Carbon monoxide (CO) is an odorless, colorless gas that can cause serious health problems, including death. CO alarms are an important safety device that can warn you of the presence of CO in your home. However, CO alarms can sometimes malfunction or give false alarms. If your CO alarm is not working properly, you need to reset it.
Resetting a CO alarm is a simple process that can be done in a few minutes. However, it is important to follow the manufacturer’s instructions carefully. Resetting a CO alarm incorrectly can prevent it from working properly and could put you and your family at risk. It is important to test your CO alarm monthly to make sure it is working properly. You can do this by pressing the test button on the alarm. The alarm should sound a loud, beeping noise. If the alarm does not sound, it needs to be replaced.
If your CO alarm is sounding an alarm, it is important to take action immediately. Evacuate your home and call 911. Do not re-enter your home until it has been declared safe by the fire department. CO poisoning can be fatal, so it is important to take it seriously.
Identifying the Need for a Reset
Carbon monoxide alarms are essential safety devices that protect us from the dangers of this odorless, colorless gas. However, like all electronic devices, they can occasionally malfunction and require a reset. Identifying the need for a reset is crucial to ensure the continued effectiveness of your carbon monoxide alarm.
The following circumstances typically indicate that a carbon monoxide alarm reset is necessary:
1. Alarm Activation Without Carbon Monoxide Presence
One of the most common reasons for resetting a carbon monoxide alarm is false activation. This can occur due to various factors, such as:
- Improper installation or placement of the alarm
- Exposure to fumes from cooking, cleaning products, or other sources
- Power fluctuations
- Malfunctioning sensor
| Signs of False Activation | Causes of False Activation |
|---|---|
| Chiming or beeping after installation | Improper placement near combustion appliances or exhaust vents |
| Frequent nuisance alarms during cooking or cleaning | Proximity to gas stoves or cleaning products containing chlorine |
| Random activation | Power fluctuations or faulty wiring |
If you suspect false activation, it’s important to reset the alarm and investigate the potential causes. If the nuisance alarms persist, it’s recommended to consult a qualified electrician or HVAC technician for further evaluation.
Locating the Reset Button
Resetting a carbon monoxide alarm requires locating the designated reset button, which is typically marked with a clear label or symbol. Identifying this button is crucial for proper alarm functionality.
Types of Reset Buttons
Carbon monoxide alarms utilize various types of reset buttons, each with distinct characteristics:
| Button Type | Characteristics |
|---|---|
| Push Button | Requires pressing firmly until a click is heard |
| Toggle Switch | A lever-like button that flips from “Test” to “Reset” |
| Combination Button | Pressing and holding activates the test function, while a separate button press initiates the reset |
Button Location
The reset button’s location varies depending on the alarm model and manufacturer:
- Front Panel: Commonly found on the front or side of the alarm, clearly marked with a “Reset” label.
- Interior Compartment: Some alarms necessitate opening the enclosure to reveal the reset button, usually concealed behind a cover or removable panel.
- Battery Compartment: Certain alarm models place the reset button within the battery compartment, with a corresponding label or symbol.
Step-by-Step Guide to Resetting the Alarm
1. Identify the Buttons

If all else fails, follow these advanced reset procedures:
- Remove the alarm from its mounting bracket.
- Locate the two wires connected to the alarm’s terminals.
- Disconnect both wires and twist them together.
- Wait 10 seconds, then reconnect the wires to the terminals.
- Reinstall the alarm and power it on.
Testing the Alarm After Reset
After resetting your carbon monoxide alarm, it’s crucial to test it to ensure it’s functioning correctly. To do this, follow these steps:
- Use the provided test button to simulate carbon monoxide detection. The alarm should sound a loud and distinct signal.
- Hold the test button for a few seconds. If the alarm continues to sound, it indicates it’s operational.
- Check the manufacturer’s specifications to determine the specific test procedure for your particular alarm.
- If the alarm fails to sound or operates abnormally, replace it immediately. A faulty alarm could jeopardize your safety by providing false readings or failing to alert you in the event of a carbon monoxide leak.
Additional Troubleshooting Tips
If you encounter any issues while resetting or testing your carbon monoxide alarm, consult the manufacturer’s user manual or contact their customer support team. Common troubleshooting tips include:
| Problem | Solution |
|---|---|
| Alarm beeps intermittently | Check battery power; replace if necessary. |

Additional Tips for Efficient Alarm Operation
In addition to resetting your carbon monoxide alarm, there are a few other things you can do to ensure that it is operating efficiently.
Test your alarm regularly. Test your carbon monoxide alarm at least once a month by pressing the test button. If the alarm does not sound, replace the batteries or the alarm itself.
Replace the batteries annually. Even if your alarm is not sounding, it’s important to replace the batteries once a year. This will ensure that the alarm has enough power to function properly.
Keep the alarm clean. Dust and dirt can accumulate on the alarm’s sensor, which can affect its ability to detect carbon monoxide. Clean the alarm regularly with a soft cloth or compressed air.
Install the alarm in the right location. Carbon monoxide alarms should be installed in every bedroom, as well as in the hallway outside of bedrooms. The alarms should be mounted at least 4 inches from the ceiling and at least 6 inches from any walls or furniture.
Avoid placing the alarm near sources of moisture. Moisture can damage the alarm’s sensor. Do not install the alarm in bathrooms, laundry rooms, or near windows that are frequently opened.
Do not paint the alarm. Paint can block the alarm’s sensor. If you need to paint the wall where the alarm is installed, use a light touch and avoid getting paint on the alarm itself.
Replace the alarm every 5 to 7 years. Carbon monoxide alarms have a limited lifespan. After 5 to 7 years, the sensor can become less sensitive and the alarm may not be able to detect carbon monoxide properly. Replace the alarm every 5 to 7 years to ensure that it is working properly.
| Type of Alarm | Lifespan |
|---|---|
| Battery-operated alarm | 5 to 7 years |
| Plug-in alarm | 5 to 7 years |
| Hardwired alarm | 10 years |
