DV337AER/XAA-0000 Samsung Dryer - Instructions

I originally called a repair person to come out but that was a total waste of time and money. He removed the front of the dryer claimed there was a dryer sheet causing the problem and put it back together.
Never again!
I watched a youtube video for step by step instructions on how to take the dryer apart.
I took the front door of the dryer off, removed the filter cover and the dryer drum & belt. Removing this was simple and allowed me to see everything I was working on. With the new part in hand, I removed one wire at a time from the non working heat sensor and connected it to the new part. That way I was sure I had the right connections.
I then removed the thermostat making sure to put the new one back in place exactly as the old one.
I then put the drum back in place with the belt securely fastened. I put the cover back on the lint filter and placed the dryer door back on securing it in place. The dryer is now working perfectly. It takes longer to take the dryer apart than to replace the old parts.

Samsung had no servicers available, after over 3 months calling and sending photos and signing papers they sent a refund. Never any advice on repair from Samssung. Saw a video by JEFF OSTIROFF that lfor disassembly and location of heating parts. Gor $40 Samsug service manual that was rather useless. Disassembled and tested thermostat, Thermistor, and heat element. Appeared that HI-HEAT thermistor was open circuit all others OK. Sent for new one, arrived damaged insufficientlyb packed Tested original again out of appliance, tested OK. Got replacement for damaged thermistor and put it in, reassembled and IT WORKED! Notvsure if original thermistor was intermittant, or connection problem was the fault.

Thank you
partselect.com for a much better heavy duty belt than the original. Way over priced, but well worth it. After watching the video & following it step-by-step, I now have a perfectly running dryer. P.S. don't forget to plug back in the (3) wire harnesses. The entire experience was a great feeling of accomplishment. Thanks again partselect.com

The design of my dryer is a bit different from the video on PartSelect - but it is very close. And if you watch the really good video on PartSelect plus a few others on Youtube you can figure out how Samsung in general designs the different components. You can fix this yourself definitely.

Cost of part to fix - about $50.
Repairman - didn't even ask. Would probably be $300-400.
Cost of replacement $1,000.

I rated the repair "A bit difficult" only because this is the first time I have ever repaired an appliance. If I were to repair this one again, I'd rate it as Easy.

I'm really thankful for the PartSelect video. This makes DIY repairs possible.

Thanks.

I would like to direct the attention to PartSelect instead of my repair. They were awesome in helping me to get my parts. I had called, a few minutes after the deadline for overnight shipping, the gentleman helping me, pushed the order through and I got my parts the next day, allowing me to repair my dryer. I have ordered several parts, for several different appliances, (all Samsung) and PartSelect has always come through for me. Excellent Customer Service!!
P.S. Don't buy Samsung appliances unless you want to get good at repairing them!

I removed the dryer top and saw that the belt was intact. (I had suspected the belt or something stuck in the exhaust fan or somewhere.) I watched a few youtube videos and took off the rest of the top plates and front door and inner structure that held the barrel. After i inspected and cleaned out the fan blades and exhaust areas, I looked at the pulley rollers (motor and idler rollers). The idler roller looked a little melted and chewed up. I replaced it with the new assembly. Also replaced the belt. Putting the barrel and new belt back on was harder for me than the videos indicated because the spring was very tight and the area to put my hands was small and didn't give me enough leverage. I eventually got someone to give me the third hand pulling the idling roller a little further over and the belt was back on. It didn't take me long to put the whole dryer back together. It is running fine now.

These are not instructions as much as warning that although it is a one-person job, the idler pulley assembly is not as easily manipulated with the barrel there. Doing the fix was straightforward: one screw holds it in place. The men in the videos seemed to have no problem with easily replacing the belt, but I needed help with the tight spring. Perhaps now that I've done it once, I could figure out how to reach around the barrel and yank the roller enough to replace the belt, but with the extra hand it took seconds and was super easy.

We unstacked our washer and dryer and needed dryer feet again.

Follow the video instructions.

Followed the video on the website and finished it in a short time. Now it works like a new dryer.

I still had to take it apart there was a small sock stuck in the fan that blowes the lent out my wife left the lent filter out one time. Your video was a great help. I'm a mechanic and it was easy thanks Anthony Ratto Tulipbike82@aol.com

Followed video and YouTube most was easy.... put the hooking up the belt took time

Took off the back of the dryer and replaced the thermistor. A $7 part that would have been a couple hundred dollars if we had to call a repairman.
