CONTROLS & ELECTRONICS CONFIGURATION:
Top Mount: Deluxe models:
This refrigerator is managed by an Electronic System, mainly consisting of the components:
• Electronic ontrol Board (Hercules- Dlx (BEE))
• POT (Potentiometer) in case of Dlx (BEE) models only.
• Temperature Sensors {refrigerator, Defrost}
• ompressor ( With Run capacitor)
• Freezer Fan Motor (A )
• Defrost Heater ( Integrated Al tube 200W)
• Door Open Sensing
These components are described as shown below.
– Electronic Control
The complete operation of this product is done by the Electronic ontrol, Functions of this models
are fully controlled by the Micro-controller I which executes the functions according to the needs,
turning the components On or Off through received/managed signals, such as:
- ompressor On/Off
- Defrost Heater On/Off
-Temp setting in refrigerator ompartment, through received signals by the POT along with the
R & F Sensors Temp. Feedback.
-Door open sensing / Alarm
- Among many other functions controlled by its software.

9
The Electronic ontrol is located at the rear of the refrigerator, next to the cabinet and besides the
ompressor, inside a plastic box. ables 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.

10
Identification of connectors:
CN1 (Connector 1)(6 pin MLX) – ompressor, Heater and Power ord
CN (Connector )(8 pin minifit) – Temperature Sensors/POT
CN3 (Connector 3)(6 pin minifit) – R /F LED
WARNING
Electrostatic Discharge Risk
Do not touch the ircuit components, because you can damage fuse/burned or weaken the board.
Always handle the Boards by the sides/plastic holder.

Disassembly Procedure of coreboard box:
1. Disconnect the Power cord from the Mains supply.
2. Remove the Mounting Screws and connectors.
IMPORTANT
# Be careful when using the Multimeter measuring probes, as they may damage the
onnector terminals.

Cooling control:
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 product goes into defrost (in thermostatic mode) 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 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.
5. If there is no door opening up to 8 hrs of compressor running than defrost time will be 18hrs
6. 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.

13
Safe mode routine
During onstant fault condition, the Electronic ontrol will assume a safety routine, as in normal
cycle, trying to keep food conservation, however will work as follows:
• ompressor 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 ompressor activity
• Every defrost time is fixed for 20 minutes. No dependency on defrost sensor for ut Off temp
of 15°
Note: -
•There is no Service routine provided in this model.
•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 F 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 after 3 minutes of heater getting off. 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 F Plenum.
•In case of any Aluminum foil wrapping found over the Wiring harness either in F compartment, R
ompartment or in the ompressor 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 F /R
* Potentiometer Failure
1 First Turn Off the Product & disconnect the Plug.
2 Remove the 3 connectors of ontrol Board.
3 For Thermistor Failure F /R
* heck resistance on pin no. 4 & 8 of N2 (8 pin connector) for R Thermistor.
* heck resistance on pin no. 2 & 6 of N2 (8 pin connector) for F Thermistor.
* IF thermistor is open then the resistance is infinite.
* IF thermistor is short then the resistance is zero.
* IF resistance lie between 0-22 KOhms the themistor is OK.
5 Potentiometer Failure
* heck resistance on pin no. 1 & 5 of N2 (8 pin connector) for Potentiometer.
* It should lie between 0 to 22 K ohms
