How do you check if a photocell is working
Control inside this photocell is a sensor that detects the amount of light that is out it is important to note that a photocell sensor is sensitive to all light not just sunlight. First let's find out
How do you test for a bad photocell
In order to find out whether or not the fault lies with the pair of photocells, the first check is to simply wave your hand in front of the photocell and listen; if you hear a click, the photocell is working; otherwise it is faulty.
How long should a photocell last
A: If your light burns continuously, then the photocell has gone bad, and the entire unit should be replaced. The life span depends on how often and long it is turned on, but mine usually will last upwards of 10 years, or more.
What causes photocell failure
One common problem that affects photocell functioning is incorrect or loose wiring between the photocell and the main circuitry of the lighting system. The wire that connects the photocell to the lighting circuit needs to have a solid, soldered connection. In addition, the system needs to have proper electrical power.

How do I know if my photo sensor is bad
There's No Light
While the beam between the photo sensors is invisible, each sensor should have a small LED light on the side that you can see. This lets you know that each sensor is on and working. If the light of either sensor is off, then that sensor has either become disconnected, or it's broken.
Why is my dusk to dawn light bulb not working
If your light bulb is not going on or off as expected
After you have determined the bulb is working remove the tape and clean off the photo-eye. Check to be sure the bulb's sensor (it may look like a black lens on the bulb) is getting enough sun to it. Make sure the sensor is facing toward the sun.
Why is my outdoor photocell not working
As discussed above, photocell sensors may not be working because they're covered in dust, dirt, debris, or other fixtures preventing light from entering the cells. What is this If this is the case, open the bulb and wipe away the dirt obstructing the sensors.
How long do outdoor photocells last
Photocell sensors have a lifespan of upwards of 10 years. They do go bad from time to time, though, especially if they aren't connected to stable wiring. In such cases, the best way to fix a bad photocell is to simply replace it.
What causes a dusk to dawn light to stay on
Dusk to Dawn bulbs have a light sensor built into the bulb that monitors the ambient light. The light sensor will automatically turn the light bulb on when it is dark and off when it is light. As a result, they operate a little differently than a regular light bulb.
How do you know if your sensor is messed up

Can dusk to dawn sensors go bad
They do go bad from time to time, though, especially if they aren't connected to stable wiring. In such cases, the best way to fix a bad photocell is to simply replace it.
How long do dusk to dawn sensors last
Whether you choose a 45-watt or 70-watt Dusk to Dawn light fixture, the expected duration of the lamps is 50,000 hours. Dusk to Dawn light fixtures are virtually maintenance free and you don't have to worry about replacing the bulbs for nearly 10 years.

Why won t my outside sensor light go off
The Problem
Some movement sensors have a built-in override functionality. If the override function is engaged, the sensor light will stay on until the override function is disengaged. This override function is often engaged accidentally which causes confusion and the mistaken belief that the sensor is faulty!

What happens when sensor fails
If a pressure sensor fails, it can cause the entire control system to fail and lead to inoperable equipment or system down time; depending on the type of system, significant damage can occur to the equipment and surrounding environment.
What happened when an sensor fails
A faulty sensor could result in the engine overheating, where the PCM doesn't know to turn on the fan when it is needed. Incorrect temperature readings could also result in the control system remaining in an "open loop", which is a temporary state only meant to occur when the engine is cold-started.
Why does my dusk to dawn light keep going off and on
Fluctuating voltage is one of the main reasons behind the blinking of dusk to dawn light. This implies that the light is getting exposed to brownout due to the amount of power taken in by it. Also, when the supply of power goes below a certain threshold, it will turn off.
What causes a dusk to dawn light to stop working
The main reason Dusk to Dawn lights don't turn on or stay on is that the sensor is frozen in the on or off position. The lights may also be turning off frequently at night because the sensors are detecting the light from other sources or from the lights themselves.
Why does the dusk till dawn light keep going on and off
Fluctuating voltage is one of the main reasons behind the blinking of dusk to dawn light. This implies that the light is getting exposed to brownout due to the amount of power taken in by it. Also, when the supply of power goes below a certain threshold, it will turn off.
How do you fix a sensor light that stays on
Reset your Motion Detector – To reset your motion light, unplug it from its power source for a full 10 seconds. Plug it back in and allow it to come back on. This should reset your light and turn off the auto-on function.
Why does my dusk to dawn light not turn off
Obstructed Sensors
If the sensors are obstructed by dirt, debris, or even shadows from trees, buildings, etc., they won't work as they should. Sensors rely on environmental cues to work, after all. Therefore, dusk to dawn lights should always be placed in an area with plenty of natural light.
What are the signs that the sensors are failing

What is the most common cause of sensor failure
Cable break / lead breakage, broken connectors and damaged cable insulation – many of these failure causes and sources of errors in sensors can be traced back to mechanical failure of qualitatively inferior components.
