How to Fix a Non-Responsive Switch
If your switch is non-responsive, the first step is to test your switch with a good bulb. If the switch doesn't turn on the good bulb, the next step is to turn the breaker off. Remove the wires from the switch and connect the wires together, then turn the breaker on. If the equipment (such as a ceiling fan, lamp, etc.) is now working, the switch or its connection to the wires was bad.
