repeatedly. 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
not full
1. There is some leakage of refrigerant.
2. There is dirt block, but not serious.
3. Refrigeration quantity of compressor
is reduced.
1. Check leakage, make welding
repair, and fill refrigerant again.
2Clean the capillary and filter.
3.Change compressor.
Evaporator
frosts too
rapid, frost
layer too thick
or frozen to
ice
1. Food put into freezer contains water.
2. Too much food has been stored.
1.
Please let or make food dry
after cleaning, then store it.
2. Store only corrects quantity of
food.
Electricity
leakage of
freezer body,
you will feel
tingle when
touching by
hand
1. Freezer body has not been connected
to the ground.
2. The compressor terminal contacts body
shell and causes short circuit.
3. When the components of electrical
system get wet, insulation ability is
dropped, electricity leaks.
1. Make the ground connection as
stipulated.
2. Change compressor.
3. Check carefully step by step, if
insulation is seriously damaged,
please change; remove wet parts
and put them into drying box to
make them dry.
Electricity
leakage of
fan
1. Environment temperature too high or
insulation ability of insulator is dropped.
2. There is short circuit between fan
coils or the fan coil is burned.
1. Change fan.
2.Change fan.
Fan too noisy
1. The blade of fan is blocked or fan
supporter is loose.
2. The clearance of fan axle is too big.
1. Clear obstacles around the fan
or tighten the supporter.
2. Change the fan.
