I have a Samsung DV350AG gas dryer.

The control panel lights up, the door switch works, I press start, the panel indicates it's about to go, then nothing happens.

Based on threads I read here (thanks all!) I checked the belt - it's fine. I checked the vent for lint clogs or kinks - it's fine. I took it all apart and replaced the thermal fuse, thermistor, and hi temp thermostat.

It then seemed fixed (yay!) and ran for a few days, and then stopped again with the same symptoms (doh!).

While I had it taken apart I cleaned it out as much as I could, but it didn't seem particularly dirty.

My dryer vents directly out a window that's behind it so I know there's nothing obstructing the vent line.

Any ideas?
