I just posted about how I can't get my old auger motor off so that I can replace it.  While I was waiting to see if someone would reply, I plugged in (but did not attach) my new auger motor to see if having a new motor would clear up the "auger jam" message.  It didn't.  The new motor turns, but after about a minute, the "auger jam" message reappears.  I've cleaned the optical sensor with alcohol and a Q-tip.  I also bypassed the vacuum chamber by stringing a copper wire between the two electrical wires (after detaching them).   Any other ideas out there?
