What she means is that electricity is going to your pedal even though your foot is not engaging it fully "on". When you're sewing slowly, you're not sewing for 1/2 hr. without stopping. You sew, lift your foot off the pedal, adjust your fabric, stop to pin etc. Normally, your foot pedal should not be conducting current during these breaks and that's when they should be cooling down. Yours is continuing to conduct current as soon as it's plugged in the wall, so it seems. If you give the yahoo groups another chance it's an easy fix, I believe and they have photos and how to's. I've had to adjust several of my foot controls. More for speed than heat, though.
