Troubleshooting Led Christmas Light Strings

The fuse is most often located behind an access door on the strand s plug.

Troubleshooting led christmas light strings.

Two terminal wires should be visible. If half the string is out look for the dead bulb closet to the end. 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 the entire string is out start with a bulb at the end of the string.

Then a whole string or perhaps a half string circuit would go out. It can sometimes prove difficult to slide open the access door on a plug. A faulty shunt may sound like a catastrophic failure but you can often fix it with the lightkeeper pro. Each string has a control to change the color sequence which works normally.

To replace the fuse you must slide the access door open pop out the tiny fuse and replace with a new one. These lights are key. The next string which is plugged in after the problem string works normal. Led strings can fail when led leads corrode or wires break or fuses blow.

By removing from socket. Look for the lights that have a splash of red on the bulb near the bottom. If not you may have found your culpret. 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.

Simply plug in the light strand and remove a bulb that s in or near the dark section.
