Here's the other post I was referring to http://www.justanswer.com/appliance/66u0h-samsung-refrigerator-model-rb1855sl-bottom.html
I just pressed and held the bottom two buttons for 3s. Nothing happens. When I hold and press the top 2 for 3s (which is how we used to turn on/off the child lock), it displays what you see in the attached image, beeps, then returns to the default display.
Open the fresh food section. Is the fan operating there at the top rear? Can you hear it? Alslo look at the lower rear wall in the fresh food section. Is frost visible on that wall?Barry
The fan does seem to be on. When I open up the fridge, I hear normal fridge mechanical noise.
On the lower rear wall, frost is not visible.
Thanks. I'll give that a try probably tomorrow morning. If I do end up needing a new control board, any tips on where/how to acquire one?
Hi Barry. I got the cover off and there's lots of ice in behind (see photo attached). Might that be the problem?
Any suggestions at this point? Just let it defrost, then put it back together?
Also, my fridge doesn't really look like the one in the instructions, but I think I've been able to interpret properly anyway.
Ok. It's defrosted, and I've plugged everything back in. And, the fan is NOT going. Perhaps that has been the issue all along? Any suggestions?
Ok. I'm going to plug it in and see if the coils cool.
If they cool, but the fan is still not running or the heater not working, you still suggest I replace the board?
Thanks for your patience Barry.
Ok. I've turned it back on so will wait to see about the cooling. Yes, I have a volt metre. What should I test?
Sounds good. How do I verify if the heater is working or not?
The heater is not working. You can disconnect the heater and ohm the heater from end to end at the wire connections. A reading= good heater. No reading=bad heater.Thanks,Barry
EDIT: Hang on that may not be right. I am not seeing the heater.
Hi again. It has been on for a little over and hour, and the fan IS now running. But, it looks like a bit of ice is already starting to form on the coils... I'll wait to hear back from you on what and how I'm to test the heater (It's not quite clear to me what part is the heater).
See attached photos. There seems to be some tinfoil like aluminum behind the coils, but I can't really tell where wires connect to it.
The coils are icing up pretty quick.
The coils look good. They should frost like that with no cover in place. Adam was there a time that the door was left open for a while?
Put the cover back up and let it run a couple of hours. I have to head out again but I will try and check with the phone as I can. What do the errors look like after that amount of time?Thanks,Barry
Ok. I'm going to secure the cover back on now and give it some time.
Ya... the door was left open for about 5 mins while I was taking a look for the heater, but I think that's it.
Ok. The fridge part feels cool now, but the child lock is still stuck and pressing and holding the top two buttons results in the same error code.
Adam that is good news. I would replace the main control board. I would use the link below because they will accept returns on electrical parts minus the shipping. There is no test for what is happening but there are too many errors showing for it to be anything else.www.repairclinic.com/PartDetail/Main-Control-Board/DA4100128D/1515019?RCAID=1000064That is what I recommend doing.Thanks,Barry
One last question I hope Barry. Can you point me to instructions on how to replace the control board?
Adam if there are any special instructions such as programming those will come with the part. Make sure the refrigerator is unplugged before you start.
The board location is in the compressor area, usually to the right in a plastic or metal box. Be sure the refrigerator is unplugged before changing the board. If you swap the connectors from the old board to the new board one at a time that will keep you from getting same sized connections in the wrong place, if there are any. Most times not but it is best to be safe.
Hi Barry. Do I get at it from the back exterior of the fridge, or through the inside of the fridge?
Hi Barry. Me again. Just back at this now that I'm back at the cabin. And, I've replaced the computer, and the control panel is now working (so that's good!) in that I can change the temperature on the control panel.
But, the fridge is still not cooling. I've set the temperature to 40, but it's hovering around 48 and not getting any cooler.
Freezer is still just fine. What would you suggest now?
