1.2 Appliance description The Side-by-Side appliance is a 1 compressor Freezer–Fridge w ith automatic evaporator defrost. The appliance w orks by means of a 230VAC / 50Hz pow er supply, the temperature inside the appliance is regulated by means of tw o sensors (one inside the freezer and the other one inside the fridge). The appliance is controlled by tw o electronic boards (see chapter: 2). Air Flow A fan, mounted in the air duct draw s room air into the unit compartment through the right side of the front base grille (A), through the condenser (B), and around the compressor (C). lt is then forced into the exhaust duct (D), w here some of the w arm air is exhausted out holes in the rear (E), but most of it goes forw ard through the duct, passing over the defrost evaporation tray w here it evaporates any w ater in the tray. Inside the refrigerator, cold air is distributed to the freezer and refrigerator compartments by a fan mounted in a fan shroud at the rear of the freezer compartment, just above the evaporator. The fan air up through the evaporator w here it is cooled.

Inside the refrigerator cold air is distributed to the freezer compartment, just above the evaporator. The fan draw s air up through the evaporator w here it is cooled. The cold air is delivered to the freezer through a cold air outlet about halfw ay up at the right rear of the freezer compartment, and through louvers at the top rear of the compartment. Freezer air is returned to the evaporator for re-cooling through louvers in the low er part of the evaporator cover. Cold air enters the refrigerator compartment at the upper left side, near the back, by means of an air passagew ay through the divider w all betw een the freezer and refrigerator compartments. Refrigerator air is returned to the evaporator for recooling through an air passage at the low er left side of the compartment, near the rear.

� Motorised air baff le � Evaporator fan (only w hen the air baff le is open)

3.2 Evaporator Defrost Cycle The defrost cycle starts w hen:

- the compressor runs(effective running time) for at least 8 hours;

- a door w as opened since the last defrost cycle;

- 50 hours passed since the last defrost cycle;

- both doors are CLOSED until the time of 50hrs. Termination of the evaporator defrost cycle:

1. Standard function sw itches OFF

2. Freezer over temperature alarm is OFF

3. Compressor and both fans(compressor + evaporator) sw itches OFF

4. The air-baff le/damper sw itches into the CLOSE position

5. The heater starts to heat the evaporator w ith the follow ing timing:

5 minutes ON � 1 minute OFF 3 minutes ON � 1 minute OFF and so on until point 6. takes effect

6. The evaporator bimetal thermostat reaches the opening temperature(+7°C �3°)

7. The heater sw itches OFF

8. Both fans sw itches ON, the compressor fan after a elapsed time of 7 minutes and the evaporator fan after a elapsed time of 10 minutes.

Service manual


4. Icemaker 4.1 How does the ice maker work? Water is automatically measured into the ice makers mould by a solenoid-operated w ater inlet valve. The Bimetal thermostat mounted betw een the support housing (see draw ing below ) and the mould detects the w ater / ice temperature. When the ice is cooled dow n to about – 9°C, the thermostat sw itches the ice maker motor and the ice maker heater ON. The motor and the ejector blades begin to rotate. The ejector blades rotate about a quarter until they are on the ice. The ice is frozen hard in the mould so the motor w ill stall on the ice and apply pressure through the ejector blades. During the stall period the heater is w arming the mould to loosen the ice. This may take a few (up to f ive) minutes. When the ice is loosen, the ejector blades and the motor completes the rotation and remove the ice from the mould. The w ater valve solenoid sw itches on again, to inject fresh w ater. The ice w ill be collected in an ice container f itted in the door. 4.2 Ice control system Once during every injection cycle, the Ice control system (Emitter / Receiver � see also chapter 8 troubleshooting) detects the Ice level into the Ice container.

Ice control system EMITTER (the emitter is placed on the left side of the freezer compartment underneath the ice maker)

Service manual


Ice control system RECEIVER (the receiver is placed on the right side of the freezer compartment underneath the ice maker)

When the ice container is full, the Ice control system detects the ice and prevents the system to overf ill it. The ice maker start a new cycle of ice making w hen the ice volume rises dow n. Attention: The ice maker’s eff iciency is determined by the temperature into the freezer compartment. The temperature inside the freezer should be minimum -12°C or colder, to reach a quick making of ice cubes. Once installed, the f irst required action by the customer is to dispose the f irst container loads of produced ice cubes. They could be discoloured or have a bad taste and odour caused by a new plumbing connection. Ice cubes stored in the ice conveyor bin w ill absorb any odours w hich are in the air inside the refrigerator and freezer. Ice w hich is more than one w eek old:

� The old ice cubes may transfer a stale, musty odour to the new made ice cubes and the ice bin.

Improper w rapping of foods in the refrigerator and freezer.

� Hidden odour from spoiled food / dried food spills. Food odours w ill settle into ice cubes if allow ed to circulate in the airf low of the refrigerator.

Ice made w ith bad w ater quality.

� If the ice cubes are made w ith bad w ater quality, a w ater f ilter must be installed.

