Richard, I also sent my control box to HWH and had very a satisfied dealing with them.  Back in about 2 weeks and $185.00.  It looked to me that they exchanged the boards out, because the relays were all white and when I got it back they were all black.  What ever they did it fixed the problem.  Mine was the front slide.  Sometimes it worked and sometimes it didn't.
