I do not know why it does this once in a while. The stoker is now feeding faster. the ash on the ramp is down to 3 inches. The coal is not being blocked in the hopper as far as I can see.
It sounds to me like the t-stat is working and calling for heat but there might be a loose wire connection on the motor. If the motor has wire nuts on it I would unplug the stove and re-do the wire nut connections just to make sure they have a good connection.
