PROBLEM POSSIBLE CAUSE REAMEDY
Service cord unplugged Plug in elctrical outlet.
No power at outlet Check proper voltage availability with multimeter.
Relay and OLP
Using starting coard, check compressor direactly If compressor
starts, check relay,and OLP individuall with multymeter and
replace onc one found to be defeactive .If compressor doesn't start
replace compressor.
Improper Electronic board
connection
Check for board connection if not connected properly then connect
as per wiring diagram,If there is any Physical damage then
replace the board.
Loose connections Check circuit from power source to compressor.
Motor winding Check winding resistance for proper values.If found defeactive
then replace.
Compressor stuck Try starting with starting cord. If compressor won't start ,change
compressor
Moisture restriction
Characterised by heavy frost around eveaporator inlet,Heat frosted
area If frost line moves farther along coil after heating restriction
was properly caused by moisture Freeze up .Discharge unit
evacuate, using system procedure and recharge.
Permanent restriction First check for moisture restriction, check for crimped or damaged
tubing. Repair or replace leaking component.
Low charge or no charge Check for leak. Add leak charge if necessary to get internal
pressure. Repair leak, or replace leaking component.

High ambient and/or
abnormal usage
On initial Pull-down in high ambient,the compressor may cut
off on overload,instruct customer
Low or high voltage
Check voltage with voltmeter.voltage at outlet should be 198V
to 260 V AC at the moment of start, low voltage may cause
false starts.high voltage may cause compressor to overheat.
Relay and/ or OLP Replace the defective part.
Compressor motor winding
Shorted Overcharge
Check for winding resistance, Replace compressor if found
defective .check for high wattage and frosted suction line
.Evacuate and recharge with correct charge.
Compressor stuck Change compressor
Thermistor &
potentiometer.
(a) Set too warm
(b) Thermistor not properly
located
(c) out of calibration or not
functioning
(a)Turn knob to clockwise towards colder side.
(b)See that thermistor is properly located.
( c) Check potentiometer and thermistor resistance .It should
be between 0-22 K
Interior air circulation:
(a) Evaporator fan
(b)Restriction in ducts
(c ) Air control open too
wide
(a) check eveaporator fan .Replace if defective
(b) Check for and remove obstruction in ducts.
Abnormal usage Instruct customer
Bad door seal or door not
closing
Adjust door to obtain proper door seal instruct customer to
make sure door closed completely.
High ambient Locate in area out of direct rays of sun and away from heat
registers or other sources of heat.
Cabinet lights Check to make sure door switch is closed. Replace ,if
necessary.
Excessive frost on
evaporator Check items under complaint, "incomplete defrosting "
Freezer fan switch Check for proper closing of Freezer switch, Check for freezer
switch connection.Replace if found defecticve

Check items under complaint,
"compressor runs but no refrigeration. Or
insufficient refrigeration."
Frezzer/ Refrigerator comprtment too
cold.
Thermistor & potentiometer
(a) Set too cold
(b) Thermistor not properly
positioned.
(c ) Out of calibration or not
functioning
Turn knob to anticlockwise towards warmer
side .Ensure proper positioning of the
thermistor Replace if necessary.
Door seal Adjust door for proper door seal.
Vold in insulation voids are not likely to occur within cabinet
wall.If in acassible area, fill it with fiber glass.
Abnormal usage Instruct customer to cover foods and liquids.
door seal
Check door seal and and adjust the door,if
necessary instruct customer to be sure door
closes completely.
Insufficient air circulation
Make sure return air flow is not
resistricted.Increase cold air flow by operating
refrigerator compartment as cold as possible
without freezing food.
External sweeting
Internal sweating
Incomplete defrosting or high
temperatures during defrosting
Check thermistor defrost control.Check
resistance of thermistor as per specified value
or check loose fittment of freezer thermistor
may cause the defrost heater to stay on too
long.change thermistor if found defective.
Freezer thermistor
Defrost heater
Check defrost heater with
ohmmeter.Inoperative defrost heater will result
in frost and ice accumulation on evaporator.
Replace if defective.

customer how odour and tests of food in refrigerator
can be absorbed by ice cubes in freezer due to
internal air circulation.

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