4.4 Functioning of the icemaker

Start of the freezing cycle The mould is f illed w ith w ater. The thermostat is in open position. All components are pow erless. ATTENTION : the shut off arm is replaced by the Ice Control System (the function is the same as described in this chapter)

Start of the ejection cycle The thermostat closes at about -9°C. The mould heater and motor are on pow er.

Service manual


After a few degrees of motor rotation the timing cam sw itches the holding sw itch from C-NC to C-NO. This assures the completion of the cycle. The mould heater remains to on pow er through the thermostat circuit.

When the ejector blades reach the ice in the mould, the motor w ill stall. The motor remains in this position until the ice has thaw ed loose. During this time the mould heater remains to on pow er.

Service manual


The ejector blades eject the ice cubes from the mould. The Ice Control System detects the ice into the Ice container positioned in the door and the shut off sw itch sw itches from C-NO to C-NC. The mould heater is on pow er.

The thermostat opens at about 0°C. The mould heater is sw itched off. The motor remain on pow er.

Service manual


After about 5/6 of the complete rotation of the ejector blades the w ater valve sw itch closes and the w ater valve solenoid is on pow er (Voltage divider: mould heater – solenoid) The w ater valve opens and w ater refills the mould. The ice cubes are dropped into the Ice container.

After a few degrees further of the motor rotation the Ice control system sw itches the shut off sw itch from C-NC to C-NO. When the ejector blades are again in the start position, the holding sw itch sw itches from C-NO to C-NC. The motor is sw itched off.

Service manual


4.5 Water fill adjustment The quantity of w ater is time regulated and is serial adjusted to 7,5 seconds, that estimates 125 ccm w ater. When the small hole is centred in the larger hole (see picture 1) the w ater f ill adjustment is for 7,5 seconds f ill time (normal). Turning the w ater level adjustment screw (see picture 2) moves the contact in relation to the contact ring segment (see picture 3). turning the screw clockw ise = decreases w ater f illing turning the screw counter-clockw ise = increases w ater f illing A complete rotation (360°) effects a f illing of 40 cm³ w ater (~ 2,4 sec.) A half rotation (180°) effects a f illing of 20 cm³ w ater (~ 1,2 sec.) A T T E N T I O N : only one rotation is possible. Further adjustment could damage the module! If the adjustment screw falls out, just put it back in and align the hole in the sight hole as show n in picture 1.

If the Ice container is full w ith ice, the Ice control System detect them and the shut off sw itch remains in the C-NC position. Follow ing cycles w ill NOT start until the Ice Control System detects that the Ice cube level is to low in the Ice container in the door.

5.6 Basics and benefits about

� the w ater f ilter and � the iced w ater dispenser

Cold surfaces, such as ice, absorb bad odour faster than w arm surfaces. In this case there are a lot of reasons for bad odours and tastes in your ice w ater or ice cubes: After the installation of a new refrigerator

� clean the Ice bin

� rinse the iced w ater tube and reservoir by dispensing a few litres of w ater through the dispenser.

Good reasons to install a water filter system:

� fresher Ice

� reduction of bad tastes and odours

� helps to reduce lime(calcium) build up in the w ater system

� reduction of chlorine, dirt, rust and other micro particles

8.3 IDI SERVICE DIAGNOSTIC or How to test the IDI (Ice Dispenser Control boards) The service diagnostics mode checks only the function of the optical system (Receiver & Emitter). To enter this mode, open the f reezer door af ter the main pow er applied for at least one minute. The status LED should f lash tw ice, then pause for 1 second, then repeat this sequence as long as the door is open.

Service manual


If the user pushes on the emitters f lap door, the optics path should be cleared, and the LED should be on solid. The service diagnostics mode cannot be entered if the icemaker is in the middle of an ice making process. To determine if the icemaker is in the ice making process, press in the door sw itch and look at the status LED. When the door sw itch is pushed IN during a ice making process, the status LED w ill f lash ON and OFF one pulse every second. If the IDI control is in the diagnostic mode it cannot enter the ice making process mode. How to test the IDI (Ice Dispenser Control) boards w hen installed in a product: 1. The icemaker must not be in the park position

(ejector f ingers pointing on 2:00)-(factory side built in w ith the f ingers on 12:00). 2. With the f reezer door closed apply pow er to the product (thus to the IDI boards). This

initiates the pow er up diagnostics procedure. 3. Open the f reezer door and check the diagnostic LED.

(f rom the time that pow er is applied to the IDI board you have one minute to check the results of the pow er up diagnostic procedure). The status diagnostics LED should be ON (continuous for 5 seconds) indicating that everything is ok.

IDI error codes are as follows:

• 2 f lashes, 1 second of f – then repeat the tw o f lashes:

� indicates an optics problem

• 3 f lashes, 1 second of f – then repeat the three f lashes:

� indicates the icemaker is not present (could be caused by the icemaker being in the park position).

• 4 f lashes, 1 second of f – then repeat the four f lashes:

� indicates the relay on the receiver board did not close.

(the receiver board is defective and must be exchanged). When you open the door and the system detects more than one (multiple) error codes you w ill see the f irst error code. Then you have to f ix the f irst error and repeat the test to see if there are any other problems.

