Product review (4 stars): Good Dryer
We bought this dryer (Platinum/Stainless Steel color) DV520AGPwith the matching washer when my local store had it on sale, about half off Samsung list price.

The washer/dryer combo has been great.  They do a good job of washing and drying.  The dryer has left my close a bit damp but it's due to the cloths/sheets getting twisted and wrapped up, any dryer would do that and my old dryer did that.  The middle of the heap is still a bit damp.

My biggest complaint was that the dryer was making a loud buzzing noise while running after a couple months of owning it.  It seemed like every time it was heating it made the noise.  I called Samsung about it and was told that it was normal operation but it seemed to loud and too frequent.  After some discussions, it was agreed to send a repair person to look at it.

The repair man came and ordered a new gas valve and would come back 2 weeks later to install.  I received a call out of the blue from Samsung support to talk about my repair ticket and they told me the noise was normal operation behavior.  I went to the dryer and had them listen, they stated it was normal.  I asked about the repair call, they stated he shouldn't do any repair.  I asked how do I return the dryer because if it's this loud I don't want it.  They told me to work with my local store for that.  This made me quite upset that they are trying to tell me that this faulty unit was working as expected.

Regardless, the gas valve was shipped to me and the repair man came anyway.  Supposedly, once the repair person is called, it's out of Samsung's hands, thankfully!  He took 15min to replace the gas valve and the loud buzz went away.  He stated it was definitely a gas valve struggling to work properly.  He felt there will be a recall on gas valves soon from what he has been seeing.  Thankfully this happened within my year warranty.

So, if your gas dryer is buzzing really loud through out the cycle, it could be a bad gas valve.

Shame on Samsung for trying to pass this off as "normal operation".

Otherwise, I'm pretty happy with the product and would recommend people to buy, just watch for the bad gas valve.
