Can you tell me what jumping vac switch wires means?When you pulled the auger out, did a bunch of pellets come with it? When it quit, did it make the same bang noises, or just quit working? When you had auger out, did you make sure the set screw that holds the auger is not slipping? You can run the auger out of tube by jumping vac switch wires. That way you can check it and see. Just remember that auger is only running for a minute on initial start up. I would unplug igniter too so as not to waste it being on when testing as you will be hitting the reset button a few times to keep auger going. kap
