When a fluorescent light fixture stops working properly—either failing to start or flickering—it’s usually due to one of two problems. In most cases it’s either a worn-out tube or bulb, or a faulty connection at the socket. In both cases, you should be able to make the fix yourself. However, if you’re not comfortable working with light fixtures or don’t know how to shut off your electricity, then you should probably hire a professional to help you with this.


Before you do anything, turn off the power to the room. Then, check the lighting tube and the socket. If the tube is discolored, usually with blackened areas at the ends, then this generally means that it’s broken and needs to be replaced. If this is the case, your job is easy. Simply unscrew the old one and replace it with a new one.

If you don’t find any signs of discoloration on the tube or if the problem is a flickering light, check the socket connection. In humid climates, it’s not uncommon for the contact elements to get oxidized, in which case you’ll want to clean them with a cotton swab and a contact cleaner. Don’t use any abrasives, as these can ruin the protective coating.
