Haier HFN-248, HFN-136 manual Problem Diagnosis, Troubleshooting, Please check

yIce 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.

yDefrost the freezer compartment in the shortest time possible to avoid thawing of frozen foods.

yDo not remove the ice or frost in the freezer compartment with a sharp or pointed item. Otherwise the evaporator surface may get damaged.

yWipe off defrost water from time to time with sponge.

yPlace a container of hot water (do not use boiling water) near the door of freezer compartment to speed up the defrosting process.

yDry the freezer compartment and place the frozen food back.

yReconnect the refrigerator after defrosting.

yStart up the refrigerator by adjusting the temperature control knob.

yClose 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 controlled by the automatic 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:

yIs the power cord in good condition? Is the refrigerator properly plugged in the outlet?

yIs there a power interruption? (Use a small appliance to check out, e.g. agitator or hair dryer)

6

yIs the refrigerator started up? (The temperature dial should not be set at “0”.)

yIs 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:

yThe 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.

yIs 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.

yIf there is thick ice in the freezer compartment. (See “Cleaning and Maintenance”)

yIs 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 a thermal barrier between the refrigerator and the heat source (see “Location”).

yIs the inner compartment overloaded?

yIs 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:

yIs the temperature regulator properly set?

yIs the door of freezer compartment properly closed?

yIs there a lot of fresh food (more than 1kg) in the freezer compartment? (If the freezer compartment operates for long periods, the temperature of refrigerator compartment falls accordingly.)

d)The freezer compartment is too warm and frozen foods are thawed

yIs 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.
