Just changed the exhaust blower on j2000 and couldn't be happier! Jamestown wants well over 200 for the blower . I picked up a replacement from electric motor warehouse for 115 and I'm lovin it! It's quieter than the c frame that was in it and does a better job than the old one too. Anyone interested the motor number is hb-rbm120. I was told it wouldn't work ,and that I needed oem motor . Don't spend the big bucks cause it's not needed.
