    Hello

    Ok, glad I ordered 2 new motors, because after switching the bottom and top auger motor the stove ran great only for 2 days. Today when I started the stove, it went thru the startup cycle and lit the pile of pellets in the wear grate fine after the augers feed them properly. Then after going to the heat cycle, the top auger would not turn and the fire was dying fast. I wiggled the top auger and found that the snag was gone since I fixed the knit line so the only thing that stopped it from turning was the pellets dropping into the top auger chute. So it seems that neither auger has enough torque to reliably run this stove and they BOTH do indeed need to be changed out!

    New motors are due in Wednessday this week so we will see! Does this seem logical?

    Hello Again

    Well the top and the bottom MK motors quit at different times. Kicking them got them started again but to me they are just not reliable enough.

    So the brand new Multi-Product motors came in today. The bench test showed they were set to turn CCW like I asked. They were not silent but quiter. They may be good motors for the money but may not be the best motor for this job to be honest. See pics below

    Anyway, I put them in and they have been running the stove well ever since. I do have the stove on 1 - 1 and the lower buttons set to 3 - 9 - 1 for the lowest heat out put that the shed can handle. This low setting is probably a good test for the new motors. I just wished the stove had Auto On/Off, just need a way to lite the pellets even with some ash. I wonder if Mike tried having the ignitor higher up to be more aboe the ash? Oh, well.

    Just bought a Gleason-Avery off of a forum member....nice ball bearing top, huge stack. CW rotation (looking at output shaft side)......Can barely hear it run.

    I think you missed the boat on these Don, just to save $. They can easily be reversed on the rotation.....all screws holding things together.

    Hi Pete

    Thanks for showing the pics, they do not look very much different. If mine last 5-10 years that is still good and they are quieter than the old ones.

    If it was for my own stove, then I may have gone with the GAs but I was so turned off when the lady at GA said they had an agreement with ESW and would not guarentee they could be changed to CCWs !
