Top Mount : Deluxe models: -------------------

This refrigerator is managed by an Electronic System, mainly consisting of the components:

•

•

•

•

•

•

•

Electronic Control Board (Nilgiri- Dlx (BEE))

POT (Potentiometer) in case of Dlx (BEE) models only.

Temperature Sensors {refrigerator, Defrost & POT(Dlx)}

Compressor ( With Run capacitor)

Freezer Fan Motor (AC)

Defrost Heater ( Integrated Al tube 245W)

Door Open Sensing

These components are described as shown below.

– Electronic Control

The complete operation of this product is done by the Electronic Control, Functions of this models are fully controlled by the Micro-controller IC which executes the functions according to the needs, turning the components On or Off through received/managed signals, such as:

- Compressor On/Off

- Defrost Heater On/Off

- Temp setting in refrigerator Compartment, through received signals by the POT along with the RC &

FC Sensors Temp. Feedback.

- Door open sensing / Alarm

- Among many other functions controlled by its software.

The Electronic Control is located at the rear of the refrigerator, next to the cabinet and besides the

Compressor, inside a plastic box. Cables going inside the product, using connectors that do not permit an assembling failure do its connection to the mains and its components.

Note: For more details see Wiring Diagram.

WARNING

Electrostatic Discharge Risk

Do not touch the Circuit components, because you can damage fuse/burned or weaken the board.

Always handle the Boards by the sides/plastic holder.

Spare parts/stock boards if outside the BOX must be kept in anti-static packaging.

Assembly &Disassembly Procedure

Disassembly Procedure:

A) Core Board Box

1. Disconnect the Power cord from the Mains supply.

2. Remove the Mounting Screws.

11

3. Release the Cover tabs.

4. Releasing the On board Connectors.

IMPORTANT

# Be careful when using the Multimeter measuring probes, as they may damage the

Connector terminals.

# Be careful when removing the electronic board connectors, as they are latched.

Remove them at right angles with no side movements

12

1. Defrost Sensor mounted on the Evaporator tube.

2. Removing/Replacing the Defrost Sensor

Defrost Temperature Sensor – NTC

It’s located at the freezer compartment, along with the Evaporator. The Defrost Sensor is responsible for sending signals to the electronic control, which will command the ending of the defrost, turning off the Defrost Heater,

This does a similar function to the well-known Defrost Bimetal

IMPORTANT

Never change the position of such Sensors, as their functional characteristics can be modified. This sensor also informs the temperature conditions of the Evaporator when the product is activated (plugged in electricity) indicating to the Electronic Control the correct start up to be followed, for instance, manufacturing ,default or the previous programming done by the user, compressor delay , etc.

WARNING

These Sensors (refrigerator & Defrost) Are Compatible with Each Other, but

Are not compatible with the Sensors of the previous Model (SYMPHONY)

NEVER replace these Sensors with the Sensor Kit used in the Symphony model.

In the need of replacing one of the Temperature Sensors, Replace the full RC/FC Sensor harness (In

these model FC Sensor harness is replaceable). Directly replace the relevant RC or FC Sensor harness. Do not try to repair the harness for the faulty Thermistor.

Adaptive Defrost Control

The defrost cycle shall be started after the Defrost timer has expired. According to the following defrost procedure:

Defrost must be executed every time one of the following event occurs:

1. After 8 hours (+/-10 minutes) of compressor running, calculated considering just the thermostat function.

2. When the compressor stops (in thermostatic mode) and a time period of 20 min (+/-1 minute) is allowed to complete the time to defrost.

3. If the door open time > 10 min, within first 5 hrs of cumulative compressor run time, defrost is initiated at 5hrs.

4. If door open time > 10 min between 5 to 8 hours of cumulative compressor run time, defrost will happen instantaneously.

5. If the door open time < 10 min or If there is at least one door opening up to 8 hrs of compressor running then defrost time is as per point 1.

6. If there is no door opening up to 8 hrs of compressor running than defrost time will be 18hrs

7. If there is no door opening for 8 hrs, & there is door opening between 8 to 18 hrs of compressor running, defrost will take place immediately.

The 5 th

, 8th or 18 th

hr of compressor running (defrost timer) consist of the sum of all the compressor’s ON time, independently of the number of compressor cycles and how many time the compressor was ON.

14

Door Open Sensing Alarm

Door open sensing alarm activates or gives beep if the door is kept open for more than 2 min.

During the Door opening beep alarm if the door is closed then the alarm gets deactivated .

Alarm Codes, Priority, Retention and Trigger

Alarm code for Deluxe models: -

• In event of any Fault accurring for RC/FC or Pot sensors then immediately after 2 min’s of the fault occurrence a Buzzer Beep for 1 Sec will be activated indicating the Sensor fault condition in

Dlx models only.

• To understand where there is any Sensor or Pot failure indication in the Dlx model, Service Person should Switch On the Product & wait for the any buzzer Beep if any after 5 sec of Product switch

ON. This will indicate the Error status in the Dlx models.

Check Point:

- Poor contact between terminals/ connectors – CN2 (Temperature Sensors) at Electronic Control

(main board)

- The Sensor/Pot itself that might be open or in short circuit and has to be replaced (see Sensor/Pot replacement).

Safe mode routine

During Constant fault condition, the Electronic Control will assume a safety routine, as in normal cycle, trying to keep food conservation, however will work as follows:

• Compressor and Fan Motors will be on for 25 minutes and then will turn off for 20 minutes.

• Interval set between defrosts will be fixed in every 5 hours of the Compressor activity

• Every defrost time is fixed for 20 minutes. No dependency on defrost sensor for Cut Off temp of

Note: -

• There is no Service routine provided in this model.

• In Dlx models Diagnosis of the Error / Sensor / Pot failure is not of continuous nature. Service person needs to restart the Product to listen to the Buzzer Beep for error indications if any.

• To check whether Heater is working fine or not, service person can use the Power up initialization function of the model, where Product need to be switched Off & need to be ensured that the temp at the

FC sensor is >0°c, then after making the product ON product goes into the Power up initialization mode where after product switch ON, heater gets activated for the first 5 seconds & then it goes to the compressor mode. Service person can make the use of this 5 seconds where by putting the Tong tester one can easily identify the healthy/faulty condition of the heater through the driving current displayed on the tong tester it self at the Electronic core board box location without opening the FC Plenum.

• In case of any Aluminum foil wrapping found over the Wiring harness either in FC compartment, RC

Compartment or in the Compressor deck area, the same Al foil should be carefully replaces in same fashion after servicing

• In case of any detailed technical information please check with the Dlx technical specification.

Board Level Diagnostics for :

* Thermistor Failure FC/RC

* Potentiometer Failure

1 First Turn Off the Product & disconnect the Plug.

2 Remove the Control Board from Box.

3 Disconnect the 10-Pin connector from Board.

4 For Thermistor Failure FC/RC

* Check resistance on pin no. 8 & 9 of CN2 ( 10 pin connec) for RC Thermistor.

* Check resistance on pin no. 5 & 7 of CN2 ( 10 pin connec) for FC Thermistor.

* IF thermistor is open then the resistance is zero.

* IF thermistor is short then the resistance is above 22 KOhms

* IF resistance lie between 0-22 KOhms the themistor is OK.

5 Potentiometer Failure

* Check resistance on pin no. 1 & 8 of CN2 ( 10 pin connec) for Potentiometer.

* It should lie between 0 to 22 K ohms
