Temperature in ref not cold took off the flow thru from freezer and it is blocked with ice I now need to get the cover on the inside of the ref to remove the ice from this side I can get it loose from the front but can't seem to get it loose in the back

*** The following is for information only.***
* Original question was slow ice making or melted ice;:
* Most common is ice build up in freezer coils. This happens every time the door is opened. Ice builds up on coils but is normally removed during a daily defrost cycle.
* The cycle may be unable to defrost all ice due to bad air circulation. Usually caused by rubbish blocking fan intake (bottom of freezer tray or wall.) Overloading food may cover the intake.
* Remove all food from freezer. Check for fan blockage. There should be a steady flow of cold air. If not then your freezer needs to be defrosted.
* Defrost by moving all frozen food to fridge side or cooler. Unplug fridge and open freezer door (drawer). Allow room air to circulate into the freezer. Use a house fan to blow air into freezer. (DO NOT use Hair dryer! It will damage panels.)
* Check and remove melted ice water. Check inner panels of freezer. Once defrosted the panels will be room temperature to the touch. There should not be any condensation or coldness to the panel. If it's still cold then keep defrosting.
* Once the water stops dripping. then close freezer doors.
* plug in freezer and wait 5 mins. Check freezer if inside is cold and the air is blowing cold. Reload freezer with food, take care not to overload or cover fan intake. Monitor for 2 days.

You do not have enough air flow. make sure you do not block the vents inside the freezer and also around the outside of the freezer. It needs to extract the heat from inside to keep it cold. If you have no air flow, in and out, ice will build up.

The defrost thermostat is not working and the evaporator compartment is blocked with ice. That will stop cold air from entering into the fresh food compartment.
Move your food to another refrigerator, then unplug and open the Samsung refrigerator for 24 hours and allow the ice to melt.
Then remove the freezer panel inside and locate and replace the little plastic tube like part that is zip tied to the expansion tubing. It should have 2 brown wires coming out of the plastic sealed tube/ thermostat part. Write down your model number and go to Samsung's website or searspartsdirect and buy a new thermostat.
I believe the operating range for said thermostat is 20 C to -5 C. you'll most probably have to cut the wires and splice in the new thermostat. You can also use a generic thermostat with the same or nearly the same ratings of 20/-5 C temp.
All the thermostatic switch does is control the defrost heating element that melts the ice off the evaporator every 10 to 12 hour cycle via the defrost timers switch located at the bottom rear of the refrigerator. You can turn the clock counter clock wise until the first loud click to force the machine into defrost as well. Although if the defrost heating element, thermistor, THERMOSTAT, or defrost timer switch has malfunctioned there will not be a defrost cycle and ice will form inside the ducting and evaporator compartment and block the cold air circulation and the fresh food compartment will not cool and the freezer section will barely freeze water.

sounds like your freezer is not defrosting, causing lack of air flow to fresh food side

DEFROST HEATERS IN THE FREEZER. IF THERE IS FROST ON THE BACK WALL INSIDE THE OF THE FREEZER SECTION. YOU THEN HAVE A DEFROST PROBLEM. REMOVE THAT PANEL AND DEFROST WITH HAIR DRYER. THIS FROST IS BLOCKING THE AIR FLOW TO THE REF. SIDE. AFTER THIS IT WILL WORK FOR 10-21 DAYS WITH OUT REPLACING A PART. THERE IS A BROWN AND ORANGE WIRE TO THE DEFROST SAFTY THERMOST. THE CONNECTOR ON THAT BROWN WIRE MAY HAVE FROZE APART. THE DEFROST SAFETY THERMOSTAT MAY HAVE FAILED. OR CONTROL BOARD MAY HAVE FAILED. BEHIND THE KICK PLATE IN A BAG ATTACHED TO THE BOTTOM OF YOUR REF. CABINET IS A TECH SHEET ON HOW TO FORCE A DEFROST TO CHECK THE SYSTEM.

Refrigerator or freezer is not cold enough check this part:

* Check the temperature setting
* Assure that there is enough room for air flow in the refrigerator or freezer
* Check for air flow restrictions in vents
* Test the temperature control
* Clean the condensor coils
* Check the door seals
* Test the door switch
* Test defrost heater
* Test defrost timer
* Test evaporator fan
* Check for a clogged drain tube
* Check for refrigerant leak

One posibility is that it is not defrosting a all and that the ice is building up on the evaporator coil behind the rear cover inside the freezer. This condition will block the flow of cold air. Remove the back panel to see what your have. Either no ice , light frost, partial icing or heavy icing blocking the fins. Complete light frosting is normal.

drain is blocked in freezer. take back panel off inside the freezer and you will probably find that the bottom is covered with ice. melt off with a hairdryer and hot water till water flows freely down the drain. needs a bit of patience

change the adaptive defrost board located in the upper right corner of refrig under the panel. remove panel by pulling on panel towards you from the finger holes in the rear. remove two 1/4 inch screws and two phillips screws. defrost manually with hair dryer behind panel in freezer.
