Question for the gurus,
Have a Liberty mounted on my truck, every once in a while if I have been sitting stationary with the lights going while loading or unloading the bar will lock itself solid but yet the controller panel will still be doing the indicator light dance.
Is there at heat sink inside the bar that would cause this?
When I pull the fuse for the bar it resets itself and goes back to normal.

Thanks
in Advance

Serial control? If not, it is likely a knock off bar as the LC bars do not use a special controller. Meaning the lights on the controller work completely independent of the light. Photos/model of controller might help too.

The lightbar is connected to a Cencom Sapphire controller. With WECAN that was added afterwards. It is a 54" Liberty, Date Of Manufacture 2012. Didn't have any issues this run with it. But it seems to only do it when I have been stationary for a hour or more and then goes Solid sometimes,not all the time.

Heat issue? Open it up and give it a going over. Over time thermal expansion can work ribbon connectors loose and cause issues with other electronics. Rule out the simple first.

to me... check all your connections and wiring since its added after he fact- second check your programming: was it programmed in the original software then reprogrammed in command?
rule out the obvious first.
after that it could be a heat issue or a I/O board with a occasional issue
to me with the fact that a power cycle to the bar fixes the issue im leaning towards a i/o board issue

Update,
Broke it all down and checked all connections and cleaned it up all. Just for sh!ts and giggles I dropped the fuses for the light bar power down from 20 Amps for 12V to 15Amp for 24V because of the 4 batteries in the truck and made a 6 day run requiring my lights to be on for 12+ hours a day with zero issues. So hopefully that is the end of that saga..
Thanks all for your input and suggestions. Reason #1 why I have been a member for all these years..