Icemaker Diagnostic ( optical indication )

Preparation for the Service Diagnostic:

Step 1: Fix the emitter flap with a tape in closed position and close the door.Step 2: Switch of the icemaker on the user board.Step 3 :Open the freezer door.

(The technician will then have 60 seconds to open the freezer door.)Step 4: Hold the light switch to simulate a closed door.Step 5: Switch on the icemaker on the user board.Step 6: Listen to the receiver LED output code.

(After opening the freezer door, the technician has 2 seconds to see the code.)

LED output failure indication:

2 flashes, 1 second off , 2 flashes again: Indicates an optical problem Solution: Change the IR Receiver

3 flashes, 1 second off , 3 flashes again: Indicates an icemaker fault Solution: Change the icemaker

4 flashes, 1 second off , 4 flashes again: Indicates an defect relay Solution: Change the IR Receiver

If the LED is solid on for min. 5 seconds, everything is correct working.

Note : If the system detects more then one error code, you will see the first error code.Then you have to fix the first fault and repeat the test, to see if there exist anyother problem.

Check with a leakage spray allsoldered places or measure thepressure in the cooling cycle.

If there exist a leakage or there is not enough cooling gas inside,make the repair to the present valid regulations ofcooling cycles.

25


The appliance does not cool at all

Reason: The thermo - fuse is open.

At every plug in, the product starts with the ”defrost phase” and if the fuse or the defrost-heateris in “open circuit” condition, the appliance remains in that state.

Procedure how to check ,if the thermo - fuse is good:1. Unplug the appliance2. Remove the rear panel3. Open the main control board box4. Disconnect only the 12-pole connector.

With a multimeter check the ohm value between the two following points:Blue wire ( Pin 1 ) of the 12-pole connector (disconnected) and brown wire ( Pin 1 )of the16-pole connector (connected).Between the two points we have to found the ohm value of the defrost-heater ( 83-94Ω ).If the result is “open circuit”, that means the thermo fuse is defect or there exist a bad connectionor a wire problem. Than you must check the connectors and the wires

16-pole connectorPin 1 brown cable.

12-pole connectorPin 1 blue cable.

Resistant value must be between83Ω and 94Ω !

35

Reason: The capacitors in the mainelectronic board is loosing capacity.

Change the main board and follow thedescription described in theService Bulletin: FRG-TI2005-03-modification of the lower hinges-GB.pdf


Rattling noise from the appliance.

27


Temperature alarm always on.

Possible reason: Evaporator completely iced.Possible reason:Gas leakage.

Check with a leakage spray allsoldered places or measure thepressure in the cooling cycle.

If there exist a leakage or there is notenough cooling gas inside, make therepair to the present valid regulationsof cooling cycles.

Thermofuse & bimetal Defrost heater Main Board

Could be theresult of defect….

Check the resistancevalue of the heatingelement. It must bebetween 84-94 Ω

Bimetal check: There must me a electricalcontinuity between the orange and white wires.

Thermofuse check: There must me a electricalcontinuity between the brown and blue wires.

If everything is checkedand correct working,you have to change theMain Board.

Check if water drops out from the waterout coming tube ( top ) for the ice maker.

In this case, the valve does not closeComplete by particle like rost etc.Therefore you have to change the valve.

Check if there will be taken toomuch water quantity every cycle.

If yes, follow the instruction bellow toadjust the water quantity filling.

Water fill adjustmentThe quantity of water is time regulated and is serial adjusted to 7,5 seconds,that estimates 125 ccm water.

When the small hole is centred in the largerhole (see picture 1)the water fill adjustment is for 7,5 seconds filltime (normal).

Turning the water level adjustment screw(see picture 2) moves the contactin relation to the contact ring segment (seepicture 3).

Turning the screw clockwise= decreases water fillingTurning the screw counter-clockwise= increases water filling

A complete rotation (360°) effects a filling of40 cm³ water (~ 2,4 sec.)A half rotation (180°) effects a filling of 20cm³ water(~ 1,2 sec.)

Note : Only one rotation is possible. Further adjustment could damage the module !If the adjustment screw falls out, just put it back in and align the hole in the sight holeas shown in picture 1.


Ice water presence all around the ice maker.

39


Ice formation on the freezer bottom.

Reason: The membrane on the outcoming tube to the drip trayis loosing ( falling down ). In this case warm air with humidity enterinto the freezer compartment and cause the ice formation.

Check the correct position of themembrane, as shown in the picture below.

40

Reason: Wrong position of the Bimetal - and Safty – thermostat,placed on the evaporator in the freezer compartment. If thesurface is looking to the evaporator ( down ), the defrost cycle istoo short and not complete finished. Therefore we have the riskof compl. ice formation on the evaporator ( isolate ). That meansnot enough cold air is coming to the fridge compartment.

The picture below, shows you the correctposition of it. To avoid a rotation of this part,fix the cable of it with wire stripes.

Fix the cableat this place.


Temperature in the fridge compartment too warm.

41

Sensor channel

Reason : Air leakage in the rear side of the multi flow channel.The adhesive tape does not close the channel of the sensor

complete. In this case we have a direct air circulation betweenthe both air channels left and right side to the sensor channel.

( see the picture below ).
