If your Christmas lights don't work, you may have a fire hazard.Replacing a Christmas light fuse involves locating the fuses, removing the burnt one, and installing the replacement set that came with your Christmas lights.If the problem continues, you may have problems with your light strand.
Step 1: Plug your Christmas lights back in.
Make sure the lights are off before you open the plug cover.It's a good idea to take out the electrical before you work on it.It's a good idea to be careful not to harm yourself.The wall has a sockets in it.Pull the sockets out of the wall with a firm hold.Don't remove the sockets from the cord.Light sockets can be removed from the cord.Test your lights to make sure they are still working.If the lights light up, turn on the switch.
Step 2: The male sockets can be found.
Male sockets have more space to receive plugs than female sockets.They are plugged into other light strands or into the wall.If it's male or female, check the sockets.There are only male sockets for Christmas tree lights.All the light strands are not working.If multiple strands are not working, you may have to replace them.Don't forget to look for male sockets that are malfunctioning.The entire light strand won't work if the fuse is not working.
Step 3: Make sure the sockets are marked and configured correctly.
There is an arrow pointing away from the cord in marked sockets.There is a marked section of the sockets.The fuses are located on the underside of the plug.The sockets have pointing arrows on them.They should be pointing towards the male end of the plug.There is a sliding door that hides the fuses.The piece marked with the arrow slides up to reveal something underneath.
Step 4: The door to the sockets needs to be opened.
The arrow and sliding door are needed to open the sockets.If you can't move the door by hand, you may need a small screwdriver.There are grooves on the door.You may be able to push this door up with your fingernails.If it does not come up quickly, don't force it.You may need a small flathead screwdriver or kitchen knife if the door won't come up by hand.The small size of the door makes finding a knife or screwdriver difficult.The knife or screwdriver can be used to push up the door.You don't want to damage the sockets or the fuses if you use too much pressure.
Step 5: After you open the door, check the fuse.
You can see the fuses underneath when the door is open.If the fuses are damaged, it's time to replace them.Make sure you don't lose them, they are very small.The fuses are located.There is a chance that there will be two, but only one.They should be behind the door.You need to make sure the door is not too far away from the fuses.The fuse needs to be removed.The small screwdriver can be used to open the fuses.It should be easy to remove them.Don't use too much force to not damage the fuses.Don't lose the fuses.The small fuses are difficult to misplace.
Step 6: To find out if the fuse is burnt, look at the color of it.
It is easy to recognize burnt fuses.Before you decide if you need replacement fuses, look at them carefully.You can use a voltmeter to check their strength if you are not sure.The burnt fuse was dark.The fuse will no longer work if it is dark to the eye.If you can't tell immediately, look more closely.External signs do not show the burnt fuses.To check the strength of the fuse, use a voltmeter.If thevoltmeter doesn't register anything when checking the fuse, then it is burnt and needs to be replaced.
Step 7: You need to find the replacement fuses that came with your lights.
You might have saved any replacement fuses.You may have to look for an electronics store that has spare fuses.You need to locate the spare part.There are small plastic bags taped to the light set that hold the spare fuses.If you removed the spare fuses from the plastic bags, remember where you put them.They should be kept in a secure location with Christmas lights.Find a store that sells electronics.You might need to go to an electronics store to find the fuses.It may be difficult to find them at those who don't do Christmas lights or electrical repairs.
Step 8: The fuses need to be replaced.
Put the spare fuses back in the plug door after locating them.It's important to not damage them when you put them in.If you're not careful, they can be easy to break.The fuse should be put into the sockets.Don't force them in.They should be in place.Before closing the plug door, make sure the two fuses are secure.They should be in the grooves.The plug door needs to be closed.To cover the back up, use a small flathead screwdriver or kitchen knife.
Step 9: The lights need to be plugged back into the outlet.
If the Christmas lights work, you should replace the fuses.There could be another issue if the lights don't work.Make sure the door is closed.You don't want it to fall out of place.The lights need to be plugged back in.Your Christmas lights should light up.If your lights don't light up, that's not the problem.Make sure your sockets are in good shape and check your cords for any damage.
