I have a samsung fridge freezer and it keeps switching itself off?

Its as if it gets to the right temperature....motor stops but doesn't kick back on so obviously things start to melt ....I have to turn it off and on again with the buttons....then the works again....I have re set temperature...not sure what to do ...I'm next it now and it has just clicked off ...not clicking back on ...all the power is on its just silent...HELP

Wow it worked! My on/off switch had that metallic growth... scraped it off with a craft knife... fridge works! my fridge is over 10 years old. It took me 3 goes before I found the metallic growth. it looks like a silvery bloom on the side of the switch; a bit like snail trail.

Thanks for this very useful thread. I've been having problems on and off for the past couple of years with myeight year old SR-L39 model. The thing would begin bleeping for no apparent reason and the 'super freeze' symbol would light up. I removed the PCB and found the solder growth on the sides of at least three of the small black plastic micro switch housings, including the super freeze switch. This must have been tricking the brain into thinking the switch was constantly being activated as, once the growth was scratched away, the fridge freezer has functioned without any of the old issues re surfacing.

General problem for SR-L36 and SR-L39 range and how to fix it.
These fridge freezers have a panel at the top which has 6 buttons and a display on it .
In the course of manufacture and over a period of use a little metallic whisker can grow between the two contacts of any one of these 6 switches.
The effect of this is that the electronics in the unit thinks that you are pressing this button at random or holding the button down continuously.
In our case it was the "super" button that was the one where the whisker was causing the problem. As a result it would switch on to "super" and off again. This would be accompanied by a "beep" indicating that it thought a button had been pressed.
When I dissasembled the unit today to identify the problem initially I found that all the switches were showing some level of whisker growth but the "super" button had complete growth between the two pins.
Removing whisker growth restored normal operation.
The effect of whisker growth on each switch will have different effects on the fridge/freezer operation.
This means that whisker growth on the "power switch" would cause the machine to turn on and off at random or stay permanently on or off.
The "super" button would cause the "super" function to switch on and off as described above.
Likewise the "fre. temp" , Ref. temp" and "eco" switch would also cycle on and off or cause the function to stick and stop any of the other buttons working.
If the whisker is on the "VAC" button it will quite possibly inhibit the fridge from working while the freezer continues to run.
Fixing the problem can be done by someone competent to do this sort of thing.
Turn electricity off and remove plug.
Remove panel at top of appliance by two screws and deforming plastic at top.
Disconnect plugs to Printed Circuit board assembly (that supports switches) making note of how to reconnect.
Remove this assembly from moulding.
(the light switch may be in the way so take this out first)
Remove metal switch board strengthener.
Remove long switch Printed Circuit Board from computer Printed circuit board.
You now have the switch and display assembly printed circuit board.
If you look VERY carefully at the side of the switches ( little square thing with button on top) then between the pins you will see little "silver" whiskers that look like a silver coloured lichen growth.
You need to carefully scratch this away with a sharp knife.
Ideally the switch needs desoldering to ensure it is clear of whiskers underneath as well.
Look at all the other switches to ensure another one is not about to give trouble as well.
Reassemble and hopefully all is now well
