I have a pentair IC40 that is approximately 4 years old. My controller is a PC100. At the end of last season I started to notice on several occasions that all the lights on the IC40 were off. It did this off and on but it never stopped for too long. Now the IC40 doesn't appear to be working at all. The fuse appears to be ok and the connection is screwed up tight. When I turn on the system the lights will sometimes come on as it starts its initialization phase or the first part with all blinking lights. It will do that for approximately 3 seconds and then all lights go out. Once the lights go out I can jiggle the cable a little and sometimes it will do it again. Come on the initialization for 3 seconds then all lights off. Also at the end of last season I did the sequence to see how what % of the IC40 had been used and it showed to be 20%. Any help would be greatly appreciated.
