A solution to refrigerator defrost cycle not working,
causing frig to not cool properly (also for freezer not cooling and water
dispenser and ice maker not working).
Here are my observations and solutions after 6 weeks of problems
with my Samsung RS2533sw side by side refrigerator/freezer.
First problem was the refrigerator defrost cycle was not
working. I first called a local
technician to solve the problem. Big
mistake, he didn’t know what he was talking about and it cost $60 for
nothing. After calling around and not
finding anyone else who would service my refrigerator, I worked on it
myself. I finally diagnosed that the PCB
(or PBA) main computer board had gone bad.
All other refrigerator defrost parts tested ok with an ohm meter. Unplugging the refrigerator to ‘reset’ it for
any length of time did not solve the problem.
So I ordered a new PCB main from Searspartsdirect.com for $87 + SSH
(part number DA41-00134A or D or F – don’t worry about the last letter, they
are all the same part). The new part
solved the problem.
One note about ordering parts, I choose Searspartsdirect.com,
they were the second lowest price. They
also have very good customer service, at least when I’ve dealt with them. They will send a replacement part if the part
they sent you fails within 30 days (only once on electrical parts though). Partstore.com gets very bad reviews and for
just $6 less than Sears, I wouldn’t risk the agony of poor customer
service. Partselect.com is pricey, $150. Samsungparts.com was $20 more than
Sears. All these stores are online
because I could not find any stores that carry Samsung parts and it is even
harder to find a repairman willing to work on Samsung refrigerators, I live in Dallas
where there are 6 million people in the metro area and only 2 service men are
registered with Samsung as being qualified.
I found out something very interesting before installing the
new PCB main. In order to know if I
could do it myself, I took apart the back compartment and took out the existing
PCB main. I then reconnected it and put
it all back together so at least I’d have a working freezer. I then ordered the new part. In the mean time between getting the new part
and having disconnected the original main circuit board that interesting thing
happened. I came out a couple of days
later and found a pool of water on the floor in front of the frig. The original circuit board was activating the
defrost cycle in the refrigerator and had melted a huge block of ice, now water
on my floor!!! I had already ordered the
part and couldn’t cancel it, so I kept the part and installed it anyways,
rather than pay more postage just to get the cost of the part refunded.
So if you think you have a bad circuit board and unplugging
the frig to ‘reset’ it doesn’t work, you might just want to try disconnecting
all the leads to the circuit board and just stick it back together and see if
that actually ‘resets’ the unit. Just
the other day the freezer side completely shut down (freezer stopped cooling,
water dispenser and ice maker quit). I
disconnected the circuit board completely again (all 8 connections) and that
fixed it. Now everything works as it
should (note it may take several hours or even a day or two before everything
starts to work normally). One important note
before disconnecting the circuit board, UNPLUG THE REFRIGERATOR FIRST!!!
Another interesting thing I found out about the defrost
heater for the frig, is that during the defrost cycle it makes a soft, low
grumbling sound (I was trying to eliminate the heater as the cause of the
defrost not working). I know this
because while this sound was going on I disconnected the lead to the heat
element the sound immediately stopped and when I reconnected the heater plug,
the sound resumed. The heater plug is
next to the fan plug in the upper right of the compartment in the back of the
frig as you access it from inside the frig compartment.
Lastly to see if I can prevent having to disconnect the
circuit board all the time (we have infrequent power outages here which I think
have a lot to do with this issue), I bought a $10 surge protector just for the
refrigerator. Hope that solves that
problem and good luck to whoever has the same issues.
