Company has previously helped, but this 3 month old stove is now dead and can't get my rep. Have replaced the room blower,bottom auger and have torn down and cleaned and checked all hoses, connections etc. several times. We have even reprogramed the control board which had it running really well until I had to shut it down to give it a good cleaning. Then it would light fine and run for an hour or so and go out with an E1. Then it would run only a few minutes at a time and E1. This morning I tore it back down and did the 'cleaning routine', put it back together and fired it back up. Ran great for 1/2 an hour and went into E1 and now the top auger stopped delivering pellets altogether. I tore it down and re-checked for dirty pipes, hoses,cracks,exhaust blower dirt, etc. The motor is fine. I switched the motor to the lower and it runs great. (put it back on the top). Ran diagnostics and still no top auger running. Any new suggestions that may help would be appreciated. Set up is basement with a 6 1/2' vertical run and then out 2', and the fresh air is the 3" pipe.
