We have almost the same unit as Mr. Mark. For over a year I was having problems with the Valid system. The compressor would come on every 20 minutes. There were no leaks. I was going away for 10 days without the MH so I pulled the fuse for the levelers. When I returned I replaced the fuse and so far everything seems OK. Won't be using the unit for a few months so I won't pronounced it fixed just yet. It is quite common that when you have trouble with any computerized board to remove the power and it sometimes resets. Glad your problem was solved and it is good to hear that Monaco support is as good as ever.
