Three weeks ago the temp control began blinking and food was warming. I swithched off the fridge and opened the panels and found a lot of ice. i left it to defrost overnight. It began to work the next day.
Three weeks later, the same problem.
Please advise what the problem may be and how to fix it.

Re: Samsung Fridge side by side
It sounds like you have a defrost problem. This will either be the defrost heaters the defrost thermostat or defrost timer. In order to check the heater if you are competent enough you can check that you have resistance across the heater. Alternatively you can rotate the timer (normally in the fridge section abov the thermostat control) around to a defrost cycle (you will normally hear a click) and check to see if the defrost heater kicks in. Please note the cabinet has to be cold in order for the heaters to work. The defrost sensor should also have zero resistance across the terminals when the coil is cold. Please do no attempt the above unless you are practically skilled. A good fridge guy should be able to quickly identify the problem and remedy it. Defrost heaters are generally the first part to fail. Hope this is of some help.

first run the diagnostics on the unit from the tech sheet inside the unit,then if thermistors are bad replace these there are 2 one on the left and one on the right wall in both fridge and freezer,if good per diagnostics then replace the electronic damper door located between the fridge and freezer compartments in the upper left hand corner of the fridge behind the plastic grille as these doors break and jamb open or shut and the temps can no longer be regulated during the diagnostics tests you can hear this door operate if its operating correctly,lastly,if these fail to solve your problem,replace the main control board in the back behind a panel

The fridge gets its cold air from the freezer through a vent(damper)
between the freezer and fridge.The fan in the freezer blows air through it.
Make sure this fan is running. You may have to hold the door switch in for it
to run. There is a flap you adjust with
the fridge temp. control. Make sure it's opening and closing when you adjust
the fridge temp. The problem could be the electronic control if
you have one or the mechanical linkages.
have actually been having the same problem. We have a Maytag MTB2156GEQ
and it hasn't been cooling well at all lately. Temp in the fridge is
about 52 degrees even on the highest setting. The freezer seems to be
fine. I pulled off the back panel and vacuumed out the condensor coil
and everything else under there. I then pulled out the control panel on
the ceiling of the fridge. The channel between the freezer and fridge
was almost completely blocked with ice. I cleaned it out by taking out
the back panel of the freezer and pouring hot water down through the
hole until it was clear. that seem fix the issue.
What happens is the defrost is controlled electronically from a circuit board, when this goes bad, the freezer quits defrosting, and freezes the fans that circulate air through the fridge side of things.
To check this, unplug the entire fridge, leave the freezer open, wait for it to defrost a bit, if this causes the fridge to start cooling again when you plug it back in, then its the defrost. You should also see ice crystals on the back of the freezer just under the icemaker.
