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?
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.
