Troubleshooting Led Christmas Light Strings

Then a whole string or perhaps a half string circuit would go out.

Troubleshooting led christmas light strings. If the entire string is out start with a bulb at the end of the string. Led strings can fail when led leads corrode or wires break or fuses blow. These lights are key. Look for the lights that have a splash of red on the bulb near the bottom.

Each string has a control to change the color sequence which works normally. The fuse is most often located behind an access door on the strand s plug. The next string which is plugged in after the problem string works normal. Two terminal wires should be visible.

I have a string of led christmas lights with a problem about 1 2 of the lights are on but very dim the other second half is on normal. If not you may have found your culpret. Plug the string of christmas lights into the wall socket. By removing from socket.

Most brands of led christmas light incorporate a fuse in each strand. To replace the fuse you must slide the access door open pop out the tiny fuse and replace with a new one. Fixing any broken circuit involves locating the break then repairing it. A faulty shunt may sound like a catastrophic failure but you can often fix it with the lightkeeper pro.

I fixed mine by taking a copper wire about 1 5 cm 5 8 long and inserting it into the hole alongside the broken terminal wire.
