This is a 4 wire system and the first thing I thought of was to separate the neutral from ground in the dryer. So we took the ground off the neytral and used a lug to bond the the dryer. Still wouldnt hold. The same problem on a slide in range?Is this a 3 wire or 4 wire unit? Is the Neutral and ground separated in the dryer and range. Many of the dryers and ranges come shipped with the neutral and ground tied together with a strap.
