Freezer keeps building ice on coils temp light blinks

SOURCE: SAMSUNG RS253BAWW NOT WORKING

the ice maker wont cycle untill the temp of the ice is around 10 degrees so if the freezer is at 15 or 20 due to some other malfunction then you will see the maker full of ice but it wont harvest and make another batch. so you could have a sensor bad, control malfunction, refrigeration issue, compressor, defrost system malfunction(you mentioned ice build up)

Hey how yo doing? on most refriderator there are two important parts to keeping freezer from freezing over, they are the bimetal thermostat and ice pipe heater. The bimetal therostat is a preset thermostat that ranges from 54degrees farenheit to about 60, when the coils (inside the freezer compartment behind the back panel) reach the preset temp. it closes a circuit and send electricity to the ice pipe heater, to warm the freezer coils preventing from freezing over. if any one of those components fail, your freezer will continue to freeze solid until there is no more space for ice to build on coils decreasing air flow from the evaporator fan blowing air into your fridge.To test you will minor knowledge on using a multimeter.(REMEBER TO UNPLUG REFRIDGERATOR BEFORE SERVICING, IF YOU UNCOMFORTABLE WORKING ON APPLIANCE PLEASE CONTACT A PROFFESIONAL REPAIR SERVICE..) If you'd like to continue please respond.
GOOD LUCK, WORK SAFELY..

Hey how's it going? I may have the info you need, but first I need you to go through a check list to see if there is a simple fix.
Check to see if there are any obstructions in the freezer drain (freezer drain located inside freezer compartment behind back panel lower right hand corner of the freezer coils) if there are obstructions or debris remove and clean with a mild dish washing detergent and water, check to see that water can drain freely. see if this helps.when the coils freeze is the ice flaky or is it frozen solid ice? if the ice is flaky it could mean that either the refridges/freezer door are left open to long "check your door gaskets or seals by closing the on a dollar bill if it pulls out easily with little to know resistance your door gaskets may need to be replaced. After you defrost the freezer coils did you notice if there was water in the condensor pan, if so good sign. (condensor pan: is the pan that collects the water that drips through the drain hole of the freezer compartment caused by the heating of the coil by the coil heater: water that enters the pan collects and is reused by the condensor fan by blowing warm air partly into the water and through the condensor coils causing them to cool.)if you still need to test your bi-metal therostat or your glass heater/ice pipe heater, you will need a multimeter and knowledge on the use of it.(IF YOU 'RE NOT NOT COMFORTABLE AROUND ELECTRONICS AND ELECTRICITY PLEASE CONTACT A QUALIFIED REPAIR SERVICE AND REMEMBER TO UNPLUG APPLIANCE BEFORE ATTEMPTING ANY REPAIRS) for more info on how to test please reply,Good Luck, be safe..
