DV431AGP/XAA Samsung Dryer - Instructions

I YouTube it and there’s a step by step process on how to do it, took maybe 30 mins. If I can so can you

Dryer would not start but electronics were working.

Pulled top of dryer off; noticed the belt was loose but not broken.
Went in through the back (1 screw and removed the exhaust pipe/plate); noticed the wheel was broken and thus the belt had fallen off.

Ordered replacement wheel/arm.
One screw to remove old one, one screw to install new one...tentioned the belt. Dryer was good as new.

Cleaned the sensors from inside the drum with alcohol and that did not work. Ordered two sensors. Lift top cover. Remove screws on each of the front side that secures front cover. Unplug door sensor and pull front cover towards you and lift at same time removing from frame. I own dogs and immediately noticed dog hair and surprisingly lint all over the place. Remove the screws from the lint trap. (Theres one you access from inside the drum.) Unplug your sensor wires. Remove lint trap. The sensors simply push in/out. While I was in there I removed the cover for the lint tube and cleaned it out good. Lint had started to gather around the fan. Reverse your process and your done. TIP: Keep your screws orderly as you unscrew them. If you have this problem, just a good cleaning of hair, lint, dirt may do the trick as it essentially packs around the plug of the sensors. I had already ordered my sensors so I just put them in. I took my time and cleaned good and it was about an hour. It could be done in 15-30 minutes easily.

I ordered twice from this site. the thermistor was the first order, the fuse was the second order. Turns out the thermistor sent was the WRONG one. When I reassemble the dryer, after 20 minutes the thermistor sent burned up to a crispy chard. The ohms on the wrong part was 12ohms. per the dryer diagnostics the thermistor should have been =<1 ohm. I put in the original part and it worked. The fuse did the trick. the thermistor, not so much. Lesson to be learned is to not rely on this sites parts compatibility information. Look at the specs for your dryer from the manufacturer.

Just popped it in the dryer trap opening

Separated the outer door from inner door, removed glass globe. Replaced the seal

Reassembled

*** Unplug Dryer ***
Spent years (PITA) trying to figure out how to do this repair.

About 2 weeks ago I came across this U-Tube video.
This video really saved the day and I cannot tell you how much I appreciate this guys video.

Here is the link to an awesome video.

Tip: It may help some of you to bring up this video on your phone or laptop to reference as you do the repair.

Good luck

After viewing many instructions on how to replace a broken drum drive belt on UTUBE and the video you sent me the project was completed with no problems and with ease.

However, I did discover large amounts of lint caked to the bottom of the lint screen housing just beyond the filter screen. There was minimal lint on the lint exhaust fan blades and no lint in the exhaust ducts.

I didn't recall seeing any video instructions drawing attention to potential lint issues, it just made good sense to clean the entire system while it was apart . At first I saw no major lint problem.

However, after removing the lint screen and placing a vacuum cleaner wand to the bottom of the lint screen housing (the bottom is not easy to see) my vacuum cleaner hose became clogged three times. I realized there was a major lint issue isolated to this area.

Many of the on line complaints focused on parts not properly fitting their dryer. they had to modify the parts in some way to fit or operate or they had to return them for other parts. Just think of the time wasted and the lack of use of their dryer.

I called and talked to a tech. Gave them my model number and the tech located the correct OEM parts for my dryer. I paid the extra money for OEM parts because I wanted my dryer fixed and restored to service in the least amount of time.

Outside the discovery of the not so obvious lint issue, the repair project was easy and the dryer was restored to full service with minimal down time.

Thanks for all your help and fast delivery service.

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.

Threw old one out, opened box, put new one in slot.

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 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.

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

Follow the video instructions.
