There are several ways to fix faulty dusk to dawn light sensors, depending on why it’s not working.

How to Fix a Faulty Dusk to Dawn Light Sensor Simply reset the lights by turning them on and off. Thankfully, system issues concerning dusk to dawn lights are the easiest to fix. System issues commonly occur after power outages or minor problems in the light’s system, like incorrect wiring. Your dusk to dawn light sensor may not be working because of system issues or overrides. If your average reading is under or over 115 and 125 respectively, your dusk to dawn lights won’t work properly.įluctuating voltage is often caused by corroded or loose connections.įor your safety, call an electrician to help you with the best solution to this issue. Slight fluctuations in voltage are normal, but your home’s overall voltage should always read between 115 and 125 volts. If your dusk to dawn lights keep flickering on and off, or if the lights frequently burn out for no apparent reason, this could be a result of fluctuating voltage. Unkempt wires can cause a lot of damage to dusk to dawn light sensors as they cause abnormal arcs around the point of connection.įor this reason, they should always be checked and maintained regularly, especially if your area is more prone to rain, floods, and other natural calamities. Loose wiring can cause any light to misbehave, from fluorescent lights going on and off to no power at all. If your dusk to dawn light isn’t turning on despite your best efforts, it might be due to loose wiring rather than faulty sensors. Photocell sensors aren’t expensive and often come with long warranties, so they’re excellent investments in the long run. In such cases, the best way to fix a bad photocell is to simply replace it. They do go bad from time to time, though, especially if they aren’t connected to stable wiring. Photocell sensors have a lifespan of upwards of 10 years. If the lamp continues to exhibit odd behavior even after you’ve replaced the bulbs and removed obstructions, you most likely have a bad photocell. The only solution to bad bulbs is to replace them with new ones. Incandescent light bulbs, for example, burn out after about 1,000 hours of use. They might have also simply reached their expiration date. Light bulbs burn out or “die” for several reasons, including high voltage, recessed lighting, bad contacts, and loose connections. Naturally, the sensors won’t work if they’re connected to bad bulbs. Therefore, dusk to dawn lights should always be placed in an area with plenty of natural light. Sensors rely on environmental cues to work, after all.
If the sensors are obstructed by dirt, debris, or even shadows from trees, buildings, etc., they won’t work as they should. Like most sensor-powered equipment, the sensors on dusk to dawn lights may suddenly stop working as they should. Here we go! Reasons Why Your Dusk to Dawn Light Sensor Isn’t Working
In this article, I’ve listed all the possible reasons why your light sensors aren’t working, and how to get them back up and running. If you’ve ever asked the question, “why is my outdoor dusk to dawn light sensor not working?” or, “why is the dawn to dusk part of my light sensor not working?” you’re not alone.įaulty sensors are actually one of the most common problems of dusk to dawn lights. So if the lights don’t turn on and off like they’re meant to, we’re left wondering what exactly went wrong. Dusk to dawn lights have a simple yet ingenious mechanic: they turn on at sunset and turn off at sunrise.
