CFS Failure

One of my CFS units seems to have $#!T the bed. When I put a filament in, the LED comes on, but the motors won’t move. Doesn’t matter which slot. Also, if that unit is in line with the other CFS units, the printer will start printing, then go dark with an error about over current. Support said to check all the connections, but that didn’t help. Anyone else have a similar issue?
