Samsung SR-S2026CVW fridge condensation and high freeze temp

[Yellow Message]

Hi all

I have a 7 year old unit which recently started to suffer excessive condensation in the fridge about 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time, especially under the lower shelf. The ice-cream in the freezer also started to suffer!

The front panel diagnostics had no lit segments – so it thinks all is well.

Cycling the power, the freezer/fridge could chill from room temp to their set temps in under 2 hours. After several hours, the temps seem to creep up again and I caught the freezer at -5C on one occasion. I suspect a defrost or sensor problem.

I investigated behind the rear panel in the fridge compartment, there was a slight build up of ice on the fins and the drain looked clear of ice. The defrost heater resistances read 2k3 and o/c (does the main heater have a thermal trip in series? Or is it bust?).

Any ideas what is wrong?
What voltages do the heaters use? It is damp in there and I cannot believe they are mains powered!
Is there a way to force a heater test from the front panel?
More info on typical sensor resistances/temps would be useful.

Thanks for any advice you can offer.

Re: Samsung SR-S2026CVW fridge condensation and high freeze

After the deluge of replies 😉 , here is what I have done.

In the fridge compartment I replaced the defrost sensor (black version – the white ones are prone to failure) and put a new heater into the evaporator assembly. If you twist the fins you can work your way along the old heater tubing and remove it. The new heater is secured if you bend the fins back again.

The freezer temperature still varies by about 5C° but at least it stays in negative double figures. The condensation in the fridge is much better as there is only occasional light moisture, as it has always done from new.

Hope this helps somebody out there!
