Sounds like the compressor relay's contacts are welded together.

If I am out to lunch on this one could you explain what the function of this relay is Thanks in advance denman Yes upon further examination it is a switch (solid state) . This switch is between L2 and the overload. What purpose it serves is another question as it is not between any compressor windings.
