Newer style Samsung French door frosting up in fridge

[schleven]

I have seen a few of the newer style Samsung fridges that have the typical frost buildup in the fridge evaporator area causing the fan to stop and also some with the defrost drain clogged.  I have been using the water leakage kit DA82-01415A and it seems to work in most cases.
I have had two recalls this last week.  Frosting up again within a few months.
One of the model numbers is RF23HCEDTSR/AA. These are the ones that have the icemaker with the freon line at the bottom of it.


One of them had a sever crack at the edge of the ice room and we sealed that on our return visit.  ( i believe there is a service bulletin on that)  Not sure that would cause excess frost at the top of the evaporator in fridge or not.  I have attached a picture of what it looked like when I returned.  This is after I installed the kit a month or so back.


Are there any bulletins that address this issue on the newer fridges?  Any tips?

Hello Schleven,I have seen this same frost pattern a few times,and it looked they all had a drain problem.I would like to find out what caused that to happen.At first I thought it was incomplete defrosting.And then I thought it was the leftover water due to drain plug up condensed on that part of the evaporator.What do you think?May be other technicians have different opinions.

Hi,

I do have the same problem (please see attached picture). My model is RF25HMEDBSR and it is five years old.

I have read somewhere that you can move the sensor to the upper right copper thread. I did that but there is still ice build-up after a few weeks.

Did you guys find any solution to this issue?

The is a group on Facebook and tech on there came up with a solution for this problem.
He adds a extra defrost heat element tapped into the power for the defrost heater using the blue wire tap connectors that pinch on to the brown wires and coats connectors with silicone grease to keep water out.
The Supco defrost heater number SH502 is 18" long and you need to use black wire ties that can handle 250deg F.
