Chosen Solution
We were getting the e5 error on our samsung french door fridge freezer. Following the advice of many posts on the internet, I checked the defrost temp sensor and found the plug to be very corroded. I purchased a replacement but when going to install it I have noticed that the corrosion problem as eaten away one of the pins in the socket. The socket (looking at the lugs on it) does not come off into the fridge unit, it must be removed after removing the whole back of the unit. Has anyone done this repair? I have not so far been able to find a part number for that socket yet. Edit:
Added photo. This is the socket. You can see the top right receptacle has no metal pin in it. You can also see that the retaining clips are this side of the fridge wall, and the yellow body is larger than the hole, so it does not ‘come out this way’ and needs to be accessed from the back…
Just as a bit of closure on this. I dug out the receipt from when we purchased it, which was 5 1/2 years ago. Contacted Samsung with the description, photos, report of “unrepairable” from their approved technician. About 1 week later they got back to me with the information that “due to a major manufacturing defect” they would offer me a refund of the full purchase price (in store credit at the same retailer, unit to be returned). Unhappy as I am to lose my sodastream fridge, I don’t think I could have hoped for a much better outcome after more than 5 years.
