressor. 
6. Temperature around compressor is too 
high. 

1.  Supplement a stabilizer and 

adjust its value to rated. 

2.  Change over load protection 

unit. 

3.  Change starting relay. 
4. Change 

compressor. 

5. Change 

compressor. 

6.Increase heat radiation space. 

Too much 
noise when 
compressor 
runs 

1.  The floor is loose. 
2.  The freezer body is not stable and in 

level. 

3. When compressor runs, friction 

between tubes and freezer body causes 
resonance. 

4.  Compressor fixing screw is loose. 
5.  The vibration absorption cushion for 

compressor fixing is too tight, or too 
loose or ageing. 

6.  Compressor inside noise is too big or 

vibration absorption suspending spring 
is broken. 

1.  Reinforce the floor. 
2.  Make the freezer body stable.
 
3.  Move the tube a little away to 

avoid friction. 

 
4.  Make the screw tight. 
 
5.  Adjust the degree of tight or 

loose of vibration absorption 
cushion, or change cushion. 

6. Change 

compressor.  

There is no 
frost at 
evaporator 

1.  There is serious leakage of 

refrigerant. 

2.  There is dirt blocked the capillary or 

system. 

1. 

Check leakage, make 

welding repair, and fill 
refrigerant again. 

2.  Clean the capillary or change 

filter. 

Frost at 
evaporator is 

1.  There is some leakage of refrigerant. 
2.  There is dirt block, but not serious. 

1. Check leakage, make welding 
repair, and fill refrigerant again.
