I need to replace the relay on my 1137. How do I do this?

When you are finished, you should have three connections like this:

• The black wire from cord, a black wire from board, a blue wire from board.
  
• Other blue wire from board, a black wire from motor, a black wire from valve.
  
• The white wire from cord, other black wire from board, other black wire from motor, other black wire from valve.
  

Finally, all the green wires should come together under the screw of the “L” bracket.

Tip: The most common installation mistake involves bundling of the various wires in the wire nuts.
