WGD9600TW1 DRYER HUMS-WON'T START--did diagnostics
Hi. I'm very much an amateur but the dryer is all taken apart now, so there's no going back!
When Start is pressed, you hear a hum and drum doesn't turn, and the dryer doesn't go on. So I suspected the motor. At first I swear I saw a PF code briefly. Some people online say the thermistor can cause that error code although I'm not sure why that would be.
When I went to diagnostic mode it said F01, which means control board apparently. I did the diagnostics per the tech sheet.
The power to the motor on the control board was ok.
The thermal fuse was ok.
The thermistor had a reading of 16 ohms with a room temp of about 69, which according to the chart I saw means it's bad. It should be 10. It should be 16 at 60 degrees.
Per the tech sheet I checked the resistance on the motor and I got a reading of 0 on all three tests: main winding, start winding, and belt switch. Tech sheet says the readings should be somewhere between 3.3-3.6 (main), 2.7-3.0 (start), and from infinity to a few ohms as the pulley arm closes the switch. But I get zero on all 3. Am I doing them wrong? Some sites say the motor should be zero.

Ohming the motor would help much if it is hummmmming but not running.
Nothing caught in the fan blower wheel, drum supports are not seized....if all are ok = new motor time.

I changed out the motor and it works but only work light loads. With medium loads the drum won't turn. Iwatch it turn with light load and there's nothing obvious to me, no noises, nothing loose. The belt seems tight but I'm guessing it could be the belt . Or maybe the rollers are rubbing somewhere?

What happens instead?....exactly?
With medium loads the drum won't turn.
With a new one, used one?

New motor. With medium loads it sort of hums but not like before, when the motor was bad. Low pitched. With light loads drum turns and as you add more and more eventually it stops.

Definetly worth making sure none of the wheels or idler pulley are stiff to turn and free wheeling.
Make sure the washer is spinning correctly and clothes are not overly wet.
More sounds like a possible bad motor to me
