Samsung Dryer Spins Too Fast

[pumper]

Bought this three year old gas steam dryer on FB for $50, said it didn't heat. Wanted to tinker so I bought it and tested/replaced the gas valve coils and belt. Heats like a champ now but drum turns too fast. Clothes come out horribly wrinkled. So I fired up the parts cannon:

1. OEM main control board. Didn't fix it.
2. OEM motor (came with blower, mounting bracket/clamps, idler pulley & spring). Didn't fix it.
3. OEM wiring harness. Didn't fix it.

These OEM parts were sold as "open box" but what are the chances I would get a part with the same problem? Lol

The video doesn't really do it justice. Wet clothes barely drop at all, mostly from the two to four o'clock position. I think clothes should drop no later than the 12 o'clock position for proper drying. There's not much about this on the web, mostly dealing with a cracked motor pulley which would allow the belt to ride on the motor shaft instead. This part looked good on mine but I replaced it anyway. It didn't help.

I have three other dryers and none have this issue. A few years back I bought a used LG dryer that did the same thing, and I ended up just getting rid of it a few months later.

I put the old belt back on and retested, with the same results.

About the only things left to replace are the boards for the dial and display, but I don't know why those would cause this. Any ideas?

Drum RPM is a function of mechanics such as drum diameter in relation to motor design RPM & motor pulley diameter. Changing the control board and wiring harness won’t have an effect. Motor RPM on dryers isn’t variable by the board.

That speed is totally normal.
Only thing that would affect the speed is a wrong motor, wrong pulleys or wrong belt.

The chances that any of that stuff would fit anyway is pretty slim.

There are dryers with variable speed motors over here in the EU.
But I don't know of any model besides the F&P SmartLoad that was sold in the US in the past 30 years that had one.

SmartLoad, the US models, are variable speed only regards to slowing during home position search for opening the drum door. Normal tumble, both forward & reverse, is at a fixed speed.

Since you mentioned you had a LG dryer that did the same thing is why I avoid those dryers like the plague, only ‘good’ dryers that are available at this time are the Whirlpool 29” top filter dryers in both gas and electric, there’s a reason why they are still being made along with being popular.

My Frigidaire dryer does the same thing. It just needs to slow down a tiny bit. I still have the GE hooked up out in my shop for bigger items. The GE dries perfectly almost every time.

I believe they're Korean dryer characteristics.

Samsung dryer tumbles too fast

Take a look at the motor, pulley, and see if it’s a standard screw on pulley you might be able to find a slightly smaller one. You can also take the pulley to a machinist and slightly reduce the size of it to reduce the tumble speed.

I have little use for Samsung and LG dryers that’s for sure,

I own a LG dryer

I own a LG dryer, and it tumbles correctly. I've owned it since 2017 with no issues. It turns out beautiful wrinkle free clothes. I think somebody has altered it in some way.

Sean, I agree with this completely. Even when it comes time for me to get a new washer, I'll likely keep my old Whirlpool 29-inch dryer because there is nothing whatsoever wrong with it. And when it dies, I'll get another WP 29-incher if they are still being made even if I have an FL washer from another brand. I don't care a bit about matching machines because my laundry is in a closet, the doors are always closed, and no one sees them anyway unless they are being used.

Only thing is 29-inch WP dryers max out at 7-cu ft so would it be able to keep up with the larger volume of laundry produced by high-capacity modern washers? I'm thinking probably so, because modern dryers are mostly around 7.4-cu ft so not much of a difference there really.

Yeah, My LG Dryer does the same thing, unless it is fully loaded. It also requires quite a full load for the moisture sensor to work properly. I'm sure it is an engineering and design issue and not really repairable.

 

[DADoES]

 
Tilt the dryer slightly off-level toward the sensor bars so smaller loads have consistent contact while tumbling.

I don't have a problem at all with my LG dryer. Sensor is accurate even on smaller loads. Maybe the installer adjusteed it to pitch slightly forward.
