I have model number NX58J5600SG and several of the knobs have just fallen off the stove due to the cheap plastic insert breaking. I contacted customer support and was told I should purchase new knobs from the parts store for $79.32 each. This is absurd! They break due to a manufacturer defect, not abuse or wear. I would be interested in joining a class action lawsuit as well.
FYI - Having the same problem as others have reported - the center female receiver (the plastic" part) has cracked badly on several of the knobs. Stove/Oven is a NX58F5700WS, purchased ~4 years ago.
Ordered OEM replacements on Amazon which aren't perfect, but are better than the broken parts which are a safety risk IMHO.
Just got home and found out that 4 of the 5 knobs on my range are broken! I'm an engineer, and I understand maybe making the knobs weaker than the range connections, but ONLY to the extent that the expected value of the replacement costs for the knobs are cheaper than the corresponding costs of fixing the range, and I don't buy that this is the case here. Somehow, I've managed to go 43 years without ONCE breaking a knob, and this, the most expensive range I've ever bought, breaks 4 knobs after 3 years???
Samsung: make this right or say goodbye to me as a customer. I know someone who just bought the same range, messaging them after this to see if they can return theirs.
Samsung won't stand behind any defects even if there dangerous. They will tell you where you can pay to fix them . Never buy another Samsung product
If someone does a class action lawsuit, I'm definitely in. We need to look and see how to get one started. To charge $90 for replacement knob DG64-00473B is ridiclous. All of mine were totally fine until the last month, when all 4 broke and the only thing broke is that cheap plastic part.
After just a few years of use all but 2 of the knobs on my Samsung range have broken. And the two left are hanging on for dear life.
I have read pages and pages of complaints about this issue without any real response from Samsung. Just adding my experience to the pile with the hope that Samsung will at some point realize that they want to help their customers out and stand by their products.
In the meantime, I am sending this thread and the others like it to Consumer Reports.
Knobs are junk. 4 of 5 have already cracked/broken. Used a small zip tie which seems to work well. Figured since the knobs are plastic, I guess a plastic zip tie will suffice.
