Hi guys - hoping you can help me out with what appears to be a common problem for the samsung french door fridges.

 

Water builds up under the cool pantry tray.  This is the third time it has happened.  There is so much water that we noticed it because it drips down to the floor.  Some of it even ices over.

 

What I have done every time up to this point is take all of the shelves out, remove the inside back panel that covers the evaporator/heater assembly. Then I use a hair dryer and warm water to melt the ice that has clogged the drain at the bottom of the evaporator/heater asembly.  After the drain is clear, I reassemble everything and hope it doesn't happen again but like I said this is the third time so I'm losing hope! It is usually a couple months before it freezes over again.

 

I've read about this issue all over the internet but I have not found a solution to the problem.  Seems like the heater is good or their would be ice build up on the evaporator and their wouldn't be any water.  Hoping you guys have the answer!

 

By the way, I ran a self diagnostic and just get a fully lit 88 88.  I assume that is telling me everything is good.

 

Thanks for any help you can provide.

 

George

I would remove the acess panel at the rear of the fridge near the compressor and make sure that tube isn't clogged with dust or debris at the end. It should be a white tube with a black piece of rubber on the end. You may want to put a thermometer in there to see if it is running well below zero as well. I've seen them run down to -11 and -20 on another one.

First off, thanks for the reply.  Just want to make sure I understand what you want me to do before I do it.

 

You want me to pull the fridge out of the cubby hole its in and remove the exterior panel on the fridge that covers the compressor area and check the white tube with the black rubber cap.  Is this where the drain that is on the inside below the evaporator/heater assembly empties into?

Yes it is. If something in the tube slows the flow down it will make it freeze. I have found a ball of dust just inside the rubber piece. You may have to pull the tube off because sometimes it has a black duck bill inside of the tube.

Great. I'll have to take care of that tomorrow.

Just out of curiosity if things are working properly and the water from the defrost goes down the drain and all the way through to the tube, how does it leave the tube?

Gravity?  There is usually a pan of some sort shape and size that the water drips into, and the heat produced from the compressor will evaporate what water is in the pan.

Might also check to blocked air passages inside the styrofoam f/f evaporator cover.  If blocked with ice you can clear it by running hot water into vents.  Might also replace f/f defrost sensor (yellow wires).  Should help prevent some callbacks on those nuisance Samsung drain problems.

ok I went ahead and moved the fridge and took the back panel off.  There were two tubes in the back. I'm assuming one for the fridge and one for the freezer (?).  Pulled both out.  They are about 9 inches long.  The one on the right side (looking at the back) was a little wet and little dirty.  The one on the left was dry. Both tubes were debris free.

Should I go ahead and put a hair dryer to the frozen drain in the fridge and see if the water goes all the way down to the tray?

Ok I went ahead and used the hair dryer and hot water. This cleared the drain. I poured some water into the drain and it went down the tube and into the defrost tray at the bottom of the unit. By the way, the tube on the right is the one for the fridge.

I then ran a manual defrost and it defrosted properly so I am assuming the problem is the sensor. Looking at the manual I believe the sensor part # is DA32-00027B. Would someone please confirm that this is indeed the correct part # so I can go ahead and order it?

Any other suggestions?

Thanks!

According to repair clinic that is the humidity sensor.

Yeah I noticed that but every other site calls it the defrost sensor.

Thanks for replying.

They may be one and the same. You will have to find out the resistance tolerances and test it. Or you can test voltages drop across the sensor at the control board. You will need the service manual for that info..

The heat probes on the Samsung don't go deep enough into the drain tube to prevent them from icing over, you can modify whirlpool part#819043 to replace existing heat probe or use Samsung part# da61-06796a (or make your own) The defrost sensor (thermistor) failure usually causes incomplete defrost causing ice build up in evap cover and around fan. If your primary problem is leaking try the heat probe.

Here's the service manual for this model:  http://appliantology...service-manual/

 

Back on pg 87, there's a parts breakdown and listing for the freezer.  DA32-00027B is attached to the evaporator and is the evaporator thermistor.  Why RC calls it out as a humidity sensor, I don't know but I've seen then call parts strange things before.  

 

Here's the Whirlpool heat strap that Brother JJ mentioned:  http://www.repaircli...p/819043/726493

Went ahead and bought the whirlpool heat strap. That makes a lot I sense as to why the drain hole freezes over.

Thanks for all of the help!
