I'm embarrassed to say that I just NOW fixed my FE100's frozen augur. But smoke is billowing out and I'm ready to cook!
Thanks for all the help. I called and talked to Bill at customer service and he was very helpful. Once I got the motor off I couldn't make the augur budge so I used the advice to try water. Ran boiling water through the augur while tipping the FE back. Clamped on some vice grips and started reefing on the augur until it came loose. It took literally 30 minutes of tugging and twisting before the augur finally broke loose enough to be removed.
Once out, I reamed the augur sleeve with a paddle drill bit (a very long one) and a metal skewer. I then blew the sleeve out with my leaf blower, cleaned out the burner and box, reassembled the augur and motor, fired it up, dumped in some pellets and, BINGO, smoke.
Thanks to all. I'm a happy man.
