Ensure that the circuit breaker controlling the switch is not tripped and that the power is indeed reaching the switch. A simple way to verify this is by testing the switch with a non-contact voltage tester or by trying another device on the same circuit. Next, inspect the wiring. This is a critical step, especially in 3-way switch setups where wiring can be complex. Turn off the power at the breaker before you begin. Carefully remove the switch from the wall box and examine the connections. Look for loose wires, frayed insulation, or wires connected to the wrong terminals. Refer to the wiring diagram that came with your switch or a reliable online resource to ensure that the wires are connected correctly. If you find any loose connections, tighten them securely. If you're unsure about the wiring, it's always best to consult a qualified electrician. Once you've verified the wiring, assess the light bulb. As mentioned earlier, compatibility issues between the switch and the bulb can cause problems. Try using a different type of bulb, such as an incandescent or a different brand of LED, to see if the issue resolves. Adjust the sensor settings. Many motion sensor switches have adjustable settings for sensitivity, time delay, and operating mode. Consult the switch's manual to understand how these settings work and experiment with different configurations to find the optimal settings for your needs. For instance, increasing the sensitivity might help if the switch isn't detecting motion, while decreasing it can prevent false triggers. If the switch still isn't working correctly, try resetting it. Some Leviton switches have a reset button, while others can be reset by turning off the power at the breaker for a short period (e.g., 30 seconds) and then turning it back on. This can sometimes clear any internal errors or glitches. If none of these steps resolve the issue, the switch itself might be faulty. In this case, contacting Leviton's customer support or consulting with an electrician is advisable. Remember, safety is paramount when dealing with electrical work.
