Cooling in Freezer Only in Frost Free Fridge is due to improper fuctioning of defrost cycle in the refrigerator, which can be due to

1. Faulty Bi-Metal Sensor
2. Fauly Defrost heater
3. Faulty Thermostat
4. Faulty Temprature Sensor
5. Faulty Programmed Control Circuit Board (PCB)
6. Faulty Defrost Timer

1. Main tip from our Team is, If any customer keeps on using faulty refrigerator, one fault leads to another fault, resulting in increase in cost of repairing,
   So, whenever there is less cooling in refrigerator, Shutdown the refrigerator and
   Please feel free to call us
2. Keep the thermostat setting of the refrigerator according to the season and keep a check on it regularly

Single door fridge or Direct Cool Fridge starts overcooling when Thermostat is Faulty

Double door fridge or Frost Free Fridge starts overcooling Thermostat is Faulty

Single door Fridge/Direct Cool Fridge: Compressor stops wroking due to following reasons:

1. Thermostat is faulty:Thermostat is used to control the cooling temperature of fridge (when temperature is high than desired set temperature, thermostat gives power supply to start the compressor.Now when temperature is achieved or temperature is as low as desired set temperature thermostat cuts off the power supply to the compressor & as soon as temperature rises above the desired set temperature, thermostat again starts the compressor). When internal electrical contact gets brunt out, or the sensor stops working it does not give power supply to start the compressor.
2. Overload relay is faulty: Overload protection relay is used to protect the compressor against voltage fluctuation & overloading of compressor. Incase if there is high volatge fluctation & customer does not switch off the fridge, overload protection relay might get brunt out & it does not give supply to compressor.
3. Compressor starting/running relay is faulty:Compressor start/run relay is used to give start to the compressor (Fridge compressor electric motor is a permanent capacitor start/run type motor. In this type of motor it is required to create a 90 degree phase shift of electric current between running winding & starting winding to run the motor & compressor start/run relay gives 90degree phase shift). If compressor start/run relay is faulty, compressoor stops working & of it is not replaced on time, compressor overload relay might also get brunt out.
4. Compressor motor winding is brunt out: When compressor motor gets winding brunt out, motor stops working & compressor stops working.
5. Compressor is stuck: Above mentioned all parts are electrical parts of compressor. Now as we come to the mechancial parts of compressor, compressor includes piston running in cylinder head, compressor sucks the low pressure liquid gas through suction/intake valve & compress the gas, & deliver high pressure gas through delivery valve. Now if piston gets stuck in the cylinder head, compressor stops working.
6. Internal fridge wiring is brunt out. Wiring works as nerves to control and supply electric current to the compressor. If wiring gets brunt out, fridge gets malfunctioning & compressor stops working.

1. Defrost timer is faulty: Defrost timer is used to automatically def.rost the fridge
2. Defrost heater is faulty bi-metal sensor
3. Programmed Control Circuit Board(PCB) is faulty
4. Thermostat is faulty:Thermostat is used to control the cooling temperature of fridge (when temperature is high than desired set temperature, thermostat gives power supply to start the compressor.Now when temperature is achieved or temperature is as low as desired set temperature thermostat cuts off the power supply to the compressor & as soon as temperature rises above the desired set temperature, thermostat again starts the compressor).

If compressor start/run relay is faulty, compressoor stops working & of it is not replaced on time, compressor overload relay might also get brunt out.

1. Compressor is Faulty
2. Refrigerant/Gas Leakage
3. Refrigerant/Gas choking
4. Faulty Elecrical Control Equipment i.e.defrost timer, defrost heater, Bi-metal sensor or PCB etc.

1. Compressor is Faulty
2. Refrigerant/Gas Leakage
3. Refrigerant/Gas choking

1. Check the compressor for its proper functioning and ensures if there is any water in the suction line of Compressor
2. If there is water in compressor, compressor has to be replced
3. And if there is no water in the compressor, freezer is replaced along with filter, capillary tube and suction pipe
4. Then leakage testing is done to ensure there is no leakage in the system
5. Then Technician vaccuumm the system fully
6. Refrigerant/Gas is Charged to the proper level
