feeding problem

PostBy: tozz On: Sun Nov 25, 2012 5:48 pm

LL Pioneer stove, Coaltrol thermostat, power vent, barometric damper, and manometer which reads .04
Thermostat is set at 11 min and 90 max and I still have 3 1/2 of ash at the end of the shute with a feed rate of 99. Its been feeding at 99 constantly in an effort to reach the temp set point of 75*. I have been gradually bumping up the max rate over a day and a half. I've never have this problem before. My last years setting was 9 min 50 max which at 99 feed would give me one inch of ash at the end of shute. Could the termostat be bad?
Thank you
Paul

My bet would be something mechanical. Check moving parts being rusted and stuck, feed arm bearing bad back edge of carpet/pusher plate bent out. If you plug the feed motor directly to outlet does it push the fire over the edge?
Another scenario could be fines blocking the front holes in the grate giving the impression of not feeding enough, this would show up as a lot of unburnt coal in the ash pan and a pathetic flame.
See tips and tricks in Leisure Line section. Shows how to remove grate.

Thanks Flyer5 for the prompt reply.
1. no unburnt coal going into the ash bin
2. plugged feed motor direct, no hot coals going into the ash bin

I'm going to shut it down and in the morning I'll remove the grate and see what it looks like. I'LL keep you posted.
Thanks again

Try to empty the hopper before pulling the grate. Start with an empty ash pan and pull whats left into it. Remove the hopper and look at the mechanics back there as well. Another thing you can check without pulling anything apart is make sure the gear motor is tight in its mounting and not moving around. Dave

I noticed that one bolt that holds the gear motor is almost out and the motor moves. Can I just remove the gear motor housing and retighten the gear motor bolt? Could this be the problem?
Thanks

Yes it can be. Just make sure to install the same way it came out. The output shaft and the 2 5/16 bolts should be closest toward the stove. The cord when looking from the rear would be on the left. If the motor was taken out for any reason in the past it could be bass akwards .

Thank you Flyer5, it was the loose feed motor that was causing the problem. I'm good to go now.

Thanks again
