Step 1: Check the Breaker Box Fuse
If your ceiling fan is not running, check the fuse at the breaker box to determine if it has blown. Replace it if necessary. Otherwise, turn off the power to the room where the ceiling fan is located.
Step 2: Use the Voltage Meter
Unscrew the switch plate and remove it from the wall. Then, clip your voltage meter to the screws on either side of the switch. The meter will tell you if the screws are holding a charge or not, something you need to know before you pull out the switch housing to avoid getting shocked.
