THe fridge is running OK. But the freezer is running @ 50 deg

Hi,

Here is a service manual for the samsung fridge mentioned:

Samsung service manual

Have a look at page 29 to page 34, the section titled self diagnostic's which will explain how to get the system to perform various self checks.

There could also be another section of interest on page 20 and page 31.

I'm not trying to make you **** lemons when you read these sections as they talk about operating controls but I'm just making sure that you havn't accidentally turned something off by accident.

Feel free to have a browse through but there iis a lot of information regarding how to take the fridge apart which i really doubt you need to do or would want to do.

Two problems I think. How to check everything

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.


AND

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.
