The first thing you need to do is to check whether the light switch is receiving power. If there is no voltage present, then the light switch is not receiving power and you will need to check the. When a light refuses to turn on, or a switch feels “dead,” it's easy to jump to conclusions and assume the bulb is faulty or the wiring is irrevocably damaged. Since household wiring uses alternating current (AC), you'll set your multimeter to the AC voltage range (often denoted by V~ or VAC). Many people automatically shy away from electrical work and it can be dangerous, so it's worth hiring a professional electrician to do this for you. Scratches, cracks, or chipped surfaces can indicate trouble. Check the switch's housing and. Are you facing a flickering light or a switch that's not doing its thing anymore?
