Troubleshooting Led Christmas Light Strings

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

Troubleshooting led christmas light strings.

These lights are key. A faulty shunt may sound like a catastrophic failure but you can often fix it with the lightkeeper pro. 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.

Most brands of led christmas light incorporate a fuse in each strand. Fixing any broken circuit involves locating the break then repairing it. It can sometimes prove difficult to slide open the access door on a plug. Simply plug in the light strand and remove a bulb that s in or near the dark section.

If half the string is out look for the dead bulb closet to the end. The fuse is most often located behind an access door on the strand s plug. Two terminal wires should be visible. The next string which is plugged in after the problem string works normal.

If the entire string is out start with a bulb at the end of the string. By removing from socket. Led strings can fail when led leads corrode or wires break or fuses blow. If not you may have found your culpret.

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.
