How to replace a fuse in string lights

Jen Sentani | Jan 13, 2025

Christmas was three weeks ago and you’ve probably already taken down your string lights for the season, BUT WAIT!  Before you do anything else, if you don’t know what’s hidden in this secret compartment, YOU NEED TO KNOW THIS!  🙂

A plug fuse compartment is opened to reveal two glass fuses, while two replacement fuses sit nearby.

This is Jen.  You might know me as CA Real Estate Group’s Client Services/Ops Director, aka Christine’s assistant.

Well, we have stringed lights in our patio and when my husband went to turn them on yesterday, he “blew a fuse” and “shorted something” (his words; not mine) and now our pretty, twinkling lights in our patio weren’t working…not even one bulb.  I was ready to order another set from Amazon but I thought I’d do some research on what exactly happened and if it can be corrected without paying for another set.

Not far into my research and I find this entry in ifixit.com:

Okay, so I found my answer.  If I replace the fuse, I should be able to get the whole strand working again!

Now how do you replace the fuse?

I found this wonderful YouTube video that taught me how to locate the fuse and how to replace it!  I was like, “Noooohhh…it can’t be THAT easy!  Can it?!?!”

I tried it just like the video taught me and with little to no faith at all, I plugged in the lights and THEY WORKED!!!  I am officially TODAY YEARS OLD when I learned about extra fuses in a fuse box on the plug of stringed lights!!!  I am beyond excited and needed to tell the world about this wonderful thing.

I hope this will help you to NOT throw away a perfect set of lights!  Happy New Year, all!
