Question about Refrigerators

1 Answer

I have an RL33SBSW fridge freezer, for the last week the lights on the control panal have been flashing & the fridge has been freezing all the food. I was told it needed a PCB which I purchased and fitted, the lights have stopped flashing and the fridge has stopped freezing but now it isn't getting cold in the fridge. The outside of the fridge freezer used to get warm too and that is also not happening now. The appliance is only 13 months old, please help.

    I have the same Samsung RL33SBSW fridge-freezer. It is only a few months old. The lights on the control panel started flashing about a month or so after purchaing it. I have turned the power on and off on a couple of occasions. This has stopped the lights for a brief period, before they start flashing again.

    I presume I should call the Samsung engineers to fix this problem, given that it's still under warranty?

    I have the same problem. The lights are not the issue - But has started to freeze for the fast week or so. No frost at the back of the fridge yet BUT - YES the fan seems to running every time you close the fridge or Press the light button by hand..
    Help any one.. ?
    the changing the PCB sounds complicated.

    do you have any air coming through the vent in the refrig ? is the fan in the freezer running? do you have frost accumulated on the back wall of the freezer?

Good day..
I would Double-check the part.. before I did anything else.
I would recheck my model no. just to make sure I was right.... I would want to find out if the part I was sent is the one it is supposed to be... it probably is.... It may seem silly, but it happens more often than it should.
When a Refrigerator doesn't defrost like it should, a common condition would be to hear that some foods in the frig side freezing, why, is because the control which cycles both freezer and frig, is located in the Fresh food side, there is not enough air movement to cycle the thermostat, so it runs all the time. Cold air drops, and usually the freezing occurs down below in the veg. drawers and/or vent ports involving air transfer between the two compartments... as more time passes... ice on evaporator thickens, air flow circulation reduces even more, now conditions begin to reverse.. and exactly what you state above begins to occur... look inside your Freezer, the back wall... you'll see ice (like a snow-cone) forming.. if so... you could have a defective PCB, I doubt it.. 95% probability, it's the bi-metal termination thermostat.. the other 5% would be your def heater. I have found more PCB prone to be at fault under these circumstances then that the thermostat.. I wouldn't toss out that PCB... If you keep this unit for a long time, it will be the likely thing to be needed, in the next round..
