Problem Diagnosis; Troubleshooting - HEC HFN-136 Manual De Instrucciones

Ice and frost form on the surface of evaporator during
operation. A thick layer of ice or frost acts as heat
insulation and hinders thermal conduction.
Defrost the freezer compartment in the shortest time
possible to avoid thawing of frozen foods.
Do not remove the ice or frost in the freezer
compartment with a sharp or pointed item. Otherwise
the evaporator surface may get damaged.
Wipe off defrost water from time to time with sponge.
Place a container of hot water (do not use boiling water)
near the door of freezer compartment to speed up the
defrosting process.
Dry the freezer compartment and place the frozen food
back.
Reconnect the refrigerator after defrosting.
Start up the refrigerator by adjusting the temperature
control knob.
Close the door of freezer compartment.

12. Problem Diagnosis

The latest manufacture techniques and state-of-the-art
refrigeration and freezing technology are adopted to
ensure safe and reliable operation of your appliance. In
doubt of fault, make sure to check first as described below
before making a service call:
Things to be noted:
The compressor (also known as refrigerating unit) doesn't
operate all the time without stop.
The compressor is
temperature regulator represented by a temperature dial.
When the interior temperature exceeds the preset
temperature, the compressor starts automatically and
when the interior temperature falls below the present
temperature, the compressor stops automatically.
It's normal that compressor makes noise during operation.
The noise comes from the motor. The flow of refrigerant
through the refrigerating system may make a gurgling
noise. These noises don't mean a fault of the refrigerator.
The exterior surface may be wet when it's cold and the
ambient temperature is low. It's normal and the exterior
surface will become dry as the ambient temperature rises.
If the reasons of such phenomena can't be identified and
solved, please consult the service center.

13. Troubleshooting

a) Problem: Refrigerator does not operate (does not
work)
Please check:
Is the power cord in good condition? Is the refrigerator
properly plugged in the outlet?
Is there a power interruption? (Use a small appliance to
check out, e.g. agitator or hair dryer)
controlled by the automatic
Is the refrigerator started up? (The temperature dial
should not be set at "0".)
Is the fuse broken? Or in poor contact?
b) Problem: The inner compartment is not cool
enough; the compressor cycles on and off
frequently;
Please check:
The refrigerator/freezer compartment should stand still
for at least 2 hours after installation to stabilize the
refrigerant circulation system. See "Start-up". If it
doesn't work, unplug the refrigerator and tilt the
refrigerator to one side for a while or place it on an
inclined plane and then place it to the original position.
Connect the refrigerator after 2 hours. Keep the door(s)
closed for 12 hours.
Is the door properly closed? If so, the door gasket
should press on the external cabinet securely and
evenly.
Test: It should be difficult to pull out a piece of paper
caught up between the door gasket and the external
cabinet.
If the paper slips away easily, consult the service
center.
If there is thick ice in the freezer compartment. (See
"Cleaning and Maintenance")
Is the refrigerator exposed to direct sunshine or near a
heat source (oven, radiator, etc.)?
What to do: Do not expose the refrigerator to direct
sunshine; keep the refrigerator away from any heat
source; install
refrigerator and the heat source (see "Location").
Is the inner compartment overloaded?
Is the room well ventilated? Is the air vent obstructed?
Is the heat exchanger (condenser) on the back
covered by dust?
c) The temperature of refrigerator compartment is
too low
Please check:
Is the temperature regulator properly set?
Is the door of freezer compartment properly closed?
Is there a lot of fresh food (more than 1kg) in the
freezer compartment? (If the freezer compartment
operates for
refrigerator compartment falls accordingly.)
d) The freezer compartment is too warm and frozen
foods are thawed
Is the ambient temperature too low? (If so, the
refrigerating unit will malfunction, resulting in higher
temperatures in the freezer compartment.)
What to do: Raise the ambient temperature.
