This blower or drafter motor was outside the home. It was piped into the wall in between a bathroom and the utility. Nothing on the inside would give you any indication it was there…except there was a downdraft JennAir cooktop in the kitchen about 25’ into the home. The JennAir had its own motor under the stove. The motor in the picture did not come on when the JennAir was operating. I’m puzzled.
Once again, thanks in advance for your help.
