@ssd2495 start the trouble shooting with the help of the diagnostics program of your dryer. Use the techsheet HE3 Techsheet to activate the diagnostics test mode and see what you come up with. Right now there is a plethora of possibilities of what could be going on.

I had this problem with an Amana dryer. Opened it up yesterday and found several socks in the bottom of the dryer under the tub, including one wrapped around the drive motor. Carefully unwrapped the sock from the drive motor, cleared out the other socks, lint, and dryer sheets that had accumulated in the base. Reassembled and the dryer is working properly once again.
