When a carbon monoxide detector does not function properly, this can pose a significant risk to those who don’t respond quickly.
This is why you will want to stay on top of what the carbon monoxide detector is trying to alert you about when it beeps.
This includes a situation where the carbon monoxide detector goes off in the middle of the night.
If a carbon monoxide detector goes off in the middle of the night, this means the battery needs to be replaced, it’s starting to age, or the temperature is too low where the detector is installed.
In general, a carbon monoxide detector should be installed at room temperature. This will ensure it does not get impacted by a sudden drop in temperature.
However, in some parts of the home, the temperature can drop during the night. This leads to a situation where the carbon monoxide detector goes off in the middle of the night.
This guide will take a look at what to do when the carbon monoxide detector beeps at night randomly.

Reasons Your Carbon Monoxide Detector Goes Off In The Middle Of The Night
1. Low Battery
If a carbon monoxide detector goes off at night, you will want to make sure it’s not alerting you about a potential leak.
If this is a constant issue then you can begin to troubleshoot the problem to figure out what is causing the false alarm.
For the most part, the issue is going to have to do with the battery.
Each carbon monoxide detector has a built-in mechanism to alert homeowners about a dying battery.
This is to make sure you change the battery before things worsen.
If you notice this, the best course of action is to make sure you are replacing the battery as soon as possible. Don’t delay this as it will become a safety risk.

2. Aging Detector
This is a potential reason for a carbon monoxide detector beeping at night.
It might be dying.
This happens when the detector has not been changed for years and is now at the end of its life.
This is natural and it is something you are going to see with any safety device at home whether it’s the smoke alarm or this unit.
As a result, you should be aware of when it’s time to replace the carbon monoxide detector.
The beeping at night is likely a warning sign that it is going to start to fade.
The best way to know this is by replacing the battery. If it continues to beep at night, this means you will have to change it as soon as possible.
3. Low Temperature
This is one of those situations that can happen when the carbon monoxide detector is set up in a room that is not kept warm.
During the day, the temperature is going to remain high, which means it is unlikely to trigger the carbon monoxide detector.
However, when the sun goes down, this is when the temperature drops rapidly.
If it is located in a colder part of the house, the sudden drop in temperature might cause the detector to start beeping.

4. Damaged Wiring
This is an issue some people note when it comes to the detector.
The wiring tends to get ruined over time and you will have to act fast. If there is wiring hooked onto the carbon monoxide detector, you will want to take a proper look at it.
This includes wiring inside the unit.
There are times when the wiring might loosen and you will have to tighten it. This can be done within seconds and should bring the unit back to how it was.
It is also recommended to reset the carbon monoxide detector by turning off the power and then turning it on again.
Can Carbon Monoxide Alarms Go Off For No Reason?
Carbon monoxide alarms can go off for no reason. This can happen once a carbon monoxide alarm is beginning to near the end of its life. This will make it far more erratic and dysfunctional.
How Do You Know If Carbon Monoxide Is A False Alarm?
You will know a carbon monoxide is a false alarm is when the beeping happens sporadically throughout the day. This likely means the detector is either dying or the battery has to be replaced.
Final Thoughts
These are the reasons why your carbon monoxide detector goes off in the middle of the night.
If a carbon monoxide detector goes off in the middle of the night, this means the battery needs to be replaced, the detector is starting to age out, or the temperature has dropped suddenly in the room.
It is best to start by replacing the battery and seeing if that helps before looking at changing the detector.
