How do I replace the flourescent light box above kitchen sink?
When you buy a replacement light box it will come with instructions. Always make sure you have the breaker turned off so that you don’t get electricuted. Take the screws out of the old light box so that you can pull it away from the cabinets. Once the wires are exposed you may be able to untwist them or you may need to cut them depending on how they were connected to the house wires. Once you have disconnected the unit just connect the wires of the new box with the same color wires coming out of the wall. Put caps on the end of the wires that are connected and make sure you also cap the nonconnected wires. Then screw the light box back into the cabinets, turn the breaker on and then try the light switch once you have installed a bulb. Have you checked the breaker to make sure it isn’t flipped before trying to replace the unit?
