Question:

How do you change the fuse in a flourescent light?

I have replaced the bulbs and the light will not workHubby says fuse needs to be replaced but I dont know how to do itAnd he wont do it for me.always at work or too tired! Thanks for your help!!!

Answer:

Fluorescent lights do not contain fusesThey contain a device called a ballast, which is a black brick-shaped device with a number of wires coming out; these occasionally fail, and can be replaced: new ones cost $10 to $20, depending on typeBut a more plausible failure point is the starter, which is a small aluminum cylindrical can-shaped device, about an inch long and 3/4 inch in diameterNOTE: many fixtures do not use starters, as the necessary functionality is provided by the ballastBut if yours does, try replacing it: turn the device about 1/8 turn to the left, and it will come outIt will have a designation such as FS-4 on it; get a replacement with the same designationStarters are cheapIf replacing the starter does not work, or there isn't one, replace the ballast: remove the old one (cut the wires that go to the lamps about in the middle of each wire, and unscrew the wire nuts that secure the black and white wires to the power supply) and take it to the hardware store for a suitable replacementTo install the new one, you will need some wire nuts to connect the wires from the new ballast to the old lamp socket wires.
