DIAGNOSIS This is a power supply issue. Either the outlet is faulty, the cord is not fully seated, or the internal thermal fuse has blown from a previous overheating event.
FIX Follow the power chain in this order:
1. Confirm the outlet works by plugging in another device.
2. Check that the power cord is firmly plugged into both the wall AND the port on the back right side of the K-Mini. It can look connected but be slightly out.
3. Try a different outlet on a different circuit. If the blue light comes on, the first outlet/circuit was the problem.
IF THAT DIDN'T WORK If it's still dead on a known-good outlet, the internal thermal fuse may have tripped. Unplug the machine and let it sit for at least 2 hours to cool completely. This can sometimes reset it. Plug it back in.
HEADS UP Do not attempt to open the case. If the thermal fuse has blown permanently, it's a safety feature indicating a serious internal fault. The machine is not user-repairable and needs replacement.
