Hello pellet burner friends, I own a withfield pellet stove and the last year or so my exhaust draft has been slowly decreasing. Checked all usual suspects but all is ok (air intake pipe clean, exhaust pipe clean, door gasket is tight, stove is clean from ashes,exaust blower inside casing is clean). So i am left with 2 options, trying to change the exhaust motor or the control board. I checked the output voltage of the control board (you can do so with a multimeter from the front bottom of the control board, see here : ) http://www.woodheatstoves.com/zcart/images/16052112.jpg All i got was 50 volts on all three electric components (auger, room and exhaust motors). Is 50 volts normal or my board is slowly fading away ... thanks in advance for your replies. Marion.
