DV42H5000GW (A3-0003) Samsung Dryer - Instructions

YouTube, YouTube, YouTube. I YouTubed many videos on how to take a dryer apart to reach the drum support roller and axle. After watching numerous videos, I settled on one that had my exact model of dryer. For my dryer, previous inputs said I needed two rollers to for my model. That is not the case. My model actually has 4 rollers, 2 in the front and two in the back. I ordered 2 initially but only needed 1 thankfully since only one roller was bad. Keep it simple stupid is how I got it done. Dryer's are pretty simple machines mechanically. Don't trash your noisy dryer. We bought ours in 2014 and it only recently started giving us issues. This is after 2 moves and being run daily for a family of 6. I'm glad I found partselect.com. They saved me a ton of money.

Watched a video on utube, how to repair my 16 month old steam dryer. The hardest part was laying on my belly holding the spring loaded tensioner and slipping the belt on around the blower housing. Only cost me $23. Winning!

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.

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

Reassembled

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.

This was a troubling exercise. Took apart the dryer covers and removed the drum. Removed the igniter and it had a crack through it. Checked with multimeter for continuity, and there was none. Took a picture of the original installation and sent away for part. Just mount and plug in….reassembled and works fine.

I removed the dryer vent and cover to take a look at the inside of unit. Then I saw that wheel on the pulley was damaged and belt was tangled up. I simply replaced the pulley and placed the belt back. Samsung advised that I replace the unit, but myself $800+ on a new unit.

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

I had to take the whole thing apart to replace the drum wrapper. I followed this very helpful YouTube video for the step-by-step instructions on disassembly.

Once the new drum was installed, I followed the steps in reverse to put everything back together.

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.

removed the top cover, remove control panel,remove door, remove belt assy, and pull out old drum and installed new drum. Used only a phillips screw driver and took approx. 30 min. Dryer is quit and drying better.
