How do I replace the electronics box?
The electronics box can be removed in two steps. First, unscrew the screw on the bottom of the box. The box can now be separated from the control box. There are two connectors inside the electronics box that need to be disconnected. Pull the two connectors towards the screw. Once these are disconnected, the electronics box can be shipped back for a replacement.
