Reasons Why Moen Motionsense Faucet Won’t Turn Off
There are a few potential causes for your Moen Motionsense Faucet not turning on.
The Batteries May Have Died Out Or Not Been Installed Properly
One of the most common causes of your Moen Motionsense faucet not working is an issue with the batteries. Over time, the batteries can die out or become disconnected. If this has happened in your case, check to make sure they are properly installed and replace them if needed.
Faulty Data Cable Connection
If the Moen Motionsense Faucet won’t turn on, it might be due to a faulty data cable connection. To check this, first ensure that the power adapter is securely plugged into both the power outlet and the control box of your faucet.
Additionally, make sure that the data cable connecting the motion sensor to the control box is firmly connected. If not, gently push it in and make sure it’s securely seated. Next, toggle the main power switch located at the bottom of your Moen Motionsense Faucet to turn it off and then back on again.
Alternatively, you can also unplug the power adapter from the wall and plug it back in. This should reset your motion sensor and help resolve the issue.
Problems With The Control Box
If the faucet still won’t turn on, the problem may be with the control box. The control box is a thin metal box located either behind or under your sink and contains the electronics that control the Moen Motionsense Faucet. If you’re sure all of your batteries are in good condition, but your faucet still won’t turn on, then the control box may be faulty.
You’ll need to open up the control box and check for any loose connections or other issues. To do this, you’ll need a screwdriver to unscrew the screws that are holding it to your countertop or sink cabinet. Inside of the box, there should be a circuit board, which will have several wires and components connected to it. Make sure that all of the wires are properly connected and that none of them appear to be damaged or frayed. If you notice any issues, then the control box may need to be replaced.
Once you’ve made sure everything is in order with the control box, you should be able to turn on your Moen Motionsense Faucet. If the faucet still won’t turn on, then there may be an issue with the sensor itself and you’ll need to contact a professional for assistance. Once you’ve identified and solved the underlying issue, make sure that all of the connections are secure and that your Moen Motionsense Faucet is working properly before using it. 
Solution For Fixing When Moen Faucet Won’t Turn Off
If your Moen Motionsense faucet won’t turn off, then there are a few different steps you can take to attempt to troubleshoot and fix the issue.
Issues With The Battery
If your Moen motionsense faucet isn’t turning on, then you may be dealing with an issue with the battery. The most common cause for this is that the battery is not properly connected. To locate and access the battery compartment, use a flathead screwdriver to remove the cover plate from beneath the handle. After you have the cover plate off, you should see the battery compartment with two screws and a clip to hold the battery in place.
Issues With Data Cable
The Moen Motionsense faucet may not turn on due to a faulty data cable. If this is the case, you will need to remove the data cable from the wall and check for any damage or corrosion. If there is any visible damage, it should be replaced with a new one. After replacing the data cable, it should be reconnected to the wall and you can check if the faucet turns on.
Issues With Control Box
If the Moen Motionsense faucet isn’t turning on, you may have an issue with your control box. The control box is responsible for powering the faucet and allowing it to detect motion for activating and deactivating the water flow. To troubleshoot, first check if the power cord is properly connected to the control box. If the cord is connected but there is still no power, you may need to replace the control box entirely. This can be done by unscrewing the bolts from the mounting plate and gently pulling away from the sink.
Another issue with the control box could be water damage or corrosion on the board. If this is the case, you’ll need to replace it. When replacing the control box, make sure all of the wires are connected properly before turning on the power. Once it’s connected, turn the faucet off and then back on again to ensure proper functionality. 
Moen Motionsense Faucet Turns On By Itself
If your Moen Motionsense faucet is turning on by itself, it may be because the sensitivity of the motion sensor has been set too high. To adjust the sensitivity, first make sure that nothing is obstructing the range of motion of the sensor and then turn off the water to avoid any messes while making adjustments. After locating the motion sensor adjuster knob, use a flathead screwdriver to turn it clockwise or counter-clockwise until the desired sensitivity is reached.
How To Turn Off Moen Sensor Faucet
- Find the power switch located beneath the sink – this is usually a toggle switch or button on the base of the faucet.
- Once you’ve found it, simply turn it off and wait at least thirty seconds before attempting to restart your Moen MotionSense Faucet.
- If your Moen MotionSense Faucet is still not turning on, check the batteries located inside the faucet handle – they may need to be replaced.
- Once you’ve done that, try restarting your faucet again and it should now work correctly.If you’re still having trouble getting your Moen MotionSense Faucet to turn on, it may be due to a fault with either the faucet handle or its sensors. 
Why Is My Moen Kitchen Faucet Leaking
Leaks in Moen kitchen faucets often occur due to a worn out O-ring or cartridge, which is the part of the faucet that controls water flow. If your Moen kitchen faucet is leaking, check the O-ring and/or cartridge for damage or wear and tear. It may be necessary to replace the O-ring and/or cartridge in order to stop the leak.
If you have a Moen Motionsense faucet, it may be caused by a faulty battery or low power connection. Check the batteries and connections to ensure that there are no issues that could be preventing your Moen Motionsense faucet from turning on. If the battery or connections are low, replace them with new ones.
If you’re still having trouble with your Moen Motionsense faucet not turning on, it may be due to a build-up of dirt and debris in the sensors or the lines leading to them. Clean all of the sensors and lines thoroughly to ensure that they are not blocked. If necessary, you may need to replace the sensors or the lines if they are too clogged up with dirt and debris.
Tips For Fixing A Moen Motionsense Faucet That Won’t Turn On
