Question about Refrigerators
I have a Viking VCSB483SS and recently the alarm for high temeperature is sounding (about every day or so) and I have tried reducing the freezer temperature . One thing noticable is that frozen food stays frozen but new packets )(say peas etc) do not go hard with freezing) I took off the kick plate and the condensor tray seems fine with a little water in it and the condenser coils clean. ONe strange thing is that I notice a 24vdc fan at the front (obviously for the condenser coil above the tray is not connected (and I presume never has been since I purchased the house with the refrigerator/freezer)...why would that be ?...the cable and connector are just wound in a coil and not plugged inot anything?
This one is a puzzle. I have never worked on a Viking fridge but if the alarm is coming on it may have something to do with the fan not being connected because that would cool the coil. You might go on line and contact Viking and ask them this question. I don't want to tell you to hook it up and it not suppose to be. good luck

This would usually indicate that some refrigerant gas has leaked out - the effect at certain percentages is to allow the gas to expand too much when it first enters an evaporator (the plate in the freezer that gets cold), thus making it much colder than the thermostat is set too. due to environmental laws you cannot top this up yourself, it must be done by a qualified fridge guy. get him to check for leaks as well, usually they can be fixed if there is one, but a tiny amount of refrigerant can leak out over time with no actual major leak. Try first defrosting completely - occasionally ice crystals can form inside the refrigerant system which may be causing the problem, once defrosted, this water should be dealt with by the filter/drier. Probably still needs refrigerant gas, but is worth trying. once the gas is topped up then ask the guy to check that the freezer thermostat is working correctly - it could possibly be faulty, no way to tell easily without just replacing it or topping up the refrigerant gas first. Hope this helps, please post again if not :)

Sounds like a pc board problem. I have come across many units like these (although I don't know the Samsungs!) which have similar symptoms...it would seem like the freezer gets stuck in "defrost" mode and the ice would melt etc.etc.... In most cases replacing the electronics module solved the problem...in hindsight I have figured out that it was moisture on the pc board components that were to blame! So as a first resort I would locate the main electronics board and use a hairdryer to dry out thouroughly (even if it seems dry!) Also check values for temperature sensors....don't know what the specific values for the Samsung NTC's are, but normally they are in the low kOhm's.... Oshie

The problem is in the defrost system.. You have a defrost heater in your freezer that comes on 3 times a day & melts the frost to keep your freezer frost free. That frost turns to water & runs down a drain & eventually goes to a drain pan located under the unit. On these models the hole for the drain is located directly under the evaparator fan. The drain hole is to far from the heater so the water settles & then freezes around the fan blades causing it to stop spinning. Its that fans job to circulate cold air from the freezer to the fridge, so now all the cold air is staying in your freezer. Last I knew they were workin on a solution to this but you need to contact the manufacturer. A temporary fix would be to unplug & then defrost the freezer by taking out the freezer panel & melting all the ice. Boiling water is effective. When you get the ice gone from around the fan you should be able to see the drain hole & be sure water runs freely down the hole. Put it back together then adjust the front legs of the fridge so the whole unit slopes back slightly causing the water to run back to that drain hole without settling.
