CAUTIONS AND INFORMATIONS
In case of following troubles, the cause is not related with the failure of refrigerator.
Please mention the correct way to the customer for the use of refrigerator when the repairing.
1. Some foods freezed in the refrigerator compartment.
Do not place food directly in front of cold air outlet.
This may lead to the food freezing.

OUT
2. Some plastic parts were cracked or splitted.
Some household cleaning chemicals may affect the internal food liner and plastic parts resulting in splitting or cracks occurring.
When cleaning all plastic parts inside this refrigerator, only use diluted dishwashing liquid(soapy water). Make sure that all plastic parts are thoroughly rinsed with water after cleaning.
3. Water leaked on the floor.
Make sure the back end of Evaporating pan rests securely on the rail.

When refrigerator temperature control sets to the " ", some foods stored may become frozen. In this case adjust control set back to the " " position.
NOTE:
For hot summer conditions (about over 35˚C ambient temperature), set your Freezer temp. control knob to less colder than " " (towards " "). This is because " " setting may result in too little air flow to the refrigerator compartment, causing too warm temperature in the refrigerator compartment. And set your
Refrigerator temp. control knob to colder than " ".
In a cold kitchen (about under 10˚C ambient temperature), set your Freezer temp. control knob to " " to avoid too warm temperature in the freezer compartment. This is because the compressor operation is too short in winter, and not enough cold air is provided to the freezer compartment. And if the foods in the refrigerator compartment freeze, you must set the Refrigerator temp. control knob to less colder setting.
(toward " ").
With the Freezer temp. control knob set to " ", there will be less cold air directed to the refrigerator compartment, and the refrigerator compartment may not become cold enough.

2. DEFROSTING
(1) No defrosting operation is necessary.
No defrosting operation is necessary.
As this machine is so designed that a built-in evaporator cools air and a fan circulates cooled air, neither the freezer nor the refrigerator is frosted, though Evaporator is frosted.
The frosted Evaporator is defrosted automatically due to the function of defrosting timer and heater, requiring no defrosting operation.
(2) Where is melted frost brought.
1. Melted frost is brought into Evaporating pan at the back of the set and is evaporated here by the heat of compressor.
2. Be sure to use Evaporating pan as inserted so as to be level with the outer case.
(3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with timer and defrosting thermostat.

(4) As a reference to determine the causes of trouble, malfunction and phenomena are described below.
Refer to the following when repairing.
1. Disconnection of Defrost heater
As off-cycle defrosting is performed, the defrosting time is extremely prolonged.
Each time defrosting is started, the freezer temperature rises and a portion of ice and stored foods are melted.
2. Melted Thermo. fuse or opened-circuit due to the defect of Defrost thermostat.
When the above mentioned trouble occurs in cooling operation, the timer motor does not run, defrosting will not take place, and consequently freezing is caused.
In the above mentioned condition, when the timer shaft is turned by hand to defrost, the timer motor runs during the operation time. However, the motor stops from the time when the contact is changed, and freezing causes.
NOTE:
As Thermo. fuse assembly is intended to prevent dangers, do not use it under shorted condition even for a short period.
3. When Defrost thermostat failure causes the circuit to remain closed.
The thermostat assembly connected with Thermo. fuse in the same way.
A portion of ice or stored foods are melted when Thermo. fuse is worked.
3. DEW PREVENTION
The hot pipe, namely D.P.-condenser, is arranged around the flange part of cabinet and the C-partition plate, preventing dew from being generated on the cabinet.
NOTE:
D.P.-condenser pipe may be felt hot if touched by hand while the compressor is in operation.
If you are asked about this, please explain that the hot pipe serves to prevent the dew generation.
Hot pipe
Fig. F-7
4. INSPECTION OF INITIAL STARTING
(1) Inspection of cooling unit
1. Set the temperature control knob to "MAX" and check that the compressor starts to operate.
2. Depress the door switch to run the fan and check that cool air is blown out of the cold air outer of the freezer and the refrigerator.
3. When the compressor does not work, check that the timer is not set to "defrost" position.
4. It takes about an hour and a half or 2 hours to put food in the refrigerator after starting operation.
NOTE:
After return the temperature control knob to "MED" position.
When the refrigerator is operated initially after installed,the compressor may vibrate excessively for 1 to 2 min. However, vibration becomes normal if it is continuously operated.
(2) Inspection of defrost device
Operate the refrigerator for 20 to 30 min. and then check the defrost device in the following procedures :
Allow 5 min. to restart the compressor since immediate starting after stopping will cause unsmooth operation.
1. Turn the timer shaft clockwise with a screw driver.
At this time, make certains the timer clinks and the compressor stops.
2. After more than 5 min., turn the shaft further to operate.
Make certain cooling operation is started again.
