my sumsung rt refrigerator works fine until around 7 hours_ it has high temperature fluctuation in its fridge from -13C to -25C if it is set to -19C. when around 7 hours pass, it suddenly stops working. 4 technicians so far has came and have not find the fault after changing defrost sensors and thermo fuse. Now , they say your compressor is faulty without even doing your test!
Check the heater as well. Sometime the heater works suddenly stop in middle if the heater ok replaced ma main board since the unit work in 7hr hr after 7hr defrost time. Means either the heater or the main board can't return by itself unless unplug the unit then suddenly work again. Defrost sensor is for ice build up moslty at thermal fuse easy to check if broken or not so no need to replaced unless totally open
Sir good Day my tanong lang ako. Master Alameda mo to kasi sa mga compressor motor ito makikita. More aware at Alam mo to. Nikita ito sa compressor motor. BLDC among ibig sabihin. Isa pa PMSM. Nikita to say motor nameplate.
Do you know the part number of the PCB board on the frost free Samsung T20 REF.? Here in the Philippines I'm having trouble sourcing the correct motherboard. Thanks for your time
As You say in the video, inverter PBA applies 5 volt DC current through the connector along with compressor rpm information with feedback signal to main PBA. I have a faulty refrigerator of the same type as shown in your vidoe. I tried to measure voltage in that connector between pins marked GND and 5V and I found 0 volt. Could I deduce that the inverter PBA is faulty? (In addition I can say that the led on the inverter PBA blinks only once at the refrigerator's turning on, then it never blinks, remains off. The led on the main PBA never blinks. The compressor remains off as well).
No if your unit still working and cooling properly replaced main board. You can replaced compressor if not cooling properly maybe compressor ot totally compressor weak but if the unit working then suddenly stop in hour then unplug and plug in again and works check heater, thermal fuse and last main board
@@MrGerbee2 Thanks the thermal fuse has been changed. I dont have the map of the board. However, I checked by the R-Room connector that two pairs have 5 K ohm ( which should be correct sensors), one 12 K ohm ( which should be the fan) and one shows continuity( which should be heater working properly).The F_room connecter didnt have any heater related wire ( 2 pairs for sensor and one for fan). I will try one more thing, hopefully it will give me some results. I dont know why but my control board led space is empty. I will solder one led there in order to see if the led blinking gives me any sign of the heater fault. Are there any other way to check the heaters?
@@MrGerbee2 Thank you very much. So I will focus on the heater and if i find it working properly. i would replace the main board( the bigger board not the inverter board)
How to test unmounted inverter compressor without inverter PBA? For example, we buy it through online shop or any offline shop Is it possible to test run the inverter compressor by 220V AC?
Not posible to test in 220v because inverter pcb run on dc voltage and can use only with electronic board... you can check the resistance for all fin with same value but you cant check if the motor wirks normal.

Hello, how do I get the error code / blinking LED? My Samsung Inverter refrigerator has problem. It's not cold enough, meaning that it can not produce ice cubes. Or if I put ice cubes inside the freezer, it will melt down becoming just cold water. I see the LED on the left board is ON steadily, and the LED on the right board is always OFF. Do I need to unplug and replug the power cord in order to get the LED blinking?
Mam very good information
Mam please sensors ke baare m bataye

Gud information
Nice information🙂
dagdag kaalaman na namn salamat sir
and what if all the tests are ok? then is there still a possibility compressor fault?
No if your unit still working and cooling properly replaced main board. You can replaced compressor if not cooling properly maybe compressor ot totally compressor weak but if the unit working then suddenly stop in hour then unplug and plug in again and works check heater, thermal fuse and last main board

@@mahanmahrueyan8806 heater can check by tester or connect to power if 220v and if the heat is ok means heater is ok
@@MrGerbee2 Thank you very much. So I will focus on the heater and if i find it working properly. i would replace the main board( the bigger board not the inverter board)
@mahanmahrueyan8806 yes the bigger board. Small board for compressor controller as long as your compressor run properly in hour means it's ok

INVERTER PBA SUPPLIES 5 VOLT DC THOUGH THIS CONNECTOR
WHAT COLOR OF CABLE DO YOU CHECK?
All pin going to compressor
@@MrGerbee2
Do you mean the three cable to inverter compressor have 5 DC volt each other?
Where do you find Samsung Repairs videos for other components?
Here in youtube you will find some video in repair for all brand.

Hii i wanna talk to you
sir okey po ba 13.4 , 13.4 , 13.2
It seems Samsung make a cost saving on my fridge cause main board has no LED even when the PCB has the schematic and the label on it!!!
How to check for models without test but one example for samsung model
What do you mean without test?
Teen bar Bling kar raha hai kya problem hai
🤟👍👌
Please Please stop the music loop.
Saan kaya makakahanap ng fan motor nyan...12volts...

Not English may hindi speaking
my fridge is blinking twice on the inveter board and 10 times on the power board
This error is compressor not run..but not compressor problem..most of samsung inverter unit has pcb problem or the inverter board
@@MrGerbee2 the compressor is running for secs then stops
Greet thank u

what was the fix?
@@B.D.TRX4 it's not fixed yet :-( I called some technicians but I wasn't convinced of their proposed solution.
