BULBS AND FUSES:
Fuses:
The fuses are designed to prevent a short circuit or overheating that could lead to damage to the lights.
The most common cause for a blown fuse is a power surge.
Each cord string of Christmas tree lights has a fuse housed in the plug. When a fuse blows, the lights
will simply stop working. Whenever an entire strand (or in some cases the entire tree) ceases to light,
check the fuses before you try tightening or replacing the light bulbs.
To Replace a Fuse:
1. Unplug the Christmas lights.
*****
Make sure the light string is unplugged from the wall and any other light strings
before you start working on it.
2. Slid open the fuse box on your Christmas tree light string to confirm that the fuse is
blown. You can see the fuse box clearly marked on the light string plug. Slide the
top of the fuse box off with pressure from your thumb. If you cannot move it with
your thumb, use a flat-head screwdriver to gently push the door open.
3. Examine the fuse to see if it is blown. A blown fuse will have a black residue
evident inside the glass chamber. If there is no black residue, the blown fuse is in
a different string.
4. Pop out the fuse by gently placing a small flat-head screwdriver under the fuse and
apply gentle pressure upwards.
5. Place the new fuse over the area where it will be installed. Press down gently over
top of both contact areas with two fingers until the fuse pops into place. *****Do not
apply pressure to the glass part of the fuse when removing it or putting the new
one in. Apply all pressure to the metal contacts. Complete by sliding close the
fuse door.
