Similar situation as a few others. But basically it turns off within a few minutes after starting. It definitely warms up, I don't smell any burning. We put in a "normal" load, and that's where it would stop. I turn it back on, and the "check filter" light blinks. So now we've halved the load and it seems to work. Could be moisture sensor. But when I tried to replace it, just can't seem to get the lint trap off. When I looked behind the dryer and took the vent tubing off, the lint that was trapped in there felt wet. But the tubing (the accordion type), was not clogged. Not even sure where to start. Please help me troubleshoot and diagnose. Willing to try anything. This happened a few months ago, and it started happening again this weekend.
