This question is mostly directed at Mike Holton, but other opinions are appreciated. My Englander 25 PDVC has a build date of 6/2008. It is in it's 2nd season of burning, and has burned thru 6 tons so far, last year and this year. I thoroughly (behind impingement plate, etc) clean out the stove every Sunday, and give the pipe vent a sweeping after every ton. My question has nothing to do with the burn. I feel I have mastered getting the most heat from the stove at max efficiency and have no complaints about that. Lately it seems as if the room blower has 2 speeds. 1 and 2 are essentially the same speed. There is a huge difference switching from 2-3, but then going from 3 thru 9, the change in air volume is negligible. I recall a very distinct and noticeable change going from one room blower setting to another last year. Does this indicate a room blower problem, or a circuitry problem in the computer panel? Yes, the room blower has been cleaned.
