Samsung side-by-side fridge freezer model RS21DCSV. Freezer is fine. Temperature keeps changing in fridge varying from 5-14 degrees and water has stopped coming out of dispenser. Have checked and everything seems hooked up ok

The settings are "relative". Someone with this fridge in Montana may need to run the same fridge with different settings than someone in Texas to get the same temperatures.

Many manufacturers recommend that the fresh food compartment should be 34 degrees F, and the freezer -10 to 0 degrees F. To set this properly, place a thermometer in the freezer (that can display temperatures as low as the desired temperature). Adjust the thermometer for the correct freezer temperature before going on to the fridge. A fully stocked freezer could take 12 hours or more for temperatures to stabilize after making changes to the thermostat. Once the -10 to 0 degree temperature has been achieved, set the fresh food compartment temperature.

Place a thermometer (that can display below freezing) in a 6 (or so) oz flexible plastic cup of water and place on a shelf in the fridge. A glass of water could break if the temperature gets below 32 degrees if the water turns to ice. The water acts as a buffer to rapidly changing temperatures when the door is opened to read the thermometer. If the fridge is "full", allow 24 hours for the temperature to stabilize before making changes.

If the fridge and freezer are empty, changes may be seen in just a few hours or less. Otherwise, wait the 12 / 24 hours for the freezer / fridge compartments.

I hope this helps and good luck!

Every time I select my fridge and freezer temperature from -16 and 3 degrees C respectively it keeps on going back to 20 and 18 degree C. Please assist.

If it's American, the temperature probably reads as fahrenheit. If so, 20 degrees F is 12 degrees F below freezing which converts to only -6.67 degrees Celsius.

Domestic freezers should be set to -17 degrees Celsius (= 0 degrees F), so the beeper is warning you that the freezer compartment is far too warm. If it's working correctly and has the temperature control set correctly, then it should achieve the correct temperature if you leave it for 24 hours and do not open the door nor try to use the ice dispenser. If the freezer is full of unfrozen items and so has to cool those down as well, then it may take even longer to reach the correct operating temperature.

Te operating manual for your appliance will tell you how to set the temperature correctly and whether it's possible to select between fahrenheit and Celsius scales. Most models allow you to set an override on the beep alarm as well. I cannot guide you on this without knowing the exact Samsung model.

20 degrees seems like a good temp for your freezer!!!

The temp for the fridge is about right and -18 for the freezer is ok so check to see if the water filter is plugged, at 8 degrees Celsius is about 18 degrees fht. Which is freezing so the numbers don't add up. 26 degrees below zero on the freezer side is what you want if it that cold it could have frozen the water line.

Try setting it to lower temperature. If that don't work the thermostat is bad.

The instruction book suggests this could be because the freezer temperature is set too low. Mine is set at -20C. It says the water line can freeze stopping water flow. Try reducing the temperature.

On a fridge freezer only the fridge temperature is monitored. In a cold location the fridge might not even need cooling and the freezer would get too warm but the thing won't care.

If the fridge sensor sees it as too warm then it will keep the motor running and the first thing to get really cold is the freezer.

Remember the freezing part is not temperature controlled ion a fridgefreezer.

You have a clogged defrost drain tube. best way is to thaw unit out. Your vents are being blocked so no air flow is pushed down.

try a full defrost first then if it reoccurs you may need to replace the thermistors behind the back wall inside.
