Repair or replace?

ReplaceSwapping in another CompactLogix 5370 L3 controller is the fastest fix when the 1769-L38ERM will not boot, shows a solid red fault LED or has lost its project: download the program, match the firmware revision and the line is running again. A replacement 1769-L38ERM is sourced on request, so weigh the sourcing lead time against a repair turnaround.
RepairRepair the 1769-L38ERM when the fault is in the power section, a port or the status display rather than the processor core, or when the controller carries a firmware revision or validated project you cannot easily re-flash onto a different unit. If a replacement is already installed, repairing the failed 1769-L38ERM gives you a tested spare on the shelf for the next failure. Every 1769-L38ERM repair is fully function-tested and covered by a 1-year warranty.
